Vesirokkoa

Vesirokkoa, commonly known as chickenpox in English, is a highly contagious viral infection caused by the varicella-zoster virus. It primarily affects children but can also occur in adults who have not been vaccinated or previously infected. The hallmark symptom of vesirokkoa is an itchy rash that typically begins on the face and torso before spreading to other parts of the body. This rash progresses through several stages, appearing first as red spots, then developing into fluid-filled blisters that eventually crust over and fall off.

Other common symptoms of vesirokkoa include fever, fatigue, headache, and loss of appetite, which usually appear one to two days before the rash. The infection is spread through direct contact with the rash or by inhaling respiratory droplets from an infected person's cough or sneeze. People with vesirokkoa are contagious from one to two days before the rash appears until all the blisters have crusted over.

While generally a mild illness, complications can arise, particularly in infants, pregnant women, and individuals with weakened immune systems. These complications can include pneumonia, encephalitis, and secondary bacterial infections. Vaccination against varicella is highly effective in preventing vesirokkoa and its complications. In most cases, treatment focuses on managing symptoms, such as relieving itching with lotions or medications, and preventing scratching to avoid secondary infections.
