Mexican MOH: Bacterial Contamination Suspected Deaths & Illness in Chiapas

A couple of days ago a report surfaced from Chiapas, Mexico where tragically a large number of infants fell seriously ill, and two died,  after receiving routine vaccinations.

 

Bad Vaccines Kill 2 Babies, Sicken 29 in Chiapas, Mexico

MEXICO CITY — Mexico's public health system has suspended infant vaccines after two babies died and 29 were sickened in an impoverished community.

Six of the 29 babies are in grave condition after receiving vaccinations for tuberculosis, rotovirus and Hepatitis B, which are generally administered between 0 and 6 months, according to a national schedule. The cause of the adverse reactions is not known, the Mexican Institute for Social Security said Sunday.

Sadly, the `anti-vaccine brigade’ have quickly turned this tragedy into a cause célèbre, using it to `prove’ the that vaccines are unsafe, just as they attempted to do  last September when U.N.: At least 15 children die from bad measles vaccinations in northern Syria.

 

That tragedy turned out to be due to human error, not the vaccine, as we learned 10 days later from this statement by the World Health Organization.

 

Statement regarding interim findings of WHO assessment of deaths of children in Idleb Governorate, Syria

Statement
27 September 2014

A WHO assessment of the cause of the death of 15 children in rural Idleb, northern Syria has concluded that the most likely cause of the event was the incorrect use of a drug called Atracurium as a diluent for Measles/Rubella vaccine.

There is no evidence that the Measles/Rubella vaccine itself or its correct diluent were the cause of this tragic event.

Regarding this latest incident, Mexico’s IMSS has released a preliminary report that seems to exonerate the vaccines and implicates bacterial contamination instead.

 

IMSS report, Ministry of Health and COFEPRIS progress on developments in Chiapas

No. 036 /2015

Following the developments relating to girls and boys who allegedly adverse reactions associated with the use of vaccines in Pepper, Simojovel municipality, Chiapas, IMSS, community and the Ministry of Health COFEPRIS unveiled at conference Press the progress of the case.

Due to its improvement, it is being discharged to 10 more hospitalized children in the "Dr. Gilberto Gómez Maza ". As the 5 that were discharged yesterday, will remain under medical observation in the city of Tuxtla Gutierrez. Additionally, children of the 6 reported severe, 2 and are stable.

Of the 14 who remain hospitalized, 10 are stable and 4 are serious. The IMSS and the Ministry of Health of the state of Chiapas continue to work hard to keep giving them the best care.

Research on these unfortunate events continues. In order to keep the population informed promptly and provide certainty to all parents, is issued a partial conclusion: the targeted problem that occurred in the community Pepper, it was not due to a problem associated with the vaccine.

It was reported that the COFEPRIS analyzed batches of the vaccine and released in October last year, which was established that the vaccines were properly certified. Additionally, it was shown that of the 52 children who were given the vaccine in the Pepper, 21 community had no damages, in addition to the application of this vaccine in other parts of the country, which comes from the same batch, did not present negative reactions.

During the conference it was explained that one of the issues that led to the conclusion that vaccines were not chemically defective or wrong, is that culture results yielded local presence outside contamination, biological or outside the vaccine. This was reinforced by the fact that certain bacteria were found, which is consistent with the clinical pictures of children who have been hospitalized.

It announced that the investigation continues to determine the type of bacteria and the source of external contamination, so he entered a second stage of analysis.

The IMSS, the Ministry of Health, the COFEPRIS and the state government of Chiapas remain in close communication and collaboration in this case. As it has done, it will continue to report in a timely and appropriate manner.

 

 

There is obviously a lot we don’t know about this incident, including how this bacterial contamination occurred, and I obviously have no personal information on the matter.  We will hopefully learn more in the coming days. 

 

Reportedly this incident occurred in rural, low resource setting. The most likely scenario is that one or more of these vaccines required reconstitution, and that an expired or contaminated diluent was used (see PDF file Vaccines with Diluents: How to Use Them).

 

Unfortunately, no matter what the final verdict turns out to be, it will do little to `un-ring’  the anti-vaccine alarm bells that have been sounded across the internet over the the past few days.

Mexico: H7 Reported In Chiapas Nature Preserve, Nearby Zoo Closed

# 10,023

 

While the United States and Canadian poultry industry has been busy fighting HPAI H5 avian flu viruses, in Mexico the concern (thus far) has been for outbreaks of HPAI H7. 

 

Just shy of a month ago, we learned of two southern Mexican states – Oaxaca & Pueblo - recently hit by the H7N3 virus (see OIE: Mexico Reports HPAI H7N3 In Two States) – an avian strain which forced the culling of more than 22 million Mexican birds between 2012-13.

 

Beyond the tremendous economic damage to the Mexican economy, we also saw a couple of mild human infections with the virus back in 2012 (see MMWR: Mild H7N3 Infections In Two Poultry Workers - Jalisco, Mexico), resulting in conjunctivitis without fever or respiratory symptoms.

 

Although H7 avian viruses have had only a limited track record of causing human infection - until the H7N9 virus appeared in China just over two years ago (causing 200+ deaths) – H7 viruses were viewed as capable of only causing mild illness. 

 

 

Except for China’s unusual H7N9 virus, most H7 avian viruses are considered really only threat to the poultry industry.

 

That said, H7 flu strains - like all influenza viruses - are constantly mutating and evolving.  What is mild, or relatively benign today in humans, may not always remain so.

       

      All of which brings us to a pair of media reports (hat tip Gert Van der Hoek  on FluTrackers) indicating that roughly 30 grouse at a Chiapas Nature preserve have been found to be infected with H7 avian flu, and that a nearby zoo has been abruptly closed for `remodeling’ and over `animal health’ concerns.


      I’ve checked both the SENASICA and SAGARPA websites, and thus far have not found any official statement on this outbreak.  Similarly SENASICA’s Twitter feed has yet to mention it either.   

       

      Nevertheless, this story is being carried by multiple new agencies, and hopefully we’ll get a clarification from the Mexican authorities, or an OIE notification, in the next day or so.

      Mexico, DF.-In Chiapas , some 30 birds of origin wild , were eradicated by personnel of the National Health Service, Food Safety and Quality (SENASICA), because they were infected with the virus of bird flu .

      The authorities indicated that there is an outbreak, since this did not occur in a farm, but birds known as "grouse" were in a large nature reserve, near the Zoo Tuxtla Gutierrez. 

      SENASICA said that a fence a 10 kilometer radius of the reserve was established, and nearby farms were asked extreme security measures to prevent the spread of the virus.

      Meanwhile, Tuxtla Gutierrez Zoo closed its doors as a measure of protection to species.

       

         

        Burying the lede somewhat – as it doesn’t mention the H7 outbreak until the middle of the third paragraph – is this report from SDPNoticias.com.

        Regional zoo in Chiapas closed for renovations and maintenance

        Writing SDPnoticias.com Thu 07 May 2015 17:02

        Tuxtla Gutierrez, Chiapas.- Authorities regional zoo "Miguel Alvarez del Toro" (ZooMAT) in Chiapas, announced that from 12 to 25 May this year, the space is closed to the public for reasons of remodeling, major maintenance and animal health actions.

        Through a statement, the authorities unveiled that "ZooMAT is subject to a gradual transformation to optimize quality service to the public and provide greater comfort to the species housed in each of its campuses. However, work has intensified, implying the need to temporarily close its facilities not involve the safety of visitors ".

        It was also reported that birds found in total freedom inside the reserve, specifically chachalacas a detected outbreak of influenza H7, so the measures of health security will be strengthened to prevent birds sheltered in enclosures exhibition at risk of being infected.

        Although Mexico has been spared from dealing with the HPAI H5 virus currently affecting the United States, they may be at increased risk of seeing it next fall when the migratory birds now nestled in their northern breeding grounds head south.


        That said, there is nothing that says H7 viruses couldn’t hitch a ride on a northbound bird as well.
