Suara.com – The latest findings of British scientists say the latest variant of COVID-19, which is a derivative of the Delta variant, will be increasingly difficult to detect.
The reason is that the Delta subvariant that developed in the UK is less likely to cause symptoms of COVID-19 infection.
The REACT-1 study by Imperial College London revealed that overall cases have dropped from their peak in October.
The study found that the subvariant known as AY42 appeared in nearly 12 percent of the samples sequenced, but only a third had “classic” COVID symptoms.

Meanwhile, the AY4 subvariant, which now dominates, was found in almost half of the samples.
AY42 is thought to be slightly more contagious, but has not been shown to cause any more severe disease.
Researchers say that people without symptoms (OTG) may be less self-isolating, but people with fewer symptoms may also be more likely to spread the virus through coughing, and may not experience severe illness.
“It seems to be more contagious,” epidemiologist Paul Elliott told the media crew. “Seems minimal symptoms, be a good thing.”
Imperial previously released preliminary study results showing the prevalence of COVID-19 peaked in October and most infections were in children.
The comprehensive results from the last round of studies on Oct. 19 to Nov. 5 confirmed that the infection rate fell from its peak, in line with the school semester holidays at the end of October.
