#10,572

 

The World Health Organization has released a new MERS update that characterizes 13 Saudi MERS cases reported between the 12th and 18th of September.

  

Cases were from  Riyadh (7),  Jeddah (3), and Madinah (2), and  Alqweiyha city (1). Of those, 4 are listed as Health Care Workers, although only 2 reportedly provided care to a known MERS patient.  Two other cases are listed at contacts of previously known cases, while a third received care from an infected HCW.

 


Illustrating just how convoluted some of these histories are, one of the Jeddah cases (#2 in the list) had recent travel to Amman, Jordan, where she was treated at a facility where MERS cases were admitted. She returned to Jeddah, was hospitalized, and treated by a (later) MERS positive HCW, and then tested positive two weeks later – giving her two plausible nosocomial exposures.

 

Of the 13 cases described, 8 have somewhat ambiguous routes of exposure, although the bulk have links to (worked at, or were admitted to) local healthcare facilities that were treating MERS patients.

 

Despite three years of dealing with MERS cases, Saudi Arabian hospitals continue to struggle to protect patients, staff, and visitors from this virus. Exactly why that should be, when other healthcare systems have had better luck limiting the nosocomial spread of MERS, remains a mystery. 

 

Middle East respiratory syndrome coronavirus (MERS-CoV) – Saudi Arabia

Disease outbreak news
27 September 2015

Between 12 and 18 September 2015, the National IHR Focal Point for the Kingdom of Saudi Arabia notified WHO of 13 additional cases of Middle East respiratory syndrome coronavirus (MERS-CoV) infection, including 1 death.

Details of the cases
  1. A 30-year-old male from Jeddah city developed symptoms on 11 September and, on 16 September, was admitted to hospital. The patient, who has no comorbidities, tested positive for MERS-CoV on 18 September. Currently, he is in stable condition in a negative pressure isolation room on a ward. The patient has a history of travelling to Riyadh and returning back to Jeddah on 3 September. Investigation of history of exposure to the known risk factors in Riyadh and Jeddah in the 14 days prior to the onset of symptoms is ongoing.
  2. A 72-year-old female from Jeddah city travelled to Amman, Jordan and was admitted to hospital for a medical procedure on 9 August. This hospital previously reported laboratory-confirmed MERS-CoV cases (see DON published on 18 September – case no. 1; see DON published on 1 September – case no. 2). The patient was discharged from hospital on 22 August and, on the same day, travelled back to Jeddah. She developed symptoms on 30 August and, on the same day, was admitted to hospital. Between 31 August and 4 September, the patient was taken care of by a laboratory-confirmed MERS-CoV case (see below – case no. 12). She has no history of exposure to other known risk factors in the 14 days prior to the onset of symptoms. The patient, who has comorbidities, tested positive for MERS-CoV on 16 September. Currently, she is in critical condition in ICU.
  3. A 63-year-old male from Riyadh city developed symptoms on 16 September and, on the same day, was admitted to hospital. He underwent medical procedure in the same hospital on 13 September. The patient, who had comorbidities, tested positive for MERS-CoV on 17 September. He passed away on 18 September. Investigation of possible epidemiological links with the MERS-CoV cases in the hospital or with shared health care workers is ongoing.
  4. A 14-year-old male from Riyadh city, who was identified through contact tracing, tested positive for MERS-CoV while asymptomatic on 17 September. The patient, who has no comorbidities, is a contact of a laboratory-confirmed case (see below – case no. 5). He has no history of exposure to other known risk factors in the 14 days prior to the onset of symptoms. Currently, he is still asymptomatic in home isolation.
