An Important Note on the Need to Wear Masks When Out and About

Dragon Herbs highly recommends that everyone wears a mask when out and about. This protects you and the general public. Please do not buy medical masks so we do not deplete critical supplies for our medical workers.

"The tests were done at the National Institutes of Health’s Rocky Mountain Lab in Hamilton, Montana, by scientists from the NIH, Princeton University and the University of California, Los Angeles, with funding from the U.S. government and the National Science Foundation."

“When researchers conducted systematic review of a variety of interventions used during the SARS outbreak in 2003, they found that washing hands more than 10 times daily was 55 percent effective in stopping virus transmission, while wearing a mask was actually more effective — at about 68 percent. Wearing gloves offered about the same amount of protection as frequent hand-washing, and combining all measures — hand-washing, masks, gloves and a protective gown — increased the intervention effectiveness to 91 percent.”

“Classified data from the Chinese government that was reported in the South China Morning Post indicated that up to a third of all people who tested positive for the coronavirus could have been silent carriers.”

“Dr. Neil Fishman, the chief medical officer of the Hospital of the University of Pennsylvania… “If everyone in the community wears a mask, it could decrease transmission,” Dr. Fisher said.”

It is worth noting that the aerosol transmission of coronavirus is possible when someone is exposed to high concentrations of aerosol in a relatively closed environment for a long time, according to the Covid-19 Prevention and Control Plan (5th Edition) issued by the National Health Commission (NHC) of China.

The difference between aerosols and droplets is that droplets’ diameters are greater than 5 microns (1 millionth of a meter) and cannot stay suspended in the air while aerosols are airborne with diameters smaller than 5 microns.

NHC is the lead agency in mainland China coordinating the national efforts to combat the coronavirus outbreak. The aerosol transmission (airborne) was added to the 5th Edition of their Covid-19 Prevention and Control Plan published on 2/19/2020. It was listed in their 4th Edition as “pending verification” but was since officially added as a possible transmission route, in addition to respiratory droplets and contact.

Dragon Herbs is making available a small quantity of reusable face masks and replaceable filters. They are not approved for medical use in formal medical settings, but are still highly effective for general use by the public, far superior to conventional disposable face masks. These PM 2.5 filters are shown in lab tests to filter out particulate matters that are 0.1 micron in diameter or larger by at least 95%, meeting or exceeding the US NIOSH N95 filtration efficiency standard.
