San Mateo County Health Officer Scott Morrow informed residents on Monday night he believes the county has identified less than five percent of the total COVID-19 infections since the outbreak began.
"I hesitate to give you the following numbers, because first of all they are a guess, and secondly because some will think they are too low to take action," he wrote. "My best guess is that approximately 2-3% of the SMC population are currently infected or have recovered from the infection. That’s around 15-25,000 people and they are all over the county and in every community. I don’t believe this number is off by a factor of 10, but it could be off by a factor of 2 to 3. Without the [shelter-in-place order], it could have well been over 50-75,000 by now, and that would have overwhelmed our healthcare system."
The county has just 699 confirmed cases of the virus; if Morrow's numbers are correct, that would mean the county has identified just 2.7-4.5 percent of its total cases.
"This virus appears to be wildly transmissible especially within households or congregate settings," he wrote. "Your risk from contracting the infection from any human you encounter in San Mateo County and outside your immediate household continues to be substantial unless you take all the recommended actions to protect yourself."
However, if his numbers hold, that would place the mortality rate for the virus somewhere between .08 percent and .14 percent, well below the county's current figure of 3.14 percent. There have been 21 total recorded deaths in the county to this point.
