I recovered from COVID a week ago. If I am exposed again tomorrow (possibly to a different variant), can I become infectious for a period of time?
There may be some short duration of immunity from a next Covid infection with your recent infection. However, some people have been observed to get repeated Covid infections, due to continued high-level exposure, on a nearly month basis. Therefore, if you continue to allow yourself to be exposed to Covid infected persons, then I would expect that you could become infected in about a month. Repeated infections may be associated with milder symptoms but do not necessarily change your risk/severity of developing Long Covid (post-acute sequelae of SARS-CoV-2 infection). The best course of action is to try and reduce your exposures to Covid.
