🚨Large study of >500,000 people in #India exposed to the #coronavirus found:

▶️Viral spread is driven by a small % of "superspreaders"
▶️Children & young adults are much more important to viral spread—especially within households—than previously reported

Important findings in the largest #COVID19 contact tracing study to date:

1⃣Children are "key" to the spread of the #coronavirus
2⃣Evidence that much of viral transmission occurs via "superspreaders"

This HUGE study, the largest #coronavirus contact-tracing study to date, was conducted by researchers in #India and the US and tracked the infection pathways and mortality rate of 575,071 individuals exposed to 84,965 people with confirmed #COVID19.

The huge study shows the "extraordinary extent" that #SARSCoV2 hinges on “superspreaders," a small % of infected people who spread the virus:

▶️71% of infected people did NOT infect any contacts
▶️A *mere 8%* of infected people accounted for *60% of new infections*🦠

#COVID19

This large study found:

▶️Chances of a #coronavirus-infected person, regardless of age, spreading it to a close contact were from 2.6% in the community to 9% in the household
▶️Children and young adults—1/3 of #COVID19 cases—were "especially key" to transmitting the virus💥

The overall probability of catching #coronavirus ranged from 4.7% for low-risk contacts up to 10.7% for high-risk contacts (eg, same household).

Across all age groups–including kids and young– people had a greater chance of catching the #coronavirus from someone their own age.🦠
