On Friday, May 7, the US Centers for Disease Control and Prevention (CDC) issued a new official recommendation to explain the aerial transmission of coronavirus disease 2019 (COVID-19). The CDC now explains that both SARS-CoV-2 virus infections and infections that cause COVID-19 disease can result from inhaled fine respiratory bioaerosol particles.
The new guidelines are now in perfect agreement with the scientific perspective of a year ago. In contrast to airborne transmission, the CDC’s previous official statement was that the majority of infections occurred through large droplets and close contact with vectors. A new perspective for Marcelo Logsman, who received his PhD in Environmental Sciences and Engineering from the University of Kentucky, Professor of Chemistry on April 7, 2020. The California Institute of Technology degree was published as a preprint attempting to persuade scientists and public health authorities to pay serious attention to the SARS-CoV-2 aerial threat. The second version of the preprint was later released on April 22nd and passed a peer review on the publication of open access journals on December 8th at the International Journal of Health Planning and Management. This study clearly explained the dangers of small bioaerosol particles that can remain in the air over time and penetrate various levels of the respiratory system.
To outline recent changes, the CDC has risks associated with inhalation of the virus, such as deposits on exposed mucous membranes and direct contact with the mucous membranes with dirty hands contaminated with the virus. Claims to be. The impact directly applies to indoor environments such as workplaces, schools and public transport where proper ventilation or air purification systems are lacking. Many follow-up studies published in the previous semester revealed the role of small bioaerosol particles on human health.For example, recent international open access papers Environmental Studies and Public Health Journal Published in January, it refers to a list of recommendations for preventing the transmission of the SARS-CoV-2 virus in the air. The study recommended efforts to control ventilation associated with the spread of the virus in restaurants, cruise ships, nursing homes, schools, kindergartens, offices, shops, and public transport to control pandemics. The use of suitable personal protective equipment, mechanical air filters, UV germicidal irradiation (UVGI), high efficiency particulate air (HEPA) filters, and ion generators was recommended.
Efforts to stop the spread of COVID-19 should focus on preventing airborne transmission
