RE: Mers outbreak in Saudi Arabia puts health experts on high alert11 May 2024 10:16
I know what index case means Fruits - and this was clear in what I posted.
The teacher arrived in hospital and infected 2 patients: the first in A&E, the second in a shared room. Both patients were subsequently intubated in mid April.
MERS outbreaks historically spread within hospitals - with poor screening and diagnosis and a lack of ppe. This improved dramatically and serendipitously in Saudi and neighbouring countries during the pandemic as much stricter rules were introduced, and it's concerning that standards have slipped again. The WHO report recommends further re-education for hospital staff.
So we have one unexplained fatality and they're working to discover the original source of the infection. They've already tested dozens of family and contacts and found nothing and given the speed of infection to symptoms it really IS reasonable to suggest that 6 weeks after the teacher arrived at A&E - anyone he infected would be known by now.
The real index case for this outbreak is still unknown and remains a mystery, but MERS is a disease of dromedary camels and inevitably this WILL trace back in some way to a contact of some sort or infected milk.
"Most patients develop symptoms approximately 5 days after an exposure to an infected person or camel, but the incubation period can range from 2 to 14 days. In hospitalized MERS patients, the median time from the onset of symptoms to a person’s hospitalization is approximately 4 days. In critically ill patients, the median time from onset to ICU admission is approximately 5 days, and median time from onset to death is approximately 12 days.
