Estimates of the severity of coronavirus disease 2019: a model-based analysis || This study published recently in The Lancet Infectious Diseases medical journal estimates that about 0.66% of patients who become infected with the virus will die (much different than previous estimates). When undetected infections aren’t taken into account, researchers found the coronavirus death rate was 1.38% (which is obviously the biggest concern since a lot of these cases most likely go undetected or that these people are not tested). This is still much higher than the flu which is 0.1%.
Incubation period | Median incubation period is estimated to be 5 days. For 97.5% of infected persons, symptoms appear by 11.5 days. Fewer than 2.5% are symptomatic within 2.2 days. Estimated median IT to fever was 5.7 days. This is HUGE when it comes to spreading the infection without knowing you are infected yet. Bottom line? STAY HOME. Here is an overview of incubation time.
Virological assessment of hospitalized patients with COVID-2019 || Very small sample size and not yet peer reviewed but bottom line is in milder illness, the virus was most infectious when patients had more mild symptoms and most infectious PRIOR to day 5 of illness. “Peak concentrations were reached before Day 5 and were more than 1,000 times higher” than those seen in SARS patients, the authors wrote. This may be different than patients with more severe illness requiring hospitalization.
