This thing seems really fucking contagious:
Most cases linked to the meeting, which was attended by about 175 people, are in Massachusetts. State health officials said Monday that 32 of the 41 infected patients in the state were either Biogen employees or close contacts of employees.
Two people in Indiana, five people in North Carolina and one person in New Jersey tested positive with coronavirus after attending the meeting.
Biogen has since informed all attendees to quarantine themselves and symptomatic employees to alert public health officials, the company said in a statement emailed to The Washington Post.
“We recognize that this is a difficult situation for our colleagues and their loved ones,” the drugmaker wrote. “We are actively working with all relevant departments of public health and hospitals to prioritize the well-being of the people who may have been exposed to COVID-19.”

Unclear how many of the 32 in Massachussets were there, but it seems like a quarter of the people catching something from one conference is bad. It's supposed to be less contagious than the flu. Does the flu transmit like that?
