A powerful new Covid strain is capable of re-infecting patients within weeks of them recovering from the virus, doctors from around the world fear.However BA.5 has cast doubt on the notion, with patients reporting falling positive again within a short while of recovering from Covid.Andrew Roberston, chief health officer in Western Australia, told News.com.au : “What we are seeing is an increasing number of people who have been infected with BA.2 and then becoming infected after four weeks.
Immunology professor Danny Altmann, author of a recent paper on the strain wrote in the Guardian how Omicron infections were a “poor booster” of immunities to other Omicron infections. A Lancet study has confirmed for the first time exactly how long we are infectious revealing two thirds of people who catch the virus are still contagious to some extent after five days.
