TWiV reviews the FDA decision to update COVID-19 vaccine boosters in the fall, the meaning of fatigue with respect to long COVID, and a skin volatile induced by flavivirus reproduction that attracts mosquitoes to the infected host.
TWiV summarizes cases of arbovirus disease during 2019 in the US, and explains a study that estimates infectiousness throughout the SARS-CoV-2 course of infection.
