Contact support: Educate, inform, and support exposed persons about their risk, steps to protect others, and to watch for sickness illness.
Self-quarantine: Contacts are encouraged to stay home and maintain social distance from others until 14 days after their last exposure to the infected patient, in case they also become ill.
