- A new study indicates that the people most likely to contract the new coronavirus are young, middle-aged adults.
- The study found that people between the ages of 20 and 49 were responsible for more than 70% of COVID-19 transmission in the US. But most people who experience severe and life-threatening COVID-19 are over 50 years old.
- Additional mitigation measures may be needed to reduce the transmission of outbreaks, including vaccination of younger age groups that are more likely to spread the disease.
The number of daily coronavirus cases has fallen in recent weeks in the United States and other countries that experienced massive spikes in late 2020, just as vaccination campaigns increase. But the virus is still spreading at alarming rates. America’s COVID-19 infection curve could finally point downward, but the country still records more than 120,000 infections a day. In addition, three new coronavirus strains are spreading rapidly, including mutations in the United Kingdom, South Africa, and Brazil. The South African version may elude the action of neutralizing antibodies to the previous COVID-19 and favor reinfection, which means that the mutation may also reduce the effectiveness of the vaccine.
These mutations could always feed new waves if health measures are not respected and if vaccination campaigns cannot be expanded. The latest discovery leads home to the same point, describing the steps that should be taken with the age group that is primarily responsible for the spread of COVID-19.

The CDC has just explained how most people are likely to catch COVID-19. They will contract the disease when they are less than six feet away from someone who is infected. When that person coughs, sneezes, or just talks and breathes, drops and aerosols can be released into the air and infect others.
Researchers in the Department of Mathematics at Imperial College London have now identified the group of people most likely to disperse these virus-laden particles.
According to the new study published in Science, people between the ages of 20 and 49 are responsible for at least 70% of coronavirus transmission in the United States. The scientists found that school-age students up to the age of 19 only contributed 15% of COVID-19 transmission. The study also indicates that the most affected age group were people over the age of 50, who recorded the highest number of deaths in late summer and fall 2020.
“This addresses this underlying false narrative … that if you protect the most vulnerable, you can let the virus go,” Dr. John Brownstein ABCNews. “If you let it run in younger age groups, it will still affect the elderly and vulnerable groups.” Brownstein is an epidemiologist at Boston Children’s Hospital and did not participate in the investigation.
The researchers relied on mathematical and mobility data to model COVID-19 transmission and found that the movement of young and middle-aged adults was the main driver of infections.
“Some age groups, like young adults, dropped their guard,” Brownstein said. “[The report] it puts more responsibility on those younger age groups who were trying to live a normal life and were a little tired of COVID ”.
The health expert also addressed school reopening, saying the report indicates that children are not the main driver of infections.
This new study also provides suggestions on how to mitigate other outbreaks. “In places where new highly transmissible SARS-CoV-2 lineages have not yet been established, additional interventions among adults aged 20 to 49, such as mass vaccination with vaccines that block transmission, could control resurrected COVID-19 epidemics and prevent death, ”the researchers wrote.
Vaccines against COVID-19 are scarce at the moment, so only a few categories of people can qualify them in most places. Young and middle-aged adults should still wait to be eligible unless governments make changes to vaccination protocols. As for the “additional interventions” that can reduce the risk of transmission, they remain the same, regardless of mutations. Facial masks, social distancing, frequent hand washing, proper ventilation of indoor spaces, and avoiding indoor crowding have been shown to reduce the risk of spreading COVID-19.
