The role of absolute humidity on transmission rates of the COVID-19 outbreak

Category:

Topic:

  • Researchers evaluated absolute humidity and transmission of COVID-19. They found that high humidity will not necessarily limit the survival and transmission of the virus. 
  • Sustained and exponential disease transmission can occur across a range of humidity conditions. Thus, changes in weather will likely not lead to reduced case counts without extensive public health interventions.
