COVID-19 pandemic
The Centers for Disease Control and Prevention this week changed its COVID-19 testing guidelines to say that people who've been in close contact with someone known to have COVID-19 but are asymptomatic now "do not necessarily" need to get tested. Health experts are expressing alarm over this revision since, for example, up to 50 percent of all COVID-19 transmissions are due to people who do not exhibit symptoms of the disease.
