As the COVID-19 virus mutates and creates new strains of the disease, one is becoming increasingly prevalent in the U.S.—B.1.1.7, known colloquially as the U.K. variant. As of Feb. 9, the Centers for Disease Control and Prevention (CDC) estimates there to be 932 cases of the new strain present in the U.S., spread across 34 different states. But a new study out of the Scripps Research Institute in La Jolla, California, found that the number of cases of the U.K. variant are doubling every 10 days, so it’s definitely something to be on the lookout for. There is a lot of overlap between the symptoms of the existing dominant strain and the new one from the U.K., but a new major review of cases out of Imperial College London is suggesting that one COVID symptom is increasingly likely to show up with the new U.K. variant.

The researchers who conducted the Imperial College London-led REACT study compared two sets of patient data and each COVID symptom that was associated with their case. The first set was from Nov. to Dec. 2020, when it was estimated that just 16 percent of infections were related to the new variant. The second was made up of data from January, by which point 86 percent of infections were linked to B.1.1.7. While most symptoms were similar, there does appear to be one tell-tale sign you’ve contracted the U.K. strain.

While a cough has always been a sign of COVID, it’s become increasingly common with the U.K. variant than loss of smell, which has long been the tell-tale sign of COVID. That symptom, it turns out, has become less common with the U.K. strain, the Imperial College London-led REACT study found. The other discrepancy between symptoms was a persistent cough. Though previously common, the study shows that at the end of 2020, 8.5 percent of patients reported this symptom. In January, that jumped to 11.4 percent, with the researchers noting “increased risk for new persistent cough may be due to variant B.1.1.7.”

“The proportion of people testing positive with a new persistent cough appeared to be increased, in keeping with findings from the ONS,” the researchers wrote, referring to a January study from the U.K.’s Office for National Statistics, which analyzed the symptoms of 6,000 COVID patients in England who tested positive for the virus between mid-November and mid-January. According to their findings, a cough was reported among 35 percent of COVID patients with the U.K. strain, compared to 28 percent of patients with the previous strain.

However, certain additional symptoms were also more common with the U.K. variant, the Imperial College London researchers found. Read on to find out what those are.
