Though many monoclonal antibodies were paused after demonstrated to be insufficient against the BA.1 Omicron subvariant, they may be more effective against BA.2.

A systematic review of clinical trials found a high probability that fluvoxamine prevented COVID-19 hospitalizations in outpatient settings.

The risks of deep vein thrombosis, pulmonary embolism, and bleeding events were increased at 3 or more months after COVID-19 infection.

After the US Food and Drug Administration (FDA) fully authorized the Pfizer-BioNTech mRNA vaccine, series-completing second doses increased substantially. However, first vaccine doses were actually administered at lower rates after the approval.

Bedaquiline-resistant tuberculosis is characterized in South Africa, where it has not been reserved as last resource for drug-resistant TB.

Being displaced by war is causing a disruption in treatment and long-term health care for Ukrainians. And it is likely, the situation will become more dire as the country’s public infrastructure worsens.

Notoriously slow to implement new practices, most hospitals rapidly updated their standard treatment procedures during the COVID-19 pandemic.

Children under 5 became infected with the Omicron variant 6-8 times more frequently than young children who contracted Delta. However, Delta COVID-19 infections were more severe than Omicron.

Despite lower comorbidity risk scores than Black or White COVID-19 patients, Mississippi’s Indigenous populations had significantly higher in-hospital mortality rates.

One day after the FDA approved second booster shots for certain vulnerable populations, the National Institute of Health (NIH) announced they have begun enrolling adult US participants in a phase 2 clinical trial to evaluate a second COVID-19 booster dose.

2 doses of the Pfizer-BioNTech vaccine reduced Omicron hospitalizations by 68% in children 5-11 and by 40% in adolescents 12-18 years old.

“Together these 2 diseases create a perfect storm”: Black people with cancer were more likely to have severe or fatal COVID-19 disease.

The World Health Organization updated its guidelines for the treatment of nonsevere tuberculosis in children after a study showed a four-month duration was noninferior to six months.

The coronavirus pandemic caused the first global recorded decline in human life expectancy.

The Assistant Secretary for Preparedness and Response (ASPR) announced a pause in sotrovimab distribution in regions where BA.2 is the dominant COVID-19 variant, citing evidence that the monoclonal antibody therapy would not effectively neutralize the BA.2 Omicron variant.

A matched cohort study found COVID-19 infection increased the risk of new type 2 diabetes diagnosis. Compared to patients with acute upper respiratory tract infections, COVID-19 patients were 28% more likely to develop diabetes.

There are many unknowns about the BA.2 COVID-19 variant. It appears 50-60% more transmissible than the original Omicron variant, but health experts are mixed on whether cases will spike dramatically.

A Texas study found children and adolescents who previously contracted COVID-19 retained protective antibodies for 6 or more months after infection. However, natural infection plus vaccination remains the best defense against COVID-19.

In children and adolescents, the Pfizer-BioNTech vaccine was only mildly effective against symptomatic and asymptomatic COVID-19 infections. Broken down by variant, Omicron infections were more likely to occur and more likely to be asymptomatic.

Axcella Therapeutics chief medical officer Dr. Margaret Koziel discusses the stage 2a clinical trial for their novel long covid treatment.

The new COVID-19 sub-variant, called “Deltacron” or “Stealth Omicron,” appears to be the most contagious strain yet. However, this does not necessarily mean there will be a dramatic spike in cases.

Findings of JAMA Network Open analysis reveal effects of interventions designed to prevent spread.

“Deltacron,” a COVID-19 strain with genes from both the Delta and Omicron variants, appears to have been circulating since the beginning of the year.

The war on Ukraine is expected to drive COVID-19 and other infectious diseases, meaning health organizations and neighboring countries should prepare to assist in the impending health crises.

Even a mild COVID-19 infection can change the brain. People infected had a greater reduction in brain volume and performed worse on cognitive tests than those who did not contract COVID-19.

Associations between social determinants of health (SDOH) and COVID-19 mortality varied across racial and ethnic groups and community types.

One study found people were more likely to take the COVID-19 pandemic seriously when they saw the overall number of infections, as opposed to being presented with only new daily cases.

Minnesota hospitals established to care exclusively for COVID-19 patients saw lower rates of mortality than general hospitals.

A single-dose injection of nirsevimab before RSV season was proven to reduce infants’ risk of lower respiratory tract infection by 74.5%.

“COVID-19 need no longer control our lives,” President Biden said, detailing a plan to immediately provide free antiviral pills to anyone who tests positive.
