(CNSNews.com) – Dr. Anthony Fauci, director of the National Institute for Allergy and Infectious Diseases, told Congress on Wednesday that it “happens all the time with infections” where “a person’s natural resistance” to COVID-19 can prevent them from contracting the virus after prolonged exposure to someone who tests positive.
At a Senate H.E.L.P. Committee hearing providing an update on the federal response to COVID-19, Sen. Richard Burr (R-N.C.) asked Fauci to address the scenario of a married couple that lives together and the husband tests positive for the coronavirus but the wife never tests positive for it.
“Would you also answer for members of Congress, for the husband and wife that come to us and say my husband got COVID and I, the wife, didn't get it, how would a highly transmittable infection like this can two people live together and one be positive and one never get positive?” Burr asked.
“That happens all the time with infections, Senator. Although a virus can be highly transmissible, there is a great degree of variability of a person's natural resistance to a particular type of an infection. So although a highly transmissible virus usually as an attack rate that's high, we see all the time individuals who are exposed to someone with an infection who do not get the infection,” Fauci said.
“If you look at the population as a whole, you see the kinds of things that we're seeing as this pandemic evolves that it is highly contagious,” he said.
“We had the same situation where you had HIV where individuals were living with a person who had sex on a regular basis with someone with HIV and they never got infected, whereas another person could have sex one time with a person with HIV and get infected. That's the nature of the variability of susceptibility to infection among individuals so it's entirely conceivable,” Fauci added.
