Doctors have identified the most effective means of protection against coronavirus

A new study by specialists from the UNC School of Medicine and the UNC Gillings School of Global Public Health in the USA showed which methods of protection against COVID-19 are most effective in terms of the specificity of the spread of viral infection.

According to recent data, the virus primarily “settles” in the nasal cavity. So, the ACE2 receptor, which the virus uses to penetrate the cells, is more common on the nasal mucosa and much less on the surface of the cells of the lower respiratory tract (in the lungs). This makes the cells of the mucous membrane of the upper respiratory tract more susceptible to infection.

To protect your lungs from SARS-CoV-2, you must first protect your nose.

– If the nose is the dominant starting point from where the infection can spread to the lungs, then to protect yourself against COVID-19 you really need to wear a mask and use any therapeutic strategies that reduce the likelihood of the virus present in the nose. The latter include, for example, antiviral nasal sprays, ”said Dr. James Moeser, MD, professor.

Earlier, Vladimir Zaitsev, Ph.D. in Medicine, otorhinolaryngologist of the highest category, recommended using oxolin ointment for protection against COVID-19. She needs to lubricate her nose, laying a small amount of an antiviral agent inside the cavity. The ointment should be applied before going outside and updated throughout the day.
