Transmission of SARS-CoV-2: implications for infection prevention precautions
We are Globally witnessing many debates on the spread of Corona virus, stay away from the misinformation and associated myths. Please seek, scrutinize, and follow only the trusted sources. It is very important for the effective prevention of oral problems and self-care during this COVID-19 pandemic. Let us take a look at specific needs and considerations for essential oral health services in this context in accordance with WHO operational guidance on maintaining essential health services. Advising the patients through remote consultation or social media plays a vital role. Transmission of SARS-CoV-2, the virus that causes COVID19, can occur through direct, indirect, or close contact with infected people through infected secretions such as saliva and respiratory secretions or through their respiratory droplets, which are > 5-10 μm in diameter. Droplets <5μm in diameter are referred to as droplet nuclei or aerosols. . When AGP cannot be avoided, assistance during procedures (four-handed dentistry), the use of high-speed suction and of a rubber dam, when possible, as well as the use of appropriate PPE – including a fit tested N95 or FFP2 respirator, or higher have to be ensured. Carrying out one cycle of standard cleaning and disinfection according to the standard operating procedures (SOP) of the entire treatment area (environmental surfaces) after every patient in the context of COVID-19 is mandatory. Single visit procedures are to be prioritized to avoid re-call visits. Gain awareness regarding management of health care waste following best practices, reprocessing, routine policies and procedures.COVID-19 is transmitted mainly in three ways in oral health care settings:
- Direct transmission through inhalation of droplets generated through coughing or sneezing;
- Direct transmission via exposure of mucous membrane such as eye, nasal or oral mucosa to infectious droplets; and
- Indirect transmission via contaminated surfaces.
