varicels

Varicels, commonly known as chickenpox, 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 had the disease or been vaccinated. The illness is characterized by an itchy rash that appears as small, red spots or bumps. These spots typically develop into fluid-filled blisters, which then break open and crust over. The rash usually begins on the face, chest, and back, then spreads to the rest of the body.

Other symptoms of varicels can include fever, headache, fatigue, and loss of appetite, often appearing one to two days before the rash. The incubation period for chickenpox is usually between 10 and 21 days after exposure to the virus. Transmission occurs through direct contact with the fluid from the blisters or through respiratory droplets from an infected person's cough or sneeze.

Most cases of varicels are mild, especially in children, and resolve within one to two weeks. However, complications can arise, particularly in infants, adults, and individuals with weakened immune systems. These complications can include bacterial skin infections, pneumonia, encephalitis (inflammation of the brain), and Reye's syndrome. Vaccination is a highly effective method for preventing varicels and its associated complications. Antiviral medications may be prescribed for individuals at high risk of severe disease.
