How to Prevent or Limit Covid Third Wave: Johns Hopkins Epidemiologist Brian Wahl Explains

A leading epidemiologist from the Johns Hopkins Bloomberg School of Public Health has identified simple but critical steps each of us can take to prevent or, at least, limit a third wave, by first identifying four factors that will increase the R number and thus create a wave. The R number is the number of people an infected person will, in turn, infect. So if the R number is 1.5 it means a 100 people will infect a 150 more. The four factors are summarized by the acronym DOTS where S stands for “The proportion of the population susceptible to infection”, O stands for “The number of opportunities for transmission i.e. super-spreading events where many are infected by a small number of individuals”, T stands for “The probability of transmission” and D stands for “the duration of infectiousness”. In a 25-minute interview to Karan Thapar for The Wire, Dr. Brian Wahl, who is also a member of the Johns Hopkins India Institute Covid-19 Response Task Force, said any of the four factors that make up DOTS can on its own either prevent or limit another wave.
