New research shows that Covid-19 antibodies can neutralize the virus and last up to five months

There’s encouraging news about antibodies in a new paper published in the journal Science from researchers at New York City’s Mount Sinai Hospital. In their study of the antibody responses of patients with either mild or moderate Covid-19, antibody levels appeared to stay relatively stable for at least five months, and their presence was correlated with the inactivation of the virus.

Antibodies are molecules pumped out by the immune system in response to infection, and they have a role in preventing future infections, though exactly how they function within the context of Covid-19 isn’t clear yet. Scientists are urgently trying to figure out whether the presence of antibodies actually means a person is protected from future infection as well as how long antibodies last in the body. Knowing this is crucial, especially for vaccine development.

Death Rates Have Dropped for Seriously Ill Covid Patients

The coronavirus struck the United States earlier this year with devastating force. In April, it killed more than 10,000 people in New York City. By early May, nearly 50,000 nursing home residents and their caregivers across the country had died.

But as the virus continued its rampage over the summer and fall, infecting nearly 8.5 million Americans, survival rates, even of seriously ill patients, appeared to be improving. At one New York hospital system where 30 percent of coronavirus patients died in March, the death rate had dropped to 3 percent by the end of June.

Internal Documents Reveal COVID-19 Hospitalization Data The Government Keeps Hidden

As coronavirus cases rise swiftly around the country, surpassing both the spring and summer surges, health officials brace for a coming wave of hospitalizations and deaths. Knowing which hospitals in which communities are reaching capacity could be key to an effective response to the growing crisis. That information is gathered by the federal government — but not shared openly with the public.

NPR has obtained documents that give a snapshot of data the U.S. Department of Health and Human Services collects and analyzes daily. The documents — reports sent to agency staffers — highlight trends in hospitalizations and pinpoint cities nearing full hospital capacity and facilities under stress. They paint a granular picture of the strain on hospitals across the country that could help local citizens decide when to take extra precautions against COVID-19.
