The Centers for Disease Control and Prevention on Sunday recommended the cancellation of events of 50 or more people for the next eight weeks to try to prevent the spread of the coronavirus.
"Events of any size should only be continued if they can be carried out with adherence to guidelines for protecting vulnerable populations, hand hygiene, and social distancing," the CDC said. "When feasible, organizers could modify events to be virtual."
The guidance does not apply to large organizations such as schools, universities or businesses, the CDC said.
"This recommendation is made in an attempt to reduce introduction of the virus into new communities and to slow the spread of infection in communities already affected by the virus," the agency said. "This recommendation is not intended to supersede the advice of local public health officials."
