If someone in your household has COVID-19, there is only a 1 in 10 chance that you will get it too, according to a study
- Researchers in Boston studied more than 7,000 homes with a Covid case
- He found that, of all the people who lived with them, only 10.1% were infected
- The study also found that the risk of contracting at the home of someone you live with increases for people with pre-existing health problems
According to one study, only one in ten people who catch Covid passes it on to someone they live with.
American researchers analyzed data from more than 7,000 homes in Boston and found that more than 25,000 people lived there between March 4 and May 17, 2020.
In that period, 7,262 people took Covid, but only transmitted it to 1,809 other people with whom they lived, a transmission rate of 10.1 percent.

The newspaper also found that the likelihood of transmitting the virus to someone you live with was lower in larger households.
For example, someone in a house with three to five people – one of whom was infected – was at 20 percent less risk than a house for two.
However, the data showed that people living with Covid’s products are more likely to contract the virus from an infected family member.
People living with Covid products are more likely to contract the virus from an infected family member. The risk of contracting the virus increases by 31 percent if a person has asthma
The risk of contracting the virus increased by 31 percent if a person had asthma, 67 percent for cancer patients and 35 percent if a family member was obese.
However, the likelihood of infection has more than doubled for people with liver disease.
“Independent factors significantly associated with increased risk of transmission include age over 18 and multiple comorbidities,” wrote the Massachusetts General Hospital researchers in their study, published in the JAMA Open Network.
The findings support other research that found a similarly low secondary attack rate of the virus in homes.
A review of 54 studies also published in the JAMA Network Open in December 2020 found a home transmission rate of 16.6 percent.
A new study by Canadian public health officials published as a prepress on medRxiv found that for all of Ontario between July 1 and November 30, 2020 the rate was only 19.5 percent.
