After the COVID-19 Delta variant, the Delta plus variant started to spread in Turkey as well as in the world. Anadolu Health Center Infectious Diseases Specialist Assoc. Dr. Elif Hakko said, “2 doses of vaccine also protect against mutations, but two doses of vaccination are not enough for herd immunity yet. We must be careful in the normalization process," he said.
What is the Delta Variant?
The COVID-19 Delta variant was first encountered in India. The World Health Organization warned that the Delta mutation is spreading much faster than the original COVID-19.
What is the delta plus variant?
The Delta Plus variant is a remutation of the Delta variant seen in India in countries outside of India. The Delta Plus variant, first seen in South Africa, has the mutation of the spike protein called K417N, which is seen in the Beta variant.
Why is the delta variant more dangerous?
The delta variant is more dangerous because it infects faster than other mutations. According to studies, the Delta variant predominantly affects young people, as young people are more involved in social life.
What are the symptoms of the delta variant?
The symptoms of classic Covid-19 are predominantly high fever, new and persistent cough, and loss of taste and/or smell. In the delta variant, on the other hand, symptoms of headache, runny nose and sore throat are seen predominantly compared to the classic COVID-19 virus. These symptoms are manifested by a severe cold symptom in young people. However, loss of taste and smell is also observed in the Delta variant.
Who is more at risk?
Those who are not vaccinated, have chronic diseases and people over 65 are at risk.
Can vaccinated individuals also transmit the Delta variant to others?
Vaccinated individuals can also become infected with the Delta variant. Although the disease is milder in those who are vaccinated, they can transmit the variant virus. Being vaccinated protects oneself and does not prevent the disease from carrying and transmitting it. For this reason, even if you are vaccinated, mask, distance and hygiene are essential!
How do vaccines protect against mutations?
According to studies, two doses of Pfizer/BioNTech vaccines provide 79 percent protection against the Delta mutation. You must be vaccinated against COVID-19 and mutations.
When does the epidemic seem like it can be brought under control with vaccines?
After reaching 60 percent in vaccination, we can talk about herd immunity. The faster this time, the better.
Now, there is talk of the “lambda variant” that originated in Peru. Should we be afraid of these variants? Is it true that it's more contagious than the delta variant?
We do not have clear information on this subject. However, the way of protection from the epidemic is always the same: Mask, distance, hygiene...
