The uptick is because of former vice president joe bidens administrations policy regarding illegal aliens. We are averaging 180,000 border crossers EVERY month. (2+ million a year).
None of these persons are tested for anything and they are then shipped all over the country. Not just to one place so the diseases spread in a way that the government "cant explain, so we need more lock downs, masks, and vaccines".
And the illegals arent just bringing covid. They are bringing all sorts of third world diseases. TB, polio, etc. Hell even dengue fever has been reported. Just wait till one of the africans (who enter via Mexico) bring Ebola.
