Exposure to small- or fine-particle air pollution may predispose COVID-19 survivors to a longer duration of persistent symptoms by increasing the severity of the infection, among other contributing factors, finds a study led by the Barcelona Institute for Global Health (ISGlobal).
A study of sex-based differences in the risk of COVID-19 pneumonia finds that men were more likely to develop the complication than women (12.0% vs 7.0%) during the declared pandemic period and the early months of the endemic phase of the disease in Mexico.
A new meta-analysis of studies involving more than 14 million people published in the Journal of Infection shows that COVID-19 vaccination is associated with a lower risk of developing long COVID, with two doses reducing the odds by 24% and one dose reducing the odds by 15%.
Reduced gas exchange in the lungs -- oxygen coming in, carbon dioxide going out -- appears to be associated with brain fog in long COVID, researchers will report in Chicago at next week's annual meeting of the Radiological Society of North America.
