Coronaviruses are a large family of viruses and are commonly seen in many species of animals – cattle, cats, bats and camels. Animal coronavirus is not known to be spread to people but in case of novel coronavirus or 2019-nCoV has been transmitted to people and spread between people similar to SARS and MERS.
Person to Person spread happens in close contacts (6 feet) through – respiratory droplets by Coughing, sneezing. The droplets travel through air and land in the nose of mouth of dental staff or any surface nearby and can be inhaled into the lungs leading to spread of the disease. It is not clear if touching any surface having infected droplets and later touching your mouth or nose can lead to the spread of the disease.
Which mouth mask or face mask can prevent spread of Coronavirus?
A regular Surgical or medical mask will not prevent the spread of Coronavirus but a specialized mask known as “N95 Respirator” will help in preventing the disease from spreading to the person wearing it.
The N95 Respirator is thicker and seals the mouth and nose properly from any infectious aerosols from spreading to the person. It is not advised for common people to wear this mask at the moment but medical professionals who can come in direct contact are recommended to wear one. One cannot work for prolonged duration while wearing a N95 Respirator.
