There have been reports of 126 House and Senate members infected with or exposed to the coronavirus since last March — 70 Republicans and 56 Democrats, according to data collected by GovTrack.

Why it matters: The data illustrates the infectiousness of the virus and its impact on some of the most powerful and connected people in the country. It does not include Republican Luke Letlow of Louisiana, who died of COVID-19 complications five days before he was to be sworn into Congress in January.
