Chickenpox

The varicella-zoster virus (VZV) causes the very highly contagious viral infection known as chickenpox. It mostly affects youngsters but can also strike adults who have not been vaccinated or been past infected. The virus travels on infected surfaces, through direct touch with blisters, or via respiratory droplets.
Beginning with fever, lethargy, headache, and loss of appetite, symptoms show up 10 to 21 days following exposure. An itchy red rash follows from which fluid-filled blisters finally scab over. Usually beginning on the face, chest, and back, the rash travels the body.
While most instances of chickenpox are minor, in immunocompromised people, bacterial skin infections, pneumonia, encephalitis, or serious disease can develop. Complications are also more likely for babies and expectant mothers.
Although there is no particular cure for chickenpox, supportive treatment consists of water, fever reducers, and antihistamines for itching. Given in two doses during childhood, the varicella vaccination is the best preventive action available.
The virus stays dormant in the body after healing and could reactivate later in life as shingles, or herpes zoster. Early diagnosis and widespread immunisation help stop chickenpox from spreading and lower its consequences.
