The British coronavirus variant is still the dominant variant in Bulgaria. The Delta variant is still picking up speed. At the moment the situation in the country is calm, but in a month and a half it will be Delta variant is expected to be the dominant one, Prof. Iva Hristova, director of the National Center for Infectious and Parasitic Diseases, told the BNT breakfast program “The Day Begins” on July 19.
She explained that a recent study found that viral loads in the upper respiratory tract were 1,000 times higher when infected with the Delta variant. And that leads to other consequences.
“People who are infected with the virus transmit it earlier, before they even realize they are sick Delta variant is passed on to others 50-60% more easily than the alpha variant, which in turn is passed on 50-60% more easily than the original variety. If you compare them, it turns out that the Delta variant is two and a half times easier to transmit, said the director of the National Center for Infectious and Parasitic Diseases.
Prof. Hristova reminded that the vaccinated and recovered should be calm, because even if there is a recurring disease, it is very rare and with mild symptoms.
“Each subsequent variant that is becoming dominant in our country affects younger age groups. This is partly a fact that more people from the older age group are being vaccinated, and because people from the older age groups are taking protective measures more seriously, it’s down to individual choice and behavior, “she added.
According to her, the symptoms have changed somewhat. In the original version, the focus was on the loss of the sense of smell and taste, while this is no longer so typical with the change in variant.
“Some non-specific inflammation of the nose and throat comes to the fore with fever, but it progresses downward quite quickly and affects the lower airways and the development of interstitial pneumonia,” explains Prof. Hristova.
She added that Bulgaria has enough vaccines of various types.
