Research has shown that the delta variant is 60% more contagious than the alpha variant, and people with the previous coronavirus variants infected two others. People with delta can infect 5 more people.
The lower the rate of vaccination in the community and geographical location, the stronger the delta strain will be in shaping a larger epidemic and pathogenicity. However, if the vaccination rate is high in a community or geographical area and different groups have been vaccinated, then the delta variant will be able to cross from one low-coverage area to another low-coverage area, and an epidemic will develop. This phenomenon is misleading in areas where vaccination rates are very low.
In communities such as rural areas, suburbs, poor countries where there are no sanitation facilities and vaccines, or vaccination rates are very low, the delta variant will be vulnerable to people in that community. In North America, for example, vaccination rates are high, but in South America, vaccination rates are very slow, while people in the South American community suffer from diseases such as diabetes and obesity.
“The delta variant is a special and very dangerous threat to poor countries that do not have access to vaccines, Such as Africa.” said a senior adviser to the World Health Organization.
