Skin reactions after COVID-19 vaccination: Rare, uncommonly recur after second dose
(Massachusetts General Hospital) Skin problems after a first mRNA COVID-19 vaccine dose occurred in 1.9% of surveyed employees from hospital system Mass General Brigham. Among employees who experienced a skin reaction to the first dose, 83% had no recurrence of symptoms following the second dose. (Source: EurekAlert! - Infectious and Emerging Diseases)

Pandemic drives largest decrease in US life expectancy since 1943
(Virginia Commonwealth University) US life expectancy decreased by 1.87 years between 2018 and 2020, according to research publishing June 23 in The BMJ from Virginia Commonwealth University, the University of Colorado Boulder and the Urban Institute. The numbers are worse for people of color. On average, whereas life expectancy among white Americans decreased by 1.36 years in 2020, it decreased by 3.25 years in Black Americans and 3.88 years in Hispanic Americans.

COVID-19 disruptions in sub-Saharan Africa will have substantial health consequences
(Harvard T.H. Chan School of Public Health) The COVID-19 pandemic poses substantial indirect risks to sub-Saharan African countries with fragile health systems and high levels of poverty, malnutrition, and other infectious diseases. New survey data from Burkina Faso, Ethiopia, and Nigeria provides evidence for public policy to mitigate against nutrition, health, social, and economic impacts of COVID-19 as the pandemic continues to spread on the continent.

Long COVID symptoms likely caused by Epstein-Barr virus reactivation
(World Organization) Epstein-Barr virus (EBV) reactivation may be the cause of previously unexplained long COVID symptoms -- such as fatigue, brain fog, and rashes -- that occur in approximately 30% of patients after recovery from initial COVID-19 infection. The first evidence linking EBV reactivation to long COVID, as well as an analysis of long COVID prevalence, is outlined in a new long COVID study published in the journal Pathogens.

NIH scientists describe 'multi-kingdom dialogue' between internal, external microbiota
(NIH/National Institute of Allergy and Infectious Diseases) National Institutes of Health scientists and their collaborators have identified an internal communication network in mammals that may regulate tissue repair and inflammation, providing new insights on how diseases such as obesity and inflammatory skin disorders develop. The new research is published in Cell. (Source: EurekAlert! - Infectious and Emerging Diseases)

NIH begins study of COVID-19 vaccination during pregnancy and postpartum
(NIH/National Institute of Allergy and Infectious Diseases) A new observational study has begun to evaluate the immune responses generated by COVID-19 vaccines administered to pregnant or postpartum people. Researchers will measure the development and durability of antibodies against SARS-CoV-2, the virus that causes COVID-19, in people vaccinated during pregnancy or the first two postpartum months. Researchers also will assess vaccine safety and evaluate the transfer of vaccine-induced antibodies to infants across the placenta and through breast milk.

New class of compounds found to block coronavirus reproduction
(NYU Langone Health / NYU Grossman School of Medicine) A human genetic mechanism hijacked by SARS-CoV-2, the coronavirus behind the COVID-19 pandemic, to help it spread also makes it vulnerable to a new class of drug candidates, a new study finds.

Research provides a roadmap to HIV eradication via stem cell therapy
(University of California - Davis Health) A groundbreaking study found that stem cells reduce the amount of virus causing AIDS, boost the body's antiviral immunity, and restore the gut's lymphoid follicles damaged by HIV. It provided a roadmap for multi-pronged HIV eradication strategies. (Source: EurekAlert! - Infectious and Emerging Diseases)

Had COVID-19? One vaccine dose enough; boosters for all, study says
(American Chemical Society) Two mRNA vaccines against COVID-19 have proven safe and effective in clinical trials, as well as in the millions of people who have been vaccinated so far. But how prior SARS-CoV-2 infection affects vaccine response, and how long that response lasts, are still uncertain. Now, a new study in ACS Nano supports increasing evidence that people who had COVID-19 need only one vaccine dose, and that boosters could be necessary for everyone in the future.

Research may help identify more dangerous strains of the virus that causes COVID-19
(Wiley) Viral mutations during the COVID-19 pandemic could cause the SARS-CoV-2 virus to become more dangerous. A new study published in Genetic Epidemiology has examined the genetic code of SARS-CoV-2 viruses that have infected patients, looking for links between different mutations and patient deaths.

Tree pollen carries SARS-CoV-2 particles farther, facilitates virus spread
(American Institute of Physics) A study on the role of microscopic particles in virus transmission suggests pollen is nothing to sneeze at. In Physics of Fluids, researchers investigate how pollen facilitates the spread of an RNA virus like the COVID-19 virus. The study draws on cutting-edge computational approaches for analyzing fluid dynamics to mimic the pollen movement from a willow tree, a prototypical pollen emitter. Airborne pollen grains contribute to the spread of airborne viruses, especially in crowded environments. (Source: EurekAlert! - Infectious and Emerging Diseases)
