Seattle COVID ranks third in world after patient recovery

Doctors say a patient in the Seattle area is confirmed to be reinforced with COVID-19, the only documented case in the world. Researchers at the Swedish Medical Center in Seattle are studying whether reassignment can tell them how long immunity lasts, and how effective the vaccine can be.

The only documented second infections were a 35-year-old man in Hong Kong and a 25-year-old man in Reno, Nevada.

Dr. who led the COVID research team at the Swedish Medical Center. Jason Goldman said, “We don’t know how many immunity levels we need to protect.”

In the Seattle case, patients were living in a nursing facility in their 60s and hospitalized after being infected for the first time.

After about 140 days, the patient developed very mild symptoms after being infected for a second time, and Goldman said this was encouraging news.

“Most of the reported cases are more mild around the second time,” he said. “Even if the immune system fails to prevent a second infection, it appears to limit severity at other times.”

Goldman said that it appears that your body’s antibodies develop with one infection, work for the majority of the time, and another risk can make it easier.

“The majority of patients infected with COVID have become re-infected and not re-infected, so this is another reassuring finding.”

Goldman’s study can help the world understand how long COVID-19 antibodies last. Every case of second infection occurred at least once a year after recovering from the first infection.

“In most cases there were four or more months from the first transition to the second, so maybe it could be a inflection point,” he said. “Our immunity (maybe) then starts to go in vain, but we really don’t know yet.”

Goldman said there is a slightly different strain from coronovirus originating from Wuhan, China in January, and future studies will help to find out how our immune system has to react to be safe.

The vaccines currently being tested are based on China’s original COVID-19 virus. But the most prevalent global circulating stress is slightly different. The various strains are called “D6-14G” and may be more infectious than the original virus.

“We still have a lot about this virus and immunity that we need to protect ourselves from,” he said.
