The Massachusetts Department of Public Health has informed the Belmont Health Department that two more residents have been declared “presumptive positive” for the COVID-19 virus, according to an email dated Friday, March from Wesley Chin, director of the Health Department.

Belmont now has a total of three MDPH confirmed cases of the stain of the Coronavirus which has developed in just four months into a global pandemic. As of March 13, there are 123 cases In Massachusetts.

MDPH defines “presumptive positive” as a person that has tested positive by the Massachusetts State Public Health Laboratory, while awaiting specimens sent to the US Centers for Disease Control for final verification.

Like the initial case, these residents are linked to the Biogen conference held in Boston at the end of February. Statewide 82 out of 108 positive cases are linked to the Biogen event that took place at the Boston Marriott Long Wharf Hotel.

The first person who contracted the virus is currently in isolation in their home, staying away from their family members who are self-quarantined in the same location for 14 days.

“Other members of the family, do not have symptoms of COVID-19,” said Chin.

“Local health departments, including the Belmont Health Department, conduct contact investigations of confirmed and presumptive positive COVID-19 cases, in collaboration with MDPH. This helps to prevent further spread by having contacts of cases self-quarantine,” read the email.
