👉 Infectious mononucleosis, commonly known as "cricket infection," is a viral illness primarily caused by the Epstein-Barr virus (EBV). This highly contagious virus spreads through saliva, making it easily transmitted via kisses, shared utensils, or contaminated surfaces. Symptoms typically appear 4 to 14 days after exposure and include fever, fatigue, sore throat, swollen lymph nodes, and sometimes a distinctive rash or splenomegaly (enlarged spleen). The infection can also lead to more severe complications in certain individuals, such as hemolytic anemia, hemophagocytic syndrome, and neurological issues. While often mild in adults, it can be particularly dangerous for young children and immunocompromised individuals, necessitating close monitoring and sometimes antiviral treatment.
