2.1.2.1 Anemia
It follows a chronic course, with anemia often being the initial and primary manifestation. Common symptoms include pallor, fatigue, dizziness, palpitations, and shortness of breath after activity. Symptoms may improve after blood transfusion, but the effect does not last long.
2.1.2.2 Infection
High fever is less common than in the acute type; respiratory tract infections are more frequent, with fewer severe complications, making them relatively easier to control.
