Korean Respiratory Outbreak Investigation – Day 7


# 10, 691



Although Korean investigators have yet to isolate a cause of the pneumonia outbreak centered around the Animal Life Sciences building at Konkuk University, there is good news today as no new cases (suspected or confirmed) have been added over the past 24 hours.


The case counts remains at  52 pneumonia cases in isolation and 28 with mild respiratory symptoms in home quarantine. None of the pneumonia cases are listed as severe, and many are now showing signs of recovery.


More than 1600 others – contacts of  patients or having exposure to the building - are being monitored. All of the pneumonia cases worked on floors 3-7 of the Life Sciences building. Other than 5 positive tests for Rhinovirus (considered an incidental finding), none of the extensive testing has revealed a plausible cause.


Serological testing, while negative so far, will need to be repeated in a couple of weeks.


Given the gradual slowdown in cases a week after the life sciences building was closed, and the lack of any secondary transmission to family contacts, investigators increasingly suspect an environmental contaminant (fungal, bacterial, or chemical) may be involved.  


Answers may take awhile, as environmental testing – particularly for fungi – can take several weeks or even months.

Tomorrow (11/5) an advisory panel will meet to discuss the case-control study and to assess the epidemiological investigation into this outbreak.  Hopefully we’ll get more details then.

This (translated) update comes from the Korean CDC.
