What does a purple tier mean in California during the COVID-19 pandemic? Purple, or Tier 1, indicates that the virus is widespread in the county — with more than seven cases per 100,000 residents or more than 8% of tests results reported positive over seven days.
Can COVID-19 be spread through sex? The virus spreads by respiratory droplets released when someone with the virus coughs, sneezes or talks. These droplets can be inhaled or land in the mouth or nose of a person nearby. Coming into contact with a person’s spit through kissing or other sexual activities could expose you to the virus.
How long can COVID-19 linger in the air? The smallest very fine droplets, and aerosol particles formed when these fine droplets rapidly dry, are small enough that they can remain suspended in the air for minutes to hours.
Which groups of people are at increased risks of severe illness from COVID-19? Among adults, the risk for severe illness from COVID-19 increases with age, with older adults at highest risk. Severe illness means that the person with COVID-19 may require hospitalization, intensive care, or a ventilator to help them breathe, or they may even die. People of any age with certain underlying medical conditions are also at increased risk for severe illness from SARS-CoV-2 infection.
