Microbial entities (such bacteria, fungi, archaea and viruses) within outdoor aerosols have been scarcely studied compared with indoor aerosols and nonbiological components, and only during the last few decades have their studies increased.

Background During the COVID-19 pandemic, aerosol spread of SARS-CoV-2 has been a major problem in healthcare facilities, resulting in increased use of supplementary HEPA filtration to mitigate transmission. We report here a natural experiment that occurred when an air filtration unit (AFU) on an inpatient ward for older people was accidentally switched off.

Background: Automobile exhaust contains precursors to ozone and fine particulate matter (PM ≤ 2.5 µm in aerodynamic diameter; PM2.5), posing health risks. Dependency on car commuting also reduces physical fitness opportunities.

The purpose of this study was to determine the microbiological air quality (psychrotrophic bacteria and airborne fungi) and distribution of fungi in different types of ready-to-eat (RTE) food-storage refrigerators (n=48) at selected retail stores in the city of Edirne,

This study tested the hypothesis of airborne transmission of Salmonella Agona (Trial I) and Salmonella Typhimurium (Trial II) in weaned pigs.

Background. The high transmissibility and widespread environmental contamination by Clostridium difficile suggests the possibility of airborne dissemination of spores. We measured airborne and environmental C. difficile adjacent to patients with symptomatic C. difficile infection (CDI).

As COVID-19 continues to spread, infection risk on public transport is concerning. Air exchange rates (ACH) and advection–diffusion of CO2 and particles were determined in a route bus to evaluate the infection risk. ACH increased with bus speed whether windows were open or closed, and ACH were greater when more windows were open.

Today the US Food and Drug Administration (FDA) authorized a second booster shot for Americans over 50 and for those 12 years and older who are immunocompromised.

Avian flu outbreaks expanded in six already-affected states, especially in the Midwest, according to the latest announcements from federal and state health officials. Also, Canada reported two outbreaks on Ontario farms, the first since the virus struck flocks in eastern provinces earlier this year.

Antibiotic resistance in Salmonella and Campylobacter bacteria is still high, says a report released today by the European Centre for Disease Prevention and Control (ECDC) and the European Food Safety Authority (EFSA).
