By Alaska Physicians and Health Care Workers

Dear Governor Dunleavy,

Thank you for taking precautionary measures regarding COVID-19. The Alaskan physicians and healthcare workers who sign this letter encourage you to mandate the use of masks by customers and employees in businesses open to the public where 6-foot distancing is unrealistic. Recent medical studies and real-world evidence support the use of masks to prevent the spread of the virus.

We are concerned about the recent and rapid increase in COVID-19 case counts in Alaska

(1). We want a healthy and robust economy in Alaska, and a healthy economy needs healthy consumers and workers. More consumers will feel safe patronizing businesses when they know the risk of infection is reduced. In the absence of mandated masking, many Alaskans will continue to shelter in place rather than risk infection. We also want to avoid another lock-down, which would further harm the economy.

There is now robust scientific evidence that masks play an important role in preventing the spread of the virus. A systematic review published June 1st, 2020 in the Lancet looked at 172 studies and found the most effective ways to decrease transmission of the coronavirus include social distancing and universal mask wearing

(2). This is a very inclusive study with the highest quality methodology, and was published in one of the most respected medical journals. We can be confident in the results.

We also have real-time examples of countries that adopted mask wearing and as a result decreased viral infections. In the Czech Republic, masks were mandated in early March for anyone outside their homes. Within two weeks they had an 80% decrease in transmission of the virus

(3). Austria had a similar phenomenon with a 90% decrease in infections two weeks after adopting mask mandates

(4). Widespread mask use is so effective because viral transmission often occurs through respiratory droplets (coughs, sneezes, exhales)

(5). If people infected with the virus wear masks, then these respiratory droplets are trapped in the mask material. This is especially important in the case of asymptomatic carriers. In fact, up to half of the people who spread the virus are infected but don’t know it yet

(6). The takeaway is this: a sick person wearing a mask will spread fewer viral particles. A healthy person wearing a mask will have some protection from sick people around them. The combination of both people wearing masks provides the greatest amount of protection.

Masks are a very low-risk intervention. Masks are safe for the vast majority of people. They are not recommended for certain groups, such as children under two years old, or some people with serious underlying lung conditions under the advice of their clinician

(7). There is no solid evidence for carbon dioxide build-up or mental status changes from long-term cloth mask use in the general public. Many people, like healthcare workers, use masks on a daily basis for years.

Moreover, masks are available. Initially the public was told to not wear masks in order to conserve them for medical use due to shortages. Now there are non-medical grade masks available for the public. The use of masks is recommended by the CDC, the World Health Organization, and by our own State

(8,9,10). Unfortunately, this recommendation appears insufficient to effect the behavioral change needed to protect Alaskans, limit viral spread, and successfully launch our economy. In the United States, as of June 5th, the majority of States and the District of Columbia have face mask requirements

(11). As we’ve seen, if universal masking in businesses is not mandated, it becomes difficult for individual businesses to ask customers to wear them. This is especially concerning in light of the recent rise in case counts this past week. At the beginning of the pandemic in March, cases were clustered in just a few communities. Now we are seeing cases widespread throughout Alaska. Without a mandate for mask wearing, this trend may accelerate.

In addition to supporting our economy, we need to do everything we can to continue to reduce viral transmission so we don’t overwhelm Alaska medical systems, which is still a possibility. We thank you for the early lock-down order for Alaska. Because of this, we flattened the curve. We now need to take the next steps to bridge our communities to a vaccine or better treatment options. This requires a new way of living, and we recognize masks are part of this new reality. We strongly urge you to enact the appropriate Health Mandate requiring universal mask wearing in businesses.
