Doctors have been noting new symptoms of coronavirus during the 4^th wave, the Military Medical Academy has announced.

One of the principal symptoms is running a very high temperature over a long period of time, which may reach 40 degrees. Other frequent symptoms include cough, connected with shortness of breath, and the symptoms that are familiar from the British variant. Patients are usually hospitalized on the 6^th or 7^th day after a positive test result. With people who are vaccinated the disease is by far less severe with no respiratory distress.

At the moment the entire country is in the “yellow” zone, with not a single “green” region. Five regions are now in the “red zone” – Burgas, Veliko Turnovo, Turgovishte, Ruse and Plovdiv.
