Living with someone who has COVID-19 increases your risk of catching the disease, even if you are fully vaccinated, according to international research. The team studied health care workers in Israel and found that compared with exposure to COVID-19 at work, living with a family member who had COVID-19 was a higher risk factor for catching the disease. The team say this is likely due to being exposed for a longer and closer time period without masks or social distancing, and therefore exposure to a higher infectious dose.

What The Study Did: This case-control study found that exposure to SARS-CoV-2-positive household members was a risk factor associated with infection among vaccinated health care workers. Household exposure is usually longer and closer than casual exposure or exposure at work and does not include masking or distancing, thus exposing one to a higher infectious dose and being more contagious.
