Immunity persisted for several months after being infected with SARS-CoV-2, the virus that causes COVID-19, stated new research.
Coronavirus
Coronaviruses infect animals, humans, and birds. Human coronaviruses, such as SARS, MERS, and 2019-nCoV cause respiratory distress and even death. The S protein is the infectious agent of the virus.

‘People who were infected with the first SARS coronavirus, which is the most similar virus to SARS-CoV-2, are still seeing immunity 17 years after infection.’
"We clearly see high-quality antibodies still being produced five to seven months after SARS-CoV-2 infection," said study author Deepta Bhattacharya from the University of Arizona in the US. When the virus first infects the cells, the immune system deployed short-lived plasma cells. The plasma cells produce antibodies to fight the virus that causes COVID-19. These antibodies appeared in the blood tests within 14 days of infection.
During the second stage of the immune response, long-lived plasma cells are created—these plasma cells produced high-quality antibodies that provide lasting immunity.
Coronavirus Facts from Autopsy Reports of COVID-19 Patients
Autopsies onCOVID-19 patients reveals a lot of information on the virus. There have been no reports of COVID-19 transmission between a corpse and a pathologist.

"The latest time-points we tracked in infected individuals were past seven months, so that is the longest period of time we can confirm immunity lasts," Bhattacharya said.

How Has COVID-19 Impacted Use of Telehealth Visits?
Older adults are increasingly comfortable with telehealth, especially in 2020, due to the COVID-19 pandemic. Telehealth is an effective means for older adults to access health care from the safety of their own homes.
