Notably, several of the new studies find these powerful responses in people who have not developed severe cases of Covid-19, added Dr Iyer. Some researchers worry that infections that weigh less on the body may be less memorable to the studious cells of the immune system, which may prefer to invest their resources in more serious attacks. In some cases, the body might even shed viruses so quickly that it fails to catalog them. “This article suggests that is not true,” Dr. Iyer said. “You can still achieve lasting immunity without suffering the consequences of infection.”

Frequently Asked Questions
Updated August 12, 2020
-
Can I travel to the United States?
- Many states have travel restrictions, and many are taking active steps to enforce those restrictions, such as imposing fines or asking visitors to self-quarantine for 14 days. Here’s an always-up-to-date list of statewide restrictions. In general, traveling increases your chances of catching and spreading the virus, as you are likely to meet more people than if you stayed at home in your own “pod”. “Staying at home is the best way to protect yourself and others from Covid-19,” the CDC says. If you are traveling, take precautions. If you can, drive. If you have to fly, be careful about choosing your airline. But know that airlines are taking real action to keep planes clean and limit your risk.
-
I have antibodies. Am I now immune?
- For now, that seems likely, for at least several months. There have been frightening accounts of people suffering from what appears to be a second episode of Covid-19. But experts say these patients can have a prolonged course of the infection, with the virus taking weeks to months after initial exposure. People infected with the coronavirus usually produce immune molecules called antibodies, which are protective proteins made in response to infection. These antibodies may only last for two to three months in the body, which may sound worrying, but it’s perfectly normal after an acute infection clears, said Dr. Michael Mina, an immunologist at Harvard University. It may be possible to catch the coronavirus again, but it is very unlikely that it will be possible within a short time from the initial infection or making people sicker the second time around.
-
I own a small business. Can I get relief?
- Stimulus bills enacted in March offer help to millions of American small businesses. Those eligible for assistance are businesses and nonprofit organizations with fewer than 500 workers, including sole proprietorships, independent contractors and freelancers. Certain large companies in certain sectors are also eligible. The assistance offered, which is administered by the Small Business Administration, includes the Paycheck Protection Program and the Economic Injury Disaster Loan Program. But a lot of people haven’t seen any payments yet. Even those who have received help are confused: the rules are draconian, and some are stuck on money they don’t know how to use. Many small business owners receive less than expected or hear nothing at all.

What are my rights if I am afraid to return to work?
-
What will school look like in September?
- Many schools are unlikely to return to normal hours this fall, which will require continued online learning, makeshift child care and delayed work days. California’s two largest public school districts – Los Angeles and San Diego – said on July 13 that distance education would only be distance education in the fall, citing concerns that the surge in coronavirus infections in their regions pose too serious a risk to students and teachers. Together, the two districts are home to some 825,000 students. They are the largest in the country to date to abandon plans for a physical return, even partial, to classrooms when they reopen in August. For the other districts, the solution will not be an all or nothing approach. Many systems, including the country’s largest, New York, are devising hybrid plans that involve spending a few days in class and other days online. There is no national policy on this yet, so check back regularly with your municipal school system to see what is happening in your community.
What has been observed in people who have battled mild cases of Covid-19 may not be true for hospital patients, whose bodies struggle to elicit a balanced immune response to the virus, or those who have been infected but who showed no symptoms. Research groups around the world continue to study all of the answers. But “the vast majority of cases are these mild infections,” said Jason Netland, an immunologist at the University of Washington and author of the document under review at Nature. “If these people are to be protected, it is always a good thing.”
This new round of studies could also further allay fears about how and when the pandemic will end. The updated guidelines released by the Centers for Disease Control and Prevention on Friday were misinterpreted by several press reports suggesting that immunity to the coronavirus may only last a few months. Experts responded quickly, noting the dangers of spreading such claims and noting the wealth of evidence that people who have previously had the virus are likely at least partially protected from reinfection for at least three months, if not much longer.
Considered along with other recent reports, the new data reinforces the idea that “Yes, you are developing immunity against this virus and good immunity against this virus,” said Dr. Eun-Hyung Lee, an immunologist at the University. Emory who was not involved. in studies. “This is the message we want to get across.”
Certain illnesses, such as the flu, can affect populations repeatedly. But that’s at least in part due to the high mutation rates of influenza viruses, which can quickly make pathogens unrecognizable by the immune system. Coronaviruses, on the other hand, tend to change their appearance less easily from year to year.
Yet much remains unknown. While these studies suggest the potential for protection, they don’t demonstrate the protection in action, said Cheong-Hee Chang, an immunologist at the University of Michigan who was not involved in the new studies. “It’s hard to predict what’s going to happen,” Dr Chang said. “Humans are so heterogeneous. There are so many factors that come into play. ”
Animal research could help fill in a few gaps. Small studies have shown that an episode of the coronavirus appears to prevent rhesus macaques from contracting it again.
