Exposure To Air Pollution During Pregnancy Enhances Risk Of Respiratory Infections: Study
[ad_1]
Exposure to ultrafine particles during pregnancy enhances the risk of respiratory viral infection, shows a study. During pregnancy, women are more susceptible to severe respiratory infections from multiple viruses, including influenza A virus (IAV), respiratory syncytial virus (RSV), and severe acute respiratory syndrome coronavirus (SARS-CoV-2).
In addition, pregnant women are disproportionately affected by influenza, resulting in a more than 10-fold increase in hospitalisation risk. "We know that air pollution affects the pulmonary immune system, making individuals more susceptible to viral infections," said Dr Natalie Johnson, associate professor at the Texas A&M University School of Public Health. In the study, published in the journal Particle and Fibre Toxicology, the team pointed out that there are several physiological characteristics that explain maternal susceptibility to viral infection.
