If You Have This at Home, You May Be More Likely to Get COVID

It may seem like a protective measure against the disease, but it could make things worse, experts say.

While much has been made about air purification techniques potentially helping to mitigate COVID transmission indoors, new research suggests that, in some cases, air purifiers may actually increase the spread of COVID. Read on to discover if what you're doing to protect yourself at home could actually be putting you in harm's way. And for a very different factor that could help keep you safe, check out If You Have This in Your Blood, You May Be Safe From COVID, Study Says.

According to a Jan. 26 study published in the journal Physics of Fluids, air purifiers may actually make the spread of contaminated respiratory droplets in enclosed spaces worse. In the authors' model, which looked at respiratory illness transmission rates in a simulated elevator, they found that while air purifiers do move viral particles, they do little to reduce a virus' transmissibility.

"An air purifier inside an elevator alters the air circulation significantly but does not eliminate airborne transmission," said Dimitris Drikakis, PhD, co-author of the study and a professor at the University of Nicosia, Cyrpus' Medical School and School of Sciences and Engineering.

While a larger number of infected people in a confined space was positively associated with increased transmission rates, air purification methods may still potentially increase the likelihood of new infections, even with low numbers of infected people in a given area.

"Our results show that installing an air purifier may increase the droplet spread," explained Drikakis.

However, using an air purifier isn't the only potentially serious mistake you could be making amid the pandemic; keep reading to discover which other seemingly innocuous behaviors could be putting your health at risk. And if you want to play it safe when you're out and about, beware that Doing This to Your Mask May Make It Protect You Less, Experts Warn.

Driving with the windows up.

If you're in a car with people outside your household, it's important to not only keep a mask on throughout the duration of your trip, but keep the windows open, too. In August, Anthony Fauci, MD, chief medical adviser to President Joe Biden, said, "Even though the person who's driving the car and me both have masks on, I keep the masks on and keep the windows open."

However, opening the window next to you may not be the best course of action. According to a research article published in the Jan. 1 issue of Scientific Advances, researchers found that the most effective way to limit person-to-person transmission inside a car is to have the windows furthest from both the driver and passenger open.

Wearing a vented mask.

While wearing a mask may be essential in terms of stopping the spread of COVID, wearing the wrong type of mask could be putting you in harm's way. According to the Centers for Disease Control and Prevention (CDC), vented masks "may not prevent you from spreading COVID-19 to others. The hole in the material may allow your respiratory droplets to escape." And for more protective measures to avoid, find out why The CDC Warns Against Using These 6 Face Masks.

Whether you're going to work, school, or the grocery store, it's hard for most people to completely eliminate all contact with others. However, just because you're wearing a mask doesn't mean you have carte blanche to see as many people as you'd like. According to a Jan. 2021 study published in JMIR Public Health and Surveillance, individuals who wore masks regularly but had more in-person contact with others were more likely to develop COVID than those who wore masks less frequently, but saw fewer people.

Taking acetaminophen or ibuprofen before your vaccine.

Popping an OTC pain reliever to combat the discomfort associated with your COVID shot may not seem like a big deal, but experts caution against doing so if you want your protection against the virus to last. "We do not recommend premedication with ibuprofen or Tylenol before COVID-19 vaccines due to the lack of data on how it impacts the vaccine-induced antibody responses," Simone Wildes, MD, a member of Massachusetts' COVID-19 Vaccine Advisory Group and an infectious an infectious disease specialist at South Shore Medical Center, told ABC News.
