Can face mask prevent infection of Corona Virus?




Face masks are reportedly selling out in cities across Asia as concerns over the spread of a deadly new coronavirus grow. China’s National Health Commission has deployed masks to healthcare workers responding to the outbreak, and millions of masks have been sent to residents of Wuhan, according to reports. But will these masks stop people from catching the virus?
Paper face masks are not generally recommended by the NHS for ordinary citizens – with good reason. 
They are ill-fitting and what protection they might initially provide soon expires. Worse, over time they can become moist providing the perfect environment for germs to thrive in. They also become a hazard for others if carelessly discarded.
However, an exception to this would be if you were displaying symptoms such as coughing or sneezing – then a mask may help prevent you spreading the virus to others in busy locations.
In hospitals, healthcare workers treating patients with the virus will wear masks but these are specialist devices and there are strict protocols they must follow to ensure they remain safe and effective.
N95 respirators offer more protection. Such devices are designed to prevent 95 per cent of small particles from entering the nose and mouth area. But they only work if they fit properly, and aren’t suitable for children or people with facial hair.
N95 respirators can also make it more difficult for a person to breathe, so could be dangerous for someone showing symptoms of infection of the new coronavirus, which include coughing and shortness of breath.

Corona viruses  are a large family of viruses that are common in many different species of animals, including camels, cattle, cats, and bats. Rarely, animal coronaviruses can infect people and then spread between people such as with  MERS  and  SARS . Early on, many of the patients in the outbreak of respiratory illness caused by 2019-nCov in Wuhan, China had some link to a large seafood and live animal market, suggesting animal-to-person spread. However, a growing number of patients reportedly have not had exposure to animal markets, indicating person-to-person spread is occurring. L ike other coronaviruses – such as the common cold – the virus is spread via droplets when a person coughs or sneezes. It can also be spread when someone touches a contaminated surface such as a door handle.  H ospitals are also key locations for "super spreading" events - when a single patient infects many people. When patients arrive in hospital with vague respiratory sy
