What has made this Coronavirus so problematic has been its high level of infectiousness. It can live on surfaces for days and in the air for hours. Individuals may have the virus and be spreading it for as much as 5 days before they exhibit symptoms, and may be contagious for up to two weeks.
The COVID-19 virus is spread two ways.
Fomite Spread (on surfaces)
Most people get infected in their own home. A household member contracts the virus in the community and brings it into the house where sustained contact between household members leads to infection. This short video provides an overview of how COVID is spread.
Summaries and distillation of the current research that has been completed and broadly circulated are included in a study done by a PhD at UMass that provided insight in particular to how airborne spread occurs. A formula: Exposure to Virus x Time = Infection. Work by Erin Bromage PhD provides a very insightful look at exactly how the virus spreads and the extent to which you are at risk in a variety of settings. MORE
Personal Protective Equipments (PPEs)
PPEs are a central and critical part of any disease prevention strategy. The shortage of such was a major challenge in the COVID-19 outbreak. The US had failed to refresh its supply of such after the 2009 Swine Flu outbreak or H1N1.
China, which is the major supplier of PPEs, had limited exports upwards of 80% of PPEs. This continues to be a major challenge as demand continues and the expectation of a new wave of cases in the coming months has put a strain on demand.
