Health Implications of Bioaerosol Exposure

Certain groups of people are particularly susceptible to adverse health effects following exposure to bioaerosols. The children are likely to have breathing issues, in fact, allergies (including infections) as the immune systems of such children are not yet adequately developed to react to bioaerosols. The elderly are also not spared, as they have decreased immune and respiratory reserve capacities, which can lead to chronic respiratory illness in areas where long-term exposure aggravates the impact. Immunocompromised patients, like patients with cancer and persons with chronic diseases like HIV/AIDS, are at a higher risk of infections and complications due to their weak immune system. More than at any other time, the COVID-19 pandemic has underscored the role of bioaerosols in the spread of airborne diseases. The global pandemic of SARS-CoV-2 has especially highlighted the importance of a universal public health approach to establishing effective indoor air management practices to protect against the spread of airborne viruses. The COVID-19 crisis has dramatically increased the need for research and innovation in air filtration and ventilation systems and disinfection technologies that help reduce the spread of infectious bioaerosols in healthcare facilities, educational institutions, and workplaces. The need to manage indoor air quality is now of the utmost importance. It involves routine ventilation, high-quality air filtration systems, humidity management, and disinfection solutions to significantly reduce levels of harmful bioaerosols in indoor environments.
