Singapore has confirmed 4th case of coronavirus. Three of the patients had stayed at hotels in Sentosa.
Recently, I noticed many people coughing in the public transport(buses and MRT) and I'm surprised that they did not wear masks. A World Health Organization doctor said that wearing surgical mask works but you need to wear it correctly. The blue colour (waterproof) of the mask should be on the outside and the white colour on the inside as it is made of absorbent material. So if you cough, it absorbs it. Remember to wear mask if you cough or sneeze.
