Seattle Patient Has Second COVID Infection

– For the third time in a row, a COVID-19 survivor has contracted a second coronavirus infection. The man, who is in his 60s, was hospitalized after the first infection, was living in a nursing facility, KIRO reports. After more than four months, the patient had mild symptoms. “Most of the reported cases are mild the second time,” said Drs. Jason Goldman, head of the COVID Research Team at Sweden Medical Center in Seattle. “So even though the immune system fails to prevent secondary infection, it seems to limit the severity a second time.”

; Other recorded cases of secondary infection with COVID-19 involved a 35-year-old man in Hong Kong and a 25-year-old man in Reno.

A team at the medical center is trying to understand what the case means about immunity and vaccines. “We don’t know how many levels of immunity we need to protect,” Goldman said, per KIRO. If this coronavirus acts the way others do, per Scientific American, disinfection will become more common. Antibodies developed in the body to fight the first infection appear to make the second infection worse, Goldman said. “Most cases have four or more months from the first infection to the second, so that could be a point of inflation perhaps,” he said. “Our immunity (may) start to weaken then, but we don’t really know that yet.” Vaccines in today’s works are designed to fight the original virus, but there are various strains that infect people today.
