Alternatively, if a 5-day quarantine is not feasible, it is imperative that an exposed person wear a well-fitting mask at all times when around others for 10 days after exposure. Individuals who have received their booster shot do not need to quarantine following an exposure, but should wear a mask for 10 days after the exposure. For all those exposed, best practice would also include a test for SARS-CoV-2 at day 5 after exposure. If symptoms occur, individuals should immediately quarantine until a negative test confirms symptoms are not attributable to COVID-19.
Ford spoke at a virtual event that was part of Harvard Chan School’s Population Mental Health Forum Series, hosted by Karestan Koenen, professor of psychiatric epidemiology. She also noted that some kids who were already struggling with emotional issues actually seemed to do better during the pandemic. Job losses have left families struggling to pay for necessities like housing, food and medical care, while those who are still employed report difficulty finding child care.

The NSF program officer at the time questioned whether the proposed work was relevant for the nation, an important criterion for selecting grants to fund, but after the very first cases of COVID-19 were detected locally in Santa Clara County, they agreed to fund our proposal. These daily samples from the Codiga sewershed, an area covering more than 150 buildings and 10,000 people on campus, provide clues about the rise and fall of the virus’ prevalence on campus, often several days ahead of the trends identified by the university’s testing program. While there is no overall data yet on exemptions for COVID-19 vaccines, a number of companies and state governments have seen interest in religious exemptions — a protection stemming from the Civil Rights Act of 1964. This leaves employers in the difficult and legally precarious position of determining whether the requests are valid. As such, some states have tried to do away with non-medical exemptions overall for their employees.
Will there be new variants of COVID-19?
Variants Are Expected. Some variants emerge and disappear while others persist. New variants will continue to emerge. CDC and other public health organizations monitor all variants of the virus that causes COVID-19 in the United States and globally.
The new research also aligns with a 2020 study that found that hormone replacement therapy cut the Covid fatality risk in half among women over 50. That research did not, however, find a difference among pre-menopausal women. A 2016 laboratory study, for instance, suggested that estrogen prevented the influenza virus from replicating in cells. And other research has shown that estrogen may prevent HIV, Ebola and hepatitis from replicating as well.

Mary Bushman, postdoctoral research fellow in the Department of Epidemiology and co-author of a recent paper that modeled the impact of hypothetical variants on populations, answered questions about the latest variant, Omicron. The Moderna vaccine is slightly better than the Pfizer vaccine, according to a recent Harvard Chan School study. Stephen Kissler, research fellow in the Department of Immunology and Infectious Diseases, is expecting a “surge within a surge” this winter as the Omicron variant of SARS-CoV-2 spreads along with the already-surging Delta variant. Catherine Arsenault, research scientist in the Department of Global Health and Population, discussed her research about the resilience of health systems during the COVID-19 pandemic. Experts say that COVID-19 will eventually become endemic, which Stephen Kissler, research fellow in the Department of Immunology and Infectious Diseases, defined as “some sort of acceptable steady state” in which the coronavirus continues to circulate much like the flu. Dean Michelle Williams was one of the more than 200 leading U.S. doctors and scientists who signed an open letter in support of Anthony Fauci, who has been the subject of Republican attacks.
The White House says 78% of adults have now gotten at least one dose of a COVID vaccine, and there is a push to boost vaccinations ahead of what’s expected to be a busy holiday travel season. United Airlines says it plans to fly 3,500 domestic flights in December every single day. The CDC is also reminding Americans to get their flu shots, saying it will help reduce strain on already overwhelmed hospitals.
Karestan Koenen, professor of psychiatric epidemiology, said that pandemic-related school closures have been tough on tweens and teens, many of whom now lag developmentally in terms of how to act with peers. She also noted that reconnecting with friends can be stressful because people have different risk tolerances for togetherness. Partnerships with schools and community groups plus more supports for children and families are needed to help youths impacted by the pandemic that has stretched on for a year.
Can you contract COVID-19 through sexual intercourse?
Although there is currently no evidence that the COVID-19 virus transmits through semen or vaginal fluids, it has been detected in the semen of people recovering from COVID-19. We would thus recommend avoiding any close contact, especially very intimate contact like unprotected sex, with someone with active COVID-19 to minimize the risk of transmission
In a Q&A, Kizzmekia Corbett, assistant professor of immunology and infectious diseases—one of USA Today’s Women of the Year—talked about her role in COVID-19 vaccine development and her efforts to answer questions about her work with community and national organizations. Sept. 1, 2021 – Project Firstline is a comprehensive training program led by the CDC to prevent the spread of infectious diseases in U.S. health care settings. Sept. 17, 2021 – A federal advisory panel unanimously recommended approval of a booster dose of Pfizer’s COVID-19 vaccine for people 65 years and older and those at increased risk of severe disease.
