Mandatory isolation for infected individuals? Farvel.

The 1918 flu didn’t end in 1918. Here’s what its third year can teach us. – Washington Post

In New York City in 1920 — nearly two years into a deadly influenza pandemic that would claim at least 50 million lives worldwide — the new year began on a bright note. Within a few weeks, however, those optimistic headlines began to change. Before the end of the month, New York City would experience a surge in influenza cases. Chicago and other urban centers reported the same.

The future of the pandemic is looking clearer as we learn more about infection – NPR

During the early days of the pandemic, scientists and doctors were concerned that being infected with SARS-CoV-2 might not trigger a strong immune response in many people – thus an infection might not provide long-term protection.

Vaccine Headlines

Will Covid-19 Vaccine Nasal Sprays Be the Pandemic Game-Changer We Need? – Rolling Stone

Promising results from a study at Yale University are still undergoing peer-review — but offer hope for managing Covid-19 in the future. The best Covid-19 vaccines are really, really effective. Better than many flu vaccines. Better than some hepatitis-B vaccines. Better than the measles vaccines, in many cases.

Study suggests Omicron-specific booster may not provide more protection – STAT

The work, by scientists at the National Institutes of Allergy and Infectious Diseases’s Vaccine Research Center, shows that animals boosted with the original vaccine had similar levels of protection against disease in the lungs as did primates that received an updated booster based on the Omicron strain. The work was done with Moderna’s licensed vaccine and a booster shot based on the Omicron variant.

Clinical Considerations

NIH-funded study suggests COVID-19 increases risk of pregnancy complications – NIH

Pregnant women with COVID-19 appear to be at greater risk for common pregnancy complications — in addition to health risks from the virus — than pregnant women without COVID-19, suggests a study funded by the National Institutes of Health. The study, which included nearly 2,400 pregnant women infected with SARS-CoV-2, found that those with moderate to severe infection were more likely to have a cesarean delivery, to deliver preterm, to die around the time of birth, or to experience serious illness from hypertensive disorders of pregnancy, postpartum hemorrhage, or from infection other than SARS-CoV-2. They were also more likely to lose the pregnancy or to have an infant die during the newborn period. Mild or asymptomatic infection was not associated with increased pregnancy risks.

New conditions common 1 to 5 months after positive COVID test – CIDRAP

A cohort study of Americans tested for SARS-CoV-2 infection shows that new-onset shortness of breath, heart rhythm abnormalities, and type 2 diabetes were more common 31 to 150 days after testing positive for COVID-19 than among those with negative results.

High risk of death or readmission after COVID-19 hospitalization – MedNewsToday

A new study finds that being released from the hospital after receiving treatment for COVID-19 does not guarantee survival. “This won’t be entirely due to lasting effects of the virus — we know that COVID-19 picks on more vulnerable people in the first place, plus there are generic adverse consequences of being seriously ill and hospitalized. Hence, the risks were more similar when we compared [them with those for] hospitalized flu patients.”

U.K. Expert Group Attempts to Define ‘Long COVID’ in Kids – MedPageToday

A standardized research definition of so-called “long COVID” in children was reached by a panel of clinicians, researchers, and patients to complement the existing World Health Organization (WHO) definition of long COVID for adults.

COVID Smell Loss and Long COVID Linked to Inflammation – Scientific American

An impaired sense of smell affects from about 30 to 75 percent of people infected with the novel coronavirus, according to a recent estimate, suggesting that millions of people worldwide have suffered this condition at some point in the past two years. Called anosmia, the olfactory system dysfunction is typically temporary, but it can take months or longer for a full recovery, making it difficult to enjoy meals and to detect odors such as spoiled food, smoke and others that can signal danger.

New Antiviral Drug Combination Is Highly Effective Against SARS-CoV-2, Penn Study Finds – Penn Medicine

Researchers have identified a powerful combination of antivirals to treat COVID-19. Combining the drug brequniar with remdesivir or molnupiravir — both approved by the U.S. Food and Drug Administration for emergency use — inhibited the SARS-CoV-2 virus in human respiratory cells and in mice, according to a new study led by researchers in the Perelman School of Medicine at the University of Pennsylvania and the University of Maryland School of Medicine. The findings, published this week in Nature, suggest that these drugs are more potent when used in combination than individually.
