PM2.5 particles are tiny enough to enter the bloodstream and lodge in the lungs, where they contribute to respiratory problems such as asthma. They also can prompt heart attacks and strokes. And they have been linked to diabetes, obesity and dementia and may exacerbate COVID.

Inside long COVID’s war on the body: Researchers are trying to find out whether the virus has the potential to cause cancer
Long COVID is no stranger to either patients or those immersed in studies of its effects. In the U.S., one in 7 adults–about 14% of the adult population–has experienced symptoms that lasted three months or longer after first contracting the virus. The worldwide estimate for long COVID is 65 million people.
What is less clear–because it’s still so early in the process–is the impact of some of SARS-CoV-2’s most dangerous characteristics on those hit by long COVID. But some researchers are warily watching for the worst: a potential connection to cancer.

Substantial decrease noted in severe respiratory illness during first 2 years of pandemic
Compared to the 3 years prior to the pandemic, children with medically complex conditions and otherwise healthy children saw decreases in severe non-COVID respiratory illnesses in 2020 and 2021, the authors of a study yesterday note in JAMA Network Open.
The cross-sectional study, based on 139,078 respiratory hospitalizations in Canada, shows that the mitigation efforts used during the first several months of COVID-19 likely prevented serious outcomes from respiratory illness complications, including hospitalizations, intensive care unit (ICU) admissions, and death.
