If you’re hoping to go back to normal, it’s not going to happen. The normal of November 2019, before SARS-CoV-2 got a foothold in the human population, will not return. There will be a time when COVID-19 is no longer one of the top causes of death in the United States and a primary topic of concern around the world. But we can’t know when that will be. I’m guessing it’s at least two years away.

Because of negligence by leaders, particularly President Donald Trump, the virus is everywhere. It will take serious effort to bring it under control. The United States has handled the pandemic almost uniquely badly, but even countries that have minimized cases continue to be affected as well. Vigilance must be constant to keep the virus from returning with travelers. Where there are outbreaks, they will have to be tamped down with isolation, testing, and tracing.

After the long, hard slog to where virus cases and deaths are few, repercussions will continue. Some people continue to have symptoms for months. Because we have only seven months’ experience with the virus, we don’t know how many people will suffer virus-related disabilities, how long they will last or if they will flare up again later.

The Journal of the American Medical Association has a short article saying that the evidence is strong for wearing masks in public.

There is good evidence that masks help both in keeping viruses from being spread by the wearer and also in preventing the wearer from breathing viruses in. Further, wearing a mask does little harm, which is greatly outweighed by the benefit of reducing transmission.

Some selections:

After emerging data documented transmission of SARS-CoV-2 from persons without symptoms, the recommendation was expanded to the general community, with an emphasis on cloth face coverings that could be made more widely available in the community than surgical masks and to preserve personal protective equipment such as N95 respirators to the highest-risk exposures in health care settings. Now, there is ample evidence that persons without symptoms spread infection and may be the critical driver needed to maintain epidemic momentum.

…recent research of household textiles’ performance when used as source control suggests cloth face coverings may be able to do so with acceptable efficiency and breathability.

Like herd immunity with vaccines, the more individuals wear cloth face coverings in public places where they may be close together, the more the entire community is protected. Community-level protection afforded by use of cloth face coverings can reduce the number of new infections and facilitate cautious easing of more societally disruptive community interventions such as stay-at-home orders and business closings.

At this critical juncture when COVID-19 is resurging, broad adoption of cloth face coverings is a civic duty, a small sacrifice reliant on a highly effective low-tech solution that can help turn the tide favorably in national and global efforts against COVID-19.
