Update news medical mask
Wakamono, a HCM City company that specialises in producing nano biotech materials, has invented a medical mask that is capable of killing more than 99 per cent of both gram-negative and -positive bacteria, and enveloped and non-enveloped virus.
The city's leader requires the health sector to be well-prepared for the worse situation.
