This Is the Person Who Is Most Likely to Give You COVID, Study Finds

A new study says there's one person specifically getting others infected.

We've spent most of the past nine months fearful of the outside world and considering home one of our only safe havens. But with household transmission of coronavirus becoming one of the most common ways the virus spreads, that reality is changing. Now, it's not someone at the grocery store or a colleague who's most likely to spread COVID to you. According to a new report, the person most likely to give you COVID is your spouse.

The new meta-analysis out of the University of Florida, which was published in the journal JAMA Network Open on Dec. 14, is based on 54 studies that span 20 countries and nearly 78,000 subjects. According to the researchers' findings, in more than one in three cases—about 37.8 percent—patients passed COVID on to their spouses. "Infection risk was highest for spouses, followed by non-spouse family members and other relatives, which were all higher than other [close] contacts," the authors wrote.

While anyone living under the same roof could potentially spread coronavirus amongst their housemates, the study points out that spouses are more likely to infect one another with COVID due to a variety of factors: "intimacy, sleeping in the same room, or longer or more direct exposure to index cases," according to the report's authors.

But they're less likely to pass COVID-19 on to children they live with.

Overall, the researchers found that 16.6 percent of all people with COVID-19 in the studies they analyzed passed the virus on to members of their household. But, compared to the high rate of COVID transmission between spouses, only 16.8 of positive COVID patients transmitted the virus to the children they live with.

Those with symptoms were more likely to spread the virus.


The study also found that those who showed symptoms passed COVID-19 on to members of their household 18 percent of the time, whereas patients who showed no signs of being sick spread the virus to just 0.7 percent of their household contacts.

You're more likely than not to catch the virus from someone you live with.

Keeping yourself protected from coronavirus is one thing while in public, but it can be significantly harder to keep up efforts when you're lulled into a sense of safety by being in your home. Unfortunately, a recent study by the Centers for Disease Control and Prevention (CDC) found that 53 percent of people who lived with someone infected by the novel coronavirus caught the disease within seven days.

You need to establish a plan to protect yourself from infection at home.

It might be easy to avoid large crowds and wear your face mask in public, but things take on a different level of difficulty when you're forced to use your living room with the same precautions you would during a trip to the grocery store. Still, experts recommend isolating yourself from anyone who's sick to the best of your abilities, and to designate one lower-risk person to care for them using extra steps to keep themselves safe.

"You can have a healthy person leave the sick one food and drinks at the door, and then go wash their hands," Tanya Altmann, MD, told CNN. "Wear gloves to pick up the empty plates, take them back to the kitchen and wash them in hot water with soap, or preferably with a dishwasher, and wash your hands again."

Looking to lower your risk even further? "I'd keep windows open in all shared spaces," Leana Wen, MD, an emergency physician, told CNN. "Also, an air purifier with a HEPA filter could help. So would a humidifier, as viruses linger longer in dry air—especially in the shared space."

Wearing a mask at home can go a long way.

Even though being able to take off your mask when you walk in your front door feels like a relief, keeping it on around the house could be the key between getting sick and staying healthy. One recent study even found that donning a face covering is 79 percent effective in stopping the spread of COVID-19 to other members of a household when they were put to use before someone became fully symptomatic.

But this kind of situation also means that everyone at your address will have to fully quarantine to stop the spread outside the household. "I would recommend that families find friends who can drop off essential groceries or medications, not go to work, and not play with other children—even outside," Jenny Radesky, MD, a spokesperson for the American Academy of Pediatrics, told CNN.
