Here's when to seek emergency medical attention.

Earlier this month, the Omicron variant surpassed 95% of new COVID-19 cases in the U.S. Lucikly, Omicron seems to cause less severe symptoms than previous waves of the coronavirus. But any case of COVID can become serious and worthy of immediate medical attention. There are certain Omicron symptoms you should never ignore. Read on to find out more—and to ensure your health and the health of others, don't miss these Sure Signs You've Already Had COVID.


Omicron Usually Mild, But Can Be Severe

Studies have found that the Omicron variant is much less likely to cause serious illness or death than previous variants, including Delta. But Delta is still circulating—if you test positive, you mostly likely won't know what variant you have—and "less likely" doesn't mean "impossible." So it's important to know which symptoms warrant emergency medical care.

  • Shortness of breath or difficulty breathing
  • Fatigue
  • Muscle or body aches
  • Headache
  • New loss of taste or smell
  • Sore throat
  • Congestion or runny nose

Three new studies by the CDC have found that booster doses of the Pfizer and Moderna vaccines are about 90% effective at preventing hospitalization from the Omicron variant. They're also 82% effective in preventing visits to the emergency room or urgent care. "It really shows the importance of getting a booster dose," said the CDC's Emma Accorsi, one of the study's authors, last Friday. "Americans should get boosters if at least five months have passed since they completed their Pfizer or Moderna series, but millions who are eligible have not gotten them."

In a few weeks, doctors will be able to readily prescribe the antiviral drugs Paxlovid and molnupiravir.

The medications are being produced now and are in short supply.
