The MERS coronavirus has now spread from the Middle East to home town USA.

Since both US victims of this resurgent respiratory virus - one in Indiana and another in Florida - are healthcare workers, all eyes have turned to nosocomial transmission. In some locales nosocomial transmission has outpaced the former frontrunner for the MERS transmission prize: camel spit.

Proper infection control, therefore, is hugely important. The CDC recommends special airborne infection rooms, masks, eye protection, gowns and gloves. I remember taking these precautions when the SARS epidemic came through town. In some cases, patients were incredibly sick and it was scary; other times folks with SARS had the sniffles and we made a big deal over very little. Let's hope that as we learn more about MERS, the early reports of 30% case fatality will turn into less sobering statistics.

Along the way, it's good that the macho culture of medicine has been changing. When I was in training, it was common and even admirable for doctors to work sick. I remember idolizing a medicine resident who did morning rounds with an IV pole at his side. Yet now we know - how could we not have clued in then?! - that this risks spread of infectious diseases to our fragile patients.

In a nice story just out today titled "Second MERS Case Shows Hospitals Are Ground Zero for MERS," Maggie Fox of CBS News quoted me and others about MERS infection control.
