A Hongkonger’s Voice - Universal Masking
A youtube video posted on 12 May explains the importance of wearing masks to combat the COVID-19 epidemic. Despite having one of the highest population densities in the world, Hong Kong has had relatively few infectious cases because people learned the importance of wearing masks during SARS in 2003.
Professor Yuen Kwok-yung as a key researcher of the SARS coronavirus, stated that wearing masks would prevent the spread of disease, whether symptoms were present or not. "Those who are susceptible ... would protect themselves from getting infected." He stressed its importance in urban areas where social distancing can be challenging. "Even in less crowded places ... a surgical mask can help and remember that wearing a mask itself is a symbol of civility in Hong Kong. When you wear a mask, people think that you are very responsible, very conscientious."
Dr Fan Ning, former president of Medecins Sans Frontieres HK and current chairman of Health in Action said, "When I run out of surgical mask, I would wear cloth mask because it still protects against the ... transmission of diseases."

Dr Kwong examined easily accessible materials that can be used as a filter in his double cloth cotton mask. Before choosing a filter, it is important to know the material's filtration efficiency and PD flow rate. The former specifies effectiveness in filtering out particles; the latter specifies breathability. Dr Kwong says 70% filtration efficiency is sufficient for general use.
Recommendations: Use a new filter every time. Make sure it fills up the mask so the air you breathe passes through the filter. The mask should cover your nose and mouth with the mask fitted snuggly. Wash your hands thoroughly before and after wearing the mask.

A Hongkonger’s Voice on Coronavirus #UniversalMasking
Hong Kong has learned from the 2003 SARS coronavirus that, MASKS HELP. Even cloth masks are proven to be good protection. The HK Mask, created by a Hong Kong chemist Dr. K Kwong, was lab tested on its filtration efficiency at MPPS (0.3 micron particle size)…
