Plunging demand for tests may leave U.S. exposed
WASHINGTON - Just five we e ks ago, Los Angeles County was conducting more than 350,000 weekly coronavirus tests, including at a massive drive-thru site at Dodger Stadium, as health workers raced to contain the worst COVID-19 hotspot in the U.S.
Now, county officials say testing has nearly collapsed. More than 180 government-supported sites are operating at only a third of their capacity.
“It’s shocking how quickly we’ve gone from moving at 100 miles an hour to about 25,” said Dr. Clemens Hong, who leads the county’s test- ing operation.
After a year of struggling to boost testing, communities across the country are seeing plummeting demand, shuttering testing sites or even trying to return supplies.
The drop in screen- ing comes at a significant moment in the outbreak: Experts are cautiously optimistic that COVID-19 is receding after killing more than 500,000 people in the U.S. but concerned that emerg- ing variants could prolong the epidemic.
“Everyone is hopeful for rapid, widespread vaccinations, but I don’t think we’re at a point where we can drop our guard just yet,” said Hong.“We just don’t have enough people who are immune to rule out another surge.”
U.S. testing hit a peak on Jan. 15, when the country was averaging more than 2 million tests per day. Since then, the average number o daily tests has fallen more than 28%. The drop mirrors declines across all major virus measures since January, including new cases, hospitalizations and deaths.
Officials say those encouraging trends, together with harsh winter weather, the end of the holiday travel season, pandemic fatigue and a growing focus on vaccinations are sapping inter- est in testing.
“When you combine all those together you see this decrease,” said Dr. Rich- ard Pescatore of the health department in Delaware, where daily testing has fallen more than 40% since the January peak. “People just aren’t going to go out to test- ing sites.”But testing remains important for tracking and containing the outbreak.
