A scientific literature review for empiric examples of impacts from 10 climate hazards influenced by greenhouse gas emissions found that more than 58% of human diseases caused by pathogens—such as dengue, pneumonia, and Zika virus—are made worse by the climate-related hazards. A team based at the University of Hawaii at Manoa reported the findings today in Nature Climate Change.

COVID-19 patients early in the pandemic had 4% higher healthcare use in the 6 months after illness onset than matched controls, most notably for infection-related conditions, hair loss, bronchitis, pulmonary embolism or deep vein thrombosis, and shortness of breath, finds a study today in JAMA Network Open.
Following the Food and Drug Administration (FDA) emergency use authorization (EUA) of the Novavax COVID-19 vaccine last month for the primary vaccine series, the company announced today that it has applied for an EUA for the vaccine to also be used as a booster in adults ages 18 and older.
A study of more than 2,900 healthcare workers (HCWs) shows that those who wore a respirator were more than 40% less likely to be infected with COVID-19 than those wearing a surgical mask.
Using a test-to-stay (TTS) strategy in K-12 schools during the winter of 2021-22 resulted in substantial reduction in missed school days, according to a study yesterday in Pediatrics.
A new study offers a complex picture of COVID-19 incidence among the US homeless population and illustrates the difficulty of tracking disease spread among this population. The study was published today in JAMA Network Open and found the incidence of the disease lower than among the general population.
A study of California public transportation workers published today in Morbidity and Mortality Weekly Report (MMWR) shows public transportation workers have higher rates of both COVID-19 incidence and mortality compared to other industries.
Nonhospitalized, high-risk, vaccinated COVID-19 patients who received nirmatrelvir-ritonavir (NMV-r, or Paxlovid) saw a 45% drop in their relative risk of emergency department (ED) visits, hospitalization, and death by 30 days, suggests a study published late last week in Clinical Infectious Diseases.
Selective serotonin reuptake inhibitors (SSRIs), the most commonly used class of antidepressants in the United States, don't appear to prevent severe COVID-19 or death among outpatients, according to a study presented this week at the American Heart Association's Scientific Sessions in Chicago.
A study of US patients aged 0 to 20 years hospitalized for COVID-19 or multisystem inflammatory syndrome in children (MIS-C) in 2020 and 2021 shows that 22% had a neurologic condition, including 9% with life-threatening illness.
An observational study published this week in eClinicalMedicine suggests that COVID-19–related acute kidney injury (AKI) is tied to a greater risk of death, and that severe AKI may lead to poor recovery of kidney function.
JAMA Network Open published a new study yesterday showing higher cord blood COVID-19 antibodies in women who were vaccinated compared with those who were infected with COVID-19, suggesting vaccination produces more than 10-fold higher antibody concentrations in unborn babies compared to natural infections.
Repeat SARS-CoV-2 infections confer significant additional risk of adverse multi-organ medical conditions and poor outcomes such as hospitalization, diabetes, kidney disease, mental illness, death, and diseases affecting the lungs, heart, brain, blood, and musculoskeletal systems, suggests a study published yesterday in Nature Medicine.
A study today in BMC Medicine highlights the toll that the COVID-19 pandemic has taken on the diagnosis of tuberculosis (TB) in high-burden countries, particularly in vulnerable populations.
A UK study suggests that Omicron BA.2 is tied to more symptoms and impeded daily activities than BA.1, and Taiwanese researchers describe fatal cerebral edema in 6 kids with BA.2.
The sensitivities of 3 commonly used rapid antigen tests were very low for Omicron in asymptomatic people.
