COVID 19 UPDATE
From symposium yesterday of infectious disease specialists in California, many of whom had treated patients with the virus.
1. The most common presentation was one week prodrome of myaglias, malaise, cough, low grade fevers gradually leading to more severe trouble breathing in the second week of illness. It is an average of 8 days to development of dyspnea and average 9 days to onset of pneumonia/pneumonitis. It is not like Influenza, which has a classically sudden onset. Fever was not very prominent in several cases. The most consistently present lab finding was lymphopenia (with either leukocytosis or leukopenia). The most consistent radiographic finding was bilateral interstitial/ground glass infiltrates. Aside from that, the other markers (CRP, PCT) were not as consistent.
2. Co-infection rate with other respiratory viruses like Influenza or RSV is 24 hours apart.
10. All suggested ramping up alternatives to face-to-face visits, tetemedicine, “car visits”, telephone consultation hotlines.
11. Sutter and other larger hospital systems are using a variety of alternative respiratory triage at the Emergency Departments.
12. Health Departments (CDPH and OCHD) state the Airborne Infection Isolation Room (AIIR) is the least important of all the suggested measures to reduce exposure. Contact and droplet isolation in a regular room is likely to be just as effective. One heavily affected hospital in San Jose area is placing all “undifferentiated pneumonia” patients not meeting criteria for COVID testing in contact+droplet isolation for 2-3 days while seeing how they respond to empiric treatment and awaiting additional results.
