ECDC Comment & WHO Update On Spain’s Ebola Case

image

 

 


# 9170

 


Given that Spain’s locally-acquired Ebola case was considered a `low risk’ contact, and transmission occurred in a modern hospital facility that was aware they were treating an Ebola patient, and actually had previous experience doing so,  there is intense interest in just how she came to be infected.

 

While theories abound, it is possible we’ll never know for sure.

 

This nosocomial transmission has prompted the ECDC to declare they will re-assess Ebola Transmission risks in Europe (see Ebola case in Spain: ECDC to re-assess transmission risk for Europe).  An excerpt from their statement, released earlier today,  reads:

 

"It is our mandate to re-assess the risk to the EU”, says ECDC Director Marc Sprenger, “and we are confident that infection control protocols in Europe are of high standard and remain appropriate if strictly adhered to. But there is no such thing as a zero per cent risk of infection. It is important to understand that the risk of Ebola to Europe can only be eliminated by stopping the outbreak in West Africa.”

Two ECDC experts are currently in Madrid to support the local authorities in their investigations of the mechanism through which the nurse has been infected. Once this information is available, ECDC will consider the possible implications on the transmission risk to Europe in its updated risk assessment.

 

Meanwhile the World Health Organization has released the following update on Spain’s Ebola case.

 

 

Ebola virus disease – Spain

Disease outbreak news
9 October 2014

On 6 October 2014, the World Health Organization (WHO) was informed of the first confirmed autochthonous case of Ebola virus disease (EVD) in Spain. This case represents the first human-to-human transmission of EVD outside Africa.

The case is a female healthcare worker with no travel history to West Africa but who participated in the medical care of an EVD case in a Spanish citizen, who had been infected in Sierra Leone and evacuated to Madrid, Spain on 22 September 2014 and who died on 25 September 2014. She was in contact with the repatriated EVD case twice; on 24 and 25 September 2014. On both occasions she is reported to have worn appropriate personal protection equipment (PPE).

Following the Spanish national protocol for EVD cases, the healthcare worker was considered a low risk contact and monitored accordingly. The female case developed a fever on 29 September 2014 and was admitted into isolation on 6 October 2014 at Alcorcon Hospital in Madrid. The case was then transferred to La Paz-Carlos III Hospital in Madrid and is being treated under isolation.

Samples were collected and sent for testing to the National Reference Laboratory on 6 October 2014. Results were positive for Ebola virus on the same day.

The Spanish public health authorities are conducting an investigation to elucidate the mode of transmission. Identification of close contacts for daily monitoring for 21 days after exposure is underway for the recent case and is continuing for contacts of the Spanish citizen who was treated in Spain.

As for all countries reporting EVD cases, future WHO updates on EVD in Spain will not be posted on the Disease Outbreak News. Further information will be available in WHO’s Ebola situation reports which provide regular updates on the WHO response:

Spain: MOH Statement On Ebola Infected Nurse & News Roundup

image

 

# 9155

 

In a follow up to yesterday’s report (see Nurse `Infected With Ebola’ In Madrid, Spain) we are seeing more details emerge, including demands from the EU for clarification on how this infection could have occurred (see AFP article EU demands explanation from Spain on Ebola case) in a modern hospital that knew they were receiving and treating an Ebola case.

 

ABC News is reporting that Spain Places Husband of Ebola Nurse in Quarantine – a reasonable precaution given his risks of exposure – and that the MOH is drawing up a list of others who may have had contact with this nurse so that they can be monitored.

 

Although we know how to protect against infection with the Ebola virus, the reality is, no system of infection control is infallible.  There are reports overnight in the media of complaints over `substandard PPEs’ provided by the Spanish hospital, although authorities are still insisting all proper infection control procedures were followed.

 

Quickly getting to the bottom of how this exposure occurred – and making adjustments to prevent it from happening again -  will be paramount to prevent a crisis of confidence in the ability of modern hospitals to take in, and care for Ebola cases,  without endangering their staff.  

 

For now, the Spanish MOH is being circumspect on releasing details of this nurse’s contacts, or travel history, during the six days after she began to feel unwell, but was not isolated.  A tactic that, unfortunately, may lead to more intense speculation online and in the media.

 

While it isn’t currently visible from the front page of Spain’s Ministry of Health website, there is now a brief press release posted under the  Actualidad (news)  banner.

 

Press Releases

Diagnosed a secondary case of Ebola virus infection

The patient was isolated at the Hospital La Paz Carlos III

The patient is a member of the medical staff who treated Manuel García Viejo

The Minister of Health, Social Services and Equality, Ana Mato, sends a message of calm and highlights the absolute coordination with health authorities both nationally and internationally

6 October 2014 The Minister of Health, Social Services and Equality, Ana Mato, today reported the detection of a secondary case of Ebola virus infection in our country. The minister, who appeared together with the Director General of Public Health, Mercedes Vinuesa, Director of Primary Care, Community of Madrid, Antonio Alemany and healthcare professionals of the Community, explained that this is a medical technician who treated the Manuel García patient Viejo. After the symptoms have been detected and confirmed infection, remains hospitalized in isolation at the La Paz Hospital Carlos III.

The minister explained that the Ministry and the public health authorities of the Community of Madrid are working in a coordinated and are taking every step to give the best care to the patient and to ensure the safety of the population and health personnel . It has also indicated that it is investigating the source of infection.

He also stressed the absolute international coordination and recalled that Spain collaborates with the World Health Organization (WHO). Finally, you have moved a message of reassurance to all citizens.

Spanish Media: Negative Test Reported On Suspected Ebola Case

# 8781

 

Although I can find no official announcement on  Spain’s National Ministry of Health website, or Valencia’s Regional website, multiple news outlets in Spain are now reporting the the traveler from Morocco who fell ill on a flight into Valencia on Monday (see Spain Testing Traveler For Possible Ebola Infection) has tested negative for the virus.


 

HEALTH ALERT

Isolated on a patient suspected of suffering from Valencia Ebola

The analyzes have ruled out the disease in man, and Guinean nationals from Morocco

EFE / Valencia

Wednesday, June 25, 2014 - 18:54 pm

The analyzes carried out on a patient at the Hospital La Fe in Valencia, which had been isolated for suspected Ebola suffer, they have ruled out the virus and the disease entered Spain, sources have advanced the Ministry of Health.

 

The patient who was isolated at the La Fe Hospital in Valencia on suspicion of having the Ebola virus , originally from Guinea and landed at Valencia from Morocco , is recovering well from a clinical standpoint.

 

The Minister of Health of Valencia, Manuel Llombart, said the patient, who has not offered more data, a series of symptoms during a flight from Morocco, such as the need for oxygen and nasal bleeding, which were suspected to crew could be infected by Ebola virus.

 

He then warned the health service abroad, he was isolated in the same plane, he was picked up at the airport and he was moved to the garage of infectious patients Faith.

 

Although not an altogether unexpected outcome, I’ll continue to try to find an official statement confirming this report.

Spain Testing Traveler For Possible Ebola Infection

UPDATED 1350 HRS EDT:  Spanish Media: Negative Test Reported On Suspected Ebola Case

 

# 8779

 

While we don’t know yet if it will amount to anything, over the past 16 hours or so the Spanish press has been reverberating with reports of a suspected imported Ebola case, hospitalized and being tested, in Valencia (see FluTrackers thread). 

 

The patient, who apparently fell ill (shortness of breath, fever, nosebleed) on a flight from Morocco on Monday, is reportedly  `clinically stable’ in isolation at Hospital La Fe de Valencia, as test results are awaited.  

 

Given the ongoing Ebola outbreak in West Africa (see WHO Ebola Update – June 24th), and out of an abundance of caution, anyone with recent travel history to the region who displays signs of severe illness is likely to trigger a full scale public health response such as this. 

 

Typical of the media coverage of this event is the following from Teinteresa.es.

 

The possible case of Ebola evolves favorably isolated on Faith

  EFE , Castellón

The patient is isolated in the hospital La Fe suspected of having Ebola, of Guinean origin and landed in Valencia from Morocco, is progressing well from a clinical point of view while trying to determine if you have this pathology.

 

The Minister of Health, Manuel Llombart, has provided this information on statements to the media in Castellón, where today signed a collaboration agreement with the University Jaume I.

 

According Llombart, the patient, who has not offered more data, presented a series of symptoms during a flight from Morocco, as oxygen requirement and nasal bleeding, they did suspect the crew that could be infected by the Ebola virus.

(Continue . . .)

 

The prodromal symptoms of Ebola infection are nonspecific enough that they could be easily confused with a number of other viral (or malarial) illnesses, and so we’ll have to wait for test results before we know the score.  But even if this patient tests positive, the rapid isolation of the patient by local public health authorities is likely to prevent further spread.

 

Movies like 1995’s Outbreak with Dustin Hoffman, and books like Tom Clancy’s Executive Orders and The Hot Zone by Richard Preston, have helped to turn Ebola into the ultimate nightmare disease in the eyes of the public.

 

But the reality is, the spread of African Viral Hemorrhagic Fevers (VHFs which includes Ebola, Marburg & Lassa) have traditionally been geographically limited. The illness strikes quickly, with profound and debilitating symptoms, and that helps to limit human-to-human spread.

 

That isn’t to say it is inconceivable for one of these viruses to be exported outside of Africa. After all, over the past decade we’ve seen three cases of Lassa fever imported in the United States (see Minnesota: Rare Imported Case Of Lassa Fever). 

 

But for now, the risks of seeing Ebola get a foothold outside of Western and Central Africa is considered low. 

 

In the most recent ECDC Rapid Risk Assessment on Ebola (June 9th), experts worked out several scenarios where the Ebola virus might travel to the European Union, including a scenario similar to the one that is currently under investigation. 

 

As you will see, the recommendations are quite specific, and not as draconian as many might suppose:

 

Scenario 3: Passenger with symptoms compatible with EVD on board an airplane

Cabin crew that identify a sick passenger on board and suspect an infectious disease, and ground staff receiving the passenger at the destination, should strictly follow the IATA guidelines for suspected communicable diseases.

These guidelines provide information on how to handle a sick passenger during the flight, how to reduce the risk of transmission on board the aircraft, how to communicate the event to the destination airport, and how to record  contact details on passenger locator cards for the passengers in the two rows around the case. Public health authorities and emergency medical services at the airport of destination should be informed in advance of arrival.

On arrival, the sick passenger should be put in a separate room awaiting medical assessment. The assessment of possible exposure to ebolavirus and of the compatibility of the symptoms with Ebola virus disease is outside the  scope of the airline crew’s actions and should be performed by medically trained ground staff.


The population incidence of Ebola virus infection is low, even during an outbreak, and it is considered highly
unlikely that a passenger infected with Ebola virus boards an airplane. In addition, the prodromal presentation of the disease is not characteristic enough to distinguish an Ebola virus infection from many other viral diseases. The public health response to a sick passenger on an aircraft should be based on a thorough assessment of the patient’s possible exposure to ebolavirus rather than on the clinical presentation. The evaluation of the exposure should check if, within the past three weeks, the passenger has:


•  visited a country where ebolavirus disease has been confirmed (for the current outbreak: Guinea, Sierra Leone and Liberia); AND
•  been in contact with a sick or dead wild animal (particularly bats) while there;

OR

•  cared for and touched a severely ill or dead person.

A ‘yes’ to question 1 and to either question 2 or 3 would signify that the ill passenger has been potentially exposed to Ebola virus in an affected country in the past three weeks. If the investigation does not conclude a  significant  risk of exposure to ebolavirus (no specific exposure for the sick traveller, no symptoms during the flight), contact tracing is not indicated. If the passenger is at risk of having been exposed to Ebola virus, the following epidemiological measures based upon proximity to the index patient should be considered (ECDC RAGIDA guidelines):


•  Passengers and crew with reported direct contact


Co-travellers and crew members who had reported direct body contact with the index case should be tracedback. To gather this information, any records of significant events on the flight should be obtained from the airline.

•  Passengers seated one seat away from the index patient

As direct contact is the main route of transmission for Ebola virus, only passengers who were seated one seat
away from the index case in all directions should be included in the trace-back. If the index case occupied an
aisle seat, the three passengers seated directly across the aisle from the index case should also be traced-back.

•  Crew members of plane section

Crew members who provided in-flight service in the section of the aircraft where the index case was seated
should be included in the trace-back, as well as other crew members who had direct contact with the patient.

•  Cleaning staff of plane section

The staff that cleaned the section seat where the index case was seated and the toilet facilities (if used by the
index case) should be traced-back.

Traced-back passengers, crew members and cleaning staff who have been identified should be assessed for their specific level of exposure. The risk for transmission is considered low if no direct contact with the passenger or with material potentially contaminated by the passenger’s bodily fluids has occurred. Self-monitoring of temperature should be considered for 21 days for all contacts. The same measures should be considered when a patient reports symptoms during a flight but fails to alert the crew.


There is no reason to quarantine the airplane upon arrival when a passenger presents with symptoms during the flight.

 


It should be noted that we don’t know if the suspect case meets the criteria (had recent contact with sick or dead wild animals or cared for or touched a severely ill or dead person), only that he supposedly hails from Guinea and fell ill on the flight. 

 

Hopefully we’ll get test results later today to either confirm or rule out Ebola. 

 

But either way those tests come out the risks to his fellow airline passengers, the general public in Spain (and the rest of Europe), remain low.

ECDC: Rapid Risk Assessment On MERS-CoV

# 7944

 

Yesterday’s announced imported case of MERS-CoV into Spain (see Spain: MOH Statement On MERS-CoV Case) has prompted a very rapid response from the ECDC, which posted their 8th update on this emerging coronavirus this morning.

 

As you’ll note by the timeline, this patient apparently spent two weeks with respiratory symptoms before seeking medical aid, was diagnosed with pneumonia at a hospital in Mecca on October 29th, yet her MERS-CoV infection status was not picked up by Saudi Surveillance and she was allowed to fly home two days later.  

 

She flew back to Spain on November 1st,  where she was isolated, tested, and eventually diagnosed with MERS.   Why she wasn’t identified by Saudi Surveillance and isolated in Mecca is, for now, unknown.

Event background


On 6 November 2013, Spain reported a case of MERS-CoV infection in a 61-year-old female with no known chronic conditions. She stayed in Saudi Arabia from 2 October to 1 November 2013, initially in Medina, then in Mecca for the Hajj. No contacts with animals or confirmed cases were reported. 

She flew from Jeddah to Madrid on 1 November 2013.


The onset of symptoms was reported as of 15 October 2013 (cough, fever) and she was seen at the emergency ward in Mecca Hospital on 28 and 29 October where pneumonia was diagnosed through chest x-ray. 

During the return flight she was symptomatic and required oxygen while in the aircraft. She was taken to a hospital in Madrid, admitted with the diagnosis of pneumonia and isolated as per guidelines. This patient is now in a stable condition.


On 5 November 2013, initial PCR laboratory test for MERS-CoV screening was positive on three different samples. Further tests for case confirmation are pending. 

On 6 November, the Spanish authorities implemented contact-tracing activities around family members of the case, healthcare personnel and patients that had been in close contact with the case. Passengers, as well as staff and crew from the airline, that had been in close contact with the case are also being traced. Naso-pharyngeal samples will be collected from them. No residents from other EU/EEA countries appear to be on the list of passengers seated within two rows of the index case.

Epidemiological situation worldwide


As of 7 November 2013, there have been 151 laboratory-confirmed cases of MERS-CoV worldwide, including 64 deaths. All cases have either occurred in the Middle East or have had direct links to a primary case infected in the Middle East. 


Saudi Arabia has reported 125 symptomatic and asymptomatic cases including 53 deaths; Jordan two cases, both of whom died; United Arab Emirates five cases, including one fatality; Qatar five cases, including two deaths; and Oman one case. 


Thirteen cases have been reported from outside the Middle East: in the UK (4), France (2), Tunisia (3), Germany (2), Italy (1) and Spain (1)

.
ECDC risk assessment for the EU

This is the 13th case reported outside of the Middle East, the tenth reported in EU/EEA Member States, the first reported in Spain and the first reported in the EU/EEA Member States since May 2013.

 
This case would correspond to an imported case in the EU, following exposure in Saudi Arabia and being symptomatic during the Hajj. The risk that the EU would see importation of new cases was stressed in the ECDC rapid risk assessment published on 24 September, and therefore, this situation was expected. 


The Spanish authorities have implemented tracing activities consistent with WHO and ECDC recommendations.


Therefore, the risk for further spread in the EU/EEA countries is considered extremely low.

Conclusions


The first case of MERS-CoV infection reported in Spain should remind EU citizens of the risk for contracting MERS-CoV through exposure while travelling to the Middle East. As indicated in previous risk assessments, such cases are expected to be reported in the EU, and in particular, among pilgrims returning from the Hajj.

 
EU/EEA Member States are investigating potential cases presenting suggestive symptoms on return from the Middle East. Until this case, all investigations turned out to be negative, but this finding confirms the need to  pursue efforts to rapidly investigate possible cases.

 

 

Meanwhile, Sharon Sanders on FluTrackers has picked up (somewhat conflicting) media reports of another possible MERS-CoV case in the UAE (see thread).   So far, there does not appear to be an official statement online. 

 

I’ll have more on this story, if and when more details surface.

Press Releases

Detected an imported case of the new coronavirus in Spain

  • The patient had traveled to Saudi Arabia
  • The patient, who remained during the month of October in Saudi Arabia, is located in a favorable position and stable
  • The case does not pose a risk to public health in Spain
  • Health authorities have followed national and international procedures for dealing with this case

November 6, 2013.'s Ministry of Health, Social Services and Equality has reported the detection of an imported case in Spain with positive laboratory results for human infection with the new coronavirus.

This is a woman living in Spain, born in Morocco, who had traveled to Saudi Arabia and is admitted to the Hospital Puerta de Hierro Majadahonda (Madrid), where they have taken all over the case, and on possible contacts as operating procedures agreed between the Ministry and the autonomous.

The patient, who was admitted on November 1, remains in a favorable and stable. The samples analyzed in the National Microbiology Center have tested positive to the new coronavirus infection.

The Ministry and the Community of Madrid are proceeding to identify all close contacts of the patient, as recommended in the procedures agreed at national and international level.

An imported case in which all these measures have been established, no risk to public health in Spain.

Following the provisions of the International Health Regulations, the Ministry of Health, Social Services and Equality has notified the World Health Organization and the European rapid alert network (EWRS), with which it maintains close monitoring of the situation, together with the Ministry of Health of the Community of Madrid.

NEW CORONAVIRUS

The Respiratory Syndrome coronavirus Middle East was identified in 2012 in Saudi Arabia. Most people affected by this respiratory virus acute respiratory disease presents with fever, cough and difficulty breathing.

To date there have been reported 150 confirmed cases, 125 of them in Saudi Arabia. All cases have been reported in five countries in the Middle East (Saudi, Jordan, United Arab Emirates, Qatar and Oman). In Europe there have been cases, all imported from this area, in four countries: United Kingdom (two cases), Germany (two cases), France (one case) and Italy (one case).

My thanks to Helen Branswell for tweeting the link to a report on Spain’s first confirmed case of MERS-CoV, diagnosed in a woman recently returned from Saudi Arabia and now hospitalized in Madrid. 

 

There are several news sources for this story, including the link from Helen from Europapress.es First case in Spain of the new SARS-like coronavirus, and the following report from El Pais.

Spain detects imported case of the new coronavirus

This is a Moroccan woman, who lives in Madrid and traveled to Saudi Arabia in October. The woman is entered and stable. Health now identified close contacts to verify their status

6 NOV 2013 - 18:11 CET

Health authorities have detected the first case of coronavirus in Spain. This is a woman of Moroccan origin living in Spain, who had traveled to Saudi Arabia in October. The hit, which is admitted to the Hospital Puerta de Hierro Majadahonda (Madrid) from November 1, is not in danger. The Ministry of Health, Social Services and Equality reported Tuesday that his prognosis is "favorable and stable".

 

The ministry and the Community of Madrid are now identifying closer contacts of the patient to make sure they are not infected by the new coronavirus. This respiratory pathogen was detected by the Agency of Health Protection in the UK (HPA) in 2012 on a 48-year catarí had been transferred to the UK. Since then the virus has affected 150 people - mostly in Saudi Arabia, where the focus - and killed 40. The in Spain is not the first case identified in Europe. Patients have been detected in the UK (two cases), Italy (one case), Germany (two) and France (one case), who had also imported the pathogen from the Arabian peninsula.

 

Most people affected by this virus, the Ministry of Health recalls in a note, have acute respiratory illness with symptoms of fever, cough and difficulty breathing. Ana Mato department ensures that an imported case, as detected in Madrid, and which have been established control measures "no risk to public health in Spain".

 

At this time, I’ve not found an official report from the Ministry of Health.  I’ll update as more details become available.

Spain: H5 Avian Flu In Doves

 

 

 

# 4921

 

 

A week ago, CopitoSP posting on FluTrackers from Madrid, Spain alerted forum members to an ongoing die off of `turkish doves’ in `Montjuïc and surrounding areas due to a disease of unknown origin’.

 

The original news item appeared in El Pais.com, and was titled Una enfermedad desconocida mata a cientos de tórtolas en los jardines de Montjuïc which translated works out to An unknown disease kills hundreds of pigeons in the gardens of Montjuïc.

 

An ongoing thread to track this event was created on FluTrackers, where you can read the full details of the story and follow up reports.

 

Today we have confirmation – courtesy of IronOreHopper - that HPAI H5 has been confirmed by FAO/Empres  (The Global Animal Disease Information System).

(Click Images to view)

 

While not exactly unheard of, HPAI infections in doves are fairly uncommon. 

 

A quick scan of my blog only turns up a handful of reports, including an Indonesian man from Tangerang  who – according to a Reuters report - was suspected to have contracted H5N1 from his neighbor's pet doves.

 

Doves were also mentioned in Thailand Issues Warning About Wild Birds, and Bird Flu Concerns In Dimapur, Nagaland.

 

Pigeons, however - which are of the same bird family (Columbidae) - have gotten somewhat more attention over the past few years, partially because they (and their feces) are so ubiquitous in many population centers.

 

I've written about the fear that pigeons might be vectors for the bird flu virus several times, including in The Origins Of The Feces  in December of 2006, and a year later in The Latest Poop On Pigeons.

 

Around the world, opinions vary over the threat these city dwellers present. In Bangladesh pigeons, along with ducks and chickens, are routinely culled in their fight against bird flu.

 

While in Saudi Arabia, they’ve claimed that pigeons are immune to the disease.

 

That may be a bit optimistic, since in May of 2007, in the CDC's  EID Journal , a dispatch appeared called Avian Influenza (H5N1) Virus in Waterfowl and Chickens, Central China,  where scientists deliberately infected a variety of birds to determine their susceptibility to the H5N1 virus.

 

Their study suggested that pigeons may be asymptomatic carriers of the avian flu virus.

 

Another study, from later that year, titled Role of Terrestrial Wild Birds in Ecology of Influenza A Virus (H5N1)  found that:

 

Least susceptible were pigeons, which had no deaths and very low levels of virus in oropharyngeal and cloacal swabs.

         <snip>

Because pigeons shed only low amounts of virus upon infection and they did not transmit to contact birds, their role in the ecology of influenza (H5N1) virus may be minor.

 

The good news is, since we haven't seen more than a few pigeon or dove related bird flu stories over the years, the evidence is scant that they pose much of a health threat to humans.

 

Of course, the H5N1 virus is constantly changing and evolving, and so that assessment could change in the future.
