Although the exact length of immunity after COVID-19 infection is not yet determined, it is certainly possible re-infection may occur. Given this variation, there is ongoing research to determine if the virus that causes COVID-19 will behave more like MERS or more like the common cold.Įxperts caution that immunity from a viral infection is a complex, multifold process. Other types of coronavirus – such as the Middle Eastern Respiratory Syndrome, or MERS virus – may, however, result in several years of immunity. For several of the common cold causing coronaviruses, prior infection might protect you for about six to 12 months. The novel coronavirus, or SARS-CoV-2, belongs to a large family of coronaviruses that are known to cause illnesses varying from the common cold to severe infections such as severe acute respiratory syndrome, or SARS.īased on research from other coronaviruses, experts say there is a wide range in how long immunity lasts after an initial infection. In theory, given a long enough time after recovery, re-infection is “plausible,” he said. Todd Ellerin, director of infectious diseases at South Shore Hospital.
“The duration of immunity is unclear, but it does make sense that we may start seeing cases of re-infection with the novel coronavirus, as with other common coronavirus infections," said Dr.
