Is Omicron Subvariant BA.5 Causing More COVID-19 Reinfection Cases?

As President Biden announces he tested negative for COVID-19, more cases continue to rise in the U.S. In New York, hospitalizations are up 70% from June with many of the new cases being reinfections. Doctors are warning that you could get reinfected with a COVID variant every month due to natural immunity waning quickly. At San Diego Comic-Con, guests had to show proof of vaccination or a negative COVID test and wear masks. One guest of honor still tested positive after attending the event.
