As of February 29, 2020, In response to multiple complaints about the failure of current US test kits (let alone those used in China, Japan, South Korea, or Italy and Iran) to validate whether or not an individual actually has the COVID-19 virus, the FDA has gone to an emergency mode to allow all labs "certified" to perform "high complexity testing" (somewhere less than 100 in the US) without any bureaucratic delays such as prior public comment periods (can take months in most cases) and FDA oversight (further subsequent delays based on public comments). The purpose: develop a verifiable COVID-19 testing kit ASAP.
Given the 1st recorded US death from COVID-19, (Washington State), the "State of Emergency" in Santa Clara, CA and San Francisco, this action seems "better late than never'.
According to the several US virologists i have personally talked to, until we get reliable and longitudinal data out of Asia, it will remain difficult to determine who to test and who not to test even if we get improved testing kits. One puzzling cohort dichotomy is the under 40 age group versus the Chinese male (Ace2 dominant). Polar extremes in infection rates for some reason. Also, Why do we see a 15% "reinfection rate"? Does a "confounding" variable (i.e. COPD, immune system distress, smoking, diabetes, etc.) influence infection? Etc.
Whether claims to the effect by certain pharmaceutical firms about drugs or vaccines (generally "re-purposed" HIV-AIDS drugs or vaccines since apparently some virologists believe a link exists) are resulting in "cures" are questionable at this time.
