How canceled events and self-quarantines save lives, in one chart
The main uncertainty in the coronavirus outbreak in the United States now is how big it will get, and how fast. The Centers for Disease Control and Prevention's Nancy Messonnier told reporters on March 9, "many people in the US will at some point, either this year or next, get exposed to this virus."

What we know

The virus that is causing the current outbreak is a respiratory one and spreads through droplet infection.

  • There have been no known cases of the virus spreading through "smear" inf...

Contaminated surfaces

  • The virus can be detected in aerosols (airborne droplets smaller than five micrometers) for up to three hours.
  • On copper, for up to four hours.
  • On cardboard, for up to 24 hours.
  • On stainless steel or plastic, for up to three days.

The virus particles on any surface decrease rapidly at the start, then slowly approaches zero over time.

Touching or eating contaminated food

If a food worker coughs over your food while preparing it, although really gross, your risk of contracting the disease that way is minimal.

According to a 2018 overview of respiratory viruses, the virus reproduces along the respiratory tract. It is a different pathway than the digestive tract food follows when you swallow it.

Even if you handle contaminated food and then deposit the virus along your respiratory tract, it's highly unlikely to get sick this way.

Virus-free transit

Better design could help reduce crowds where viruses can easily spread.
At airports, security screening could be done differently so passengers are not forced to wait in crowded lines. It can reduce congestion and person-to-person contact.

Buildings

Air quality should happen in the public transportation system as well as inside buildings since we spend most of our time indoors.

  • Air can be made much cleaner with UV-C light, for example, that can eliminate viruses in air treatment systems.
  • Bringing fresh air into the buildings is important, as is improving ventilation outside in dense neighborhoods.
  • Future technology may include sensors that can detect viruses on surfaces in real-time that could trigger air cleaning.
  • Some buildings could also deploy temperature screening to identify people who might be ill.

Safety of homemade devices

So far, the evidence is insufficient and mixed; there are a few ideas that show promise,  but there is also some concern that improvised measures could make things worse.
The last thing you want is for healthcare workers to have a false sense of protection and perform a risky procedure on a patient.

Making masks

The medical opinion on homemade masks is mixed. None of the everyday materials you could use to make masks work as well as a commercial surgical mask, but the homemade versions do prevent some microbes from getting through, suggesting these substitute masks are better than nothing at all: they could theoretically slow the spread of disease by helping keep the virus from escaping people’s noses and mouths.
