‘Silent spreaders’ may be responsible for half of Covid-19 cases, study finds – CNN
(CNN) Remember “Typhoid Mary” Mallon? She was an Irish immigrant who worked as a cook for New York families and contaminated at least 122 people with typhoid fever in the 1880s, leaving five dead.
Can the AC filter in your home, office or local mall protect you from Covid-19?
As the first known healthy carrier of the bacterial disease, which is transmitted by a toxin in feces, Mallon refused to believe she was an asymptomatic conduit for typhoid fever. She refused to give stool samples to authorities and continued to spread the bacteria via her unsanitary ways until she was caught and quarantined twice for a total of 26 years, dying alone without friends.
