COVID-19: Epidemiology, virology, and prevention, UpToDate (Updated 27th January 2023)
Coronaviruses are important human and animal pathogens. At the end of 2019, a novel coronavirus was identified as the cause of a cluster of pneumonia cases in Wuhan, a city in the Hubei Province of China. It rapidly spread, resulting in an epidemic throughout China, followed by a global pandemic. In February 2020, the World Health Organization designated the disease COVID-19, which stands for coronavirus disease 2019 [ 2 External 0 0 0 1 false https://www.uptodate.com/contents/covid-19-epidemiology-virology-and-prevention/abstract/1 true false%>]. The virus that causes COVID-19 is designated severe acute respiratory syndr...

Could a popular COVID-19 antiviral supercharge the pandemic?
A widely used COVID-19 drug may be driving the appearance of new SARS-CoV-2 variants, sparking concerns it could prolong and even reinvigorate the pandemic. The drug, molnupiravir, produced by Merck & Co., is designed to kill the virus by inducing mutations in the viral genome. A survey of viral genomes reported in a new preprint, however, suggests some people treated with the drug generate novel viruses that not only remain viable, but spread. “It’s very clear that viable mutant viruses can survive [molnupiravir treatment] and compete [with existing variants],” says virologist William Haseltine, chair of A...

COVID-19 Is No Longer a Public Health Emergency
A month before his recent retirement, Dr. Anthony Fauci cautioned that the U.S. “certainly” remains in the midst of a COVID pandemic. Other experts repeatedly warn of impending “deadly” waves caused by the latest genetic variants, and recently President Biden once again extended the COVID-19 Public Health Emergency. Yet those dire warnings hinge largely on an assumption that some 400 people in the U.S. continue dying daily from the disease. There are important reasons to question this assertion, as Dr. Leana Wen explored in the Washington Post. And if therefore in fact we’re no longer in a pub...

Data Doesn ’t Support New COVID-19 Booster Shots for Most, Says Vaccine Expert
In a perspective published Jan. 11 in the New England Journal of Medicine, vaccine expert Dr. Paul Offit says it’s time to rethink booster recommendations. In the third year of the pandemic, the population’s immune situation is vastly different from what it was in 2019 when SARS-CoV-2 emerged. Now, most people have been vaccinated against the virus, been infected with it (once or multiple times), or both. And the latest data show that the newest booster shot, which targets the Omicron BA.4/5 strain and original virus variants in a bivalent formulation, isn’t that much more effective in generating virus-fi...

Africa: Where Is the Next Covid Variant, Pi? a Virologist Explains Why Omicron Is Continuing to Dominate
[The Conversation Africa] The omicron variant of SARS-CoV-2, the virus that causes COVID-19, has now been around for more than a year. Before omicron became dominant, there had been a quick succession of named variants of concern - from alpha, to beta, to gamma, to delta. But now it seems as though we're facing a never-ending string of letter and number combinations denoting the children and grandchildren of omicron: BA.2, BA.2.75, BA.5, BQ.1, BF.7, XBB - the list goes on.

Armed with air samplers, rope tricks, and —yes—ants, virus hunters spot threats in new ways
On a Friday morning in September last year, Erik Karlsson visited the sprawling Orussey market here, where vendors hawked pots and pans, phone cords and radios, hats and dresses—and myriad types of Southeast Asian food. Dozens of orange-colored, whole roasted pigs hung on hooks, crabs the size of two fists filled buckets, and stacked fruit and dried fish formed mountains on tables. Karlsson had come for the live poultry, but not because he was planning a dinner. As an epidemiologist at Cambodia’s Pasteur Institute, he was hunting for potentially dangerous pathogens, both known and unknown. He had nothing with him...

Eleven science stories likely to make big news in 2023
As the COVID-19 pandemic enters its fourth year as a global health emergency, researchers will continue pushing to help make the disease manageable and ordinary. They will track hundreds of subvariants of Omicron, the highly transmissible but seemingly less lethal strain of SARSCoV-2 that dominated in 2022. Virologists will watch the virus’ evolution this year to see whether it has finally slowed or a more dangerous variant pops up, evading much of the immunity that humanity has built up to previous ones. Vaccine researchers hope to develop new shots that provide broad protection against a variety of coronaviruses. Ano...

China is flying blind as pandemic rages
Most scientists believe China’s decision to end its zero-COVID policy was long overdue. But now they have a new worry: that the country is collecting and sharing far too little data about the rough transition to a new coexistence with the virus. China abruptly dropped virtually all controls a month ago, after protests, a sagging economy, and the extreme transmissibility of the virus’ latest variants made clinging to zero COVID untenable. Now, “SARS-CoV-2 has an open goal in front of it: a population with very low levels of standing immunity,” says evolutionary biologist Edward Holmes of the University of Sydn...
