COVID-19 Delta Strain Triggers Different Symptoms

COVID-19 Delta Strain Triggers Different Symptoms

The Delta strain (B.1.617.2 variant), which originated in India back in December, has been taking over the planet, and it is now the dominant variant in many countries, including the U.S. The World Health Organization (WHO) has labelled the Delta strain a ‘variant of concern’. This means that the strain is more dangerous than other mutations suffered by the original SARS-CoV-2 virus, identified in Wuhan in 2019. 

The Delta variant conquered the U.S

If at the beginning of the summer, in June, this strain accounted for about 30 % of coronavirus infections in the U.S, it has quickly evolved in becoming the dominant one, with about 83% of new coronavirus infections and the number continues to surge, according to new statistics. Researchers expect the number of infections to keep on growing and advice the U.S population to get their Covid vaccines. The available Covid-19 vaccines in the U.S are for 12 years old, and more people can choose between Pfizer BioNTech, Moderna or Johnson & Johnson. 

The Delta strain triggers different symptoms

Although it is a mutation of the original SARS-CoV-2 virus, the Delta strain has a higher infection rate, and it is much more aggressive. In addition, health officials have discovered that it triggers different symptoms compared to the original virus and other variants. If the typical symptoms of Covid-19 infection were loss of smell and taste and cough, it seems that those infected with the Delta strain experience headaches, sore throat, fever and nose congestion. It is unclear so far why this strain triggers symptoms similar to a traditional cold. Still, research shows that compared to the Alpha variant, which originated in the U.K, the Delta strain is 50% more contagious. This is not good news considering that past research showed that the Alpha variant was 50 % more contagious than the original COVID-19 virus.
