Abstract: A system may include various user devices coupled to a cellular network. Each user device may be associated with a respective member of a predetermined population. The system may further include a contact management server coupled to the cellular network. The contact management server may determine a previous contact event of a user device among the user devices. The contact management server may further determine a selection of a first contact type for contacting the user device. The first contact type may be different from a second contact type of the previous contact event. The contact management server may further transmit a command that triggers the contact event of the user device based on the first contact type.

Abstract: A method may include determining whether to perform a coronavirus diagnostic test on a member of a predetermined population. The method may further include sending, in response to determining that the coronavirus diagnostic test should be performed on the member, a coronavirus testing kit to the member. The coronavirus testing kit may include a return shipping container, a substrate, and a specimen transport container configured to store a biological specimen. The method may further includes determining whether the biological specimen is received at a laboratory facility from the member. The method may further include transmitting, to at least one user device associated with the member, a notification regarding a coronavirus infection diagnosis based on the biological specimen.
