A doctor explains what to know and how to stay safe
COVID-19 cases are on the rise again across the U.S., with nearly 40 states reporting high levels of activity, according to the CDC. Emergency room visits for the virus are also at their highest since February.
Dr. Céline Gounder, a medical expert, explains that this summer surge is due to a few factors. First, the virus keeps evolving, making it harder for our immune systems to keep up. Second, immunity to infection tends to last only about three months, although protection against severe illness, hospitalization, and death lasts longer. This is why people aren’t getting as sick as they were earlier in the pandemic, but we can still expect big waves of COVID every few months.
Other reasons for the rise in cases include more travel, people spending more time indoors, and a decrease in mask usage. This situation is particularly concerning as the 2024 Summer Olympics in Paris could see a COVID-19 outbreak, given the large number of athletes and spectators gathered in close quarters.
current guidelines : can help keep people safe
Here’s a rephrased version:
Current guidelines can help ensure safety.
“You should stay away from others for at least 24 hours, until your fever subsides without the use of medication like Tylenol and your symptoms start improving,” Gounder advised. However, she recommends taking extra precautions for at least five more days, as that’s when you’re most contagious and likely to spread the virus to others.
Some options for these precautions include:
- Continuing to isolate
- Wearing a mask when around others
- Opening windows for ventilation
- Using HEPA air filtration units to reduce transmission risk
Gounder also emphasizes the importance of using “common sense” regarding COVID testing and precautions.
“If you’re feeling sick, it’s probably a good idea to get tested. And if you’re unwell, try to avoid being around others as much as possible,” she said. Additionally, masks, “despite some opinions, do work to protect you if you’re wearing an N95 or KN95 mask, and they also help protect others if you’re infected.”
