There are several types of SARS-CoV-2 that cause corona infection worldwide. One of these is B.1.617, which was discovered in India earlier this year. The World Health Organization (WHO) has named this type of virus as delta and states that it is more contagious than other variant and has declared it a “variant of concern- VOC”.
Coronaviruses that spread around the world are classified into three variant based on their severity. In the last few days, the WHO has classified the delta type as the second standard VOC. Consequently, the US Centers for Disease Control and Prevention is currently classifying Delta as VOC. It is noteworthy that the delta type was previously classified as First Variant (Variant of Interest) by the CDC.
The World Health Organization’s VOC classification includes the “alpha” found in the UK with Delta, the “beta” found in South Africa, and the “gamma” found in Brazil.
If a coronavirus is classified as VOC, according to the WHO, that means that the mutation potential of the infection may be very high and the severity of the transmitted disease may be high.
According to the latest data released by the UK Department of Public Health, 96% of all new cases of gonorrhoea currently occurring in the UK are caused by delta, and the second most common cause of corona infection there is due to the delta variant rather than the alpha variant that originates there. Furthermore, the effectiveness of the vaccine against the delta variant, the percentage of second-time infected victims, and the lifespan of the infection are being studied.
The US CDC claims that the delta variant is spreading there 50% faster than the alpha. The delta variant increased the corona vulnerability to 10.3% on June 13 from about 5% last May. It is also noted that this type of delta variant is highly contagious and reduces the effectiveness of some antibody therapies.
The Delta variant, which was first identified in India and has had a major impact in some countries, including India and the United Kingdom, has now spread to more than 80 countries and continues to spread around the world with constant mutation, the WHO said.
Meanwhile, the WHO is monitoring the latest reports of the “Delta Plus” variant. Commenting on this, the WHO’s Covid-19 technology head said, “In some delta variant, we have seen a lesser mutation or an elimination instead of a more mutation. So we are looking at all the activities related to this. ”
The Maharashtra State Health Department has warned that the Delta Plus could lead to a third corona wave in India. VK Paul said.
