Adverse Reactions:

Varicella (also known as chickenpox) is a viral illness caused by the varicella-zoster virus.

Occasionally, there may be slight redness or swelling around the injection site or slight dizziness, but these will gradually subside in a few days. If fever or discomforts persist, or abnormal breathing is observed, please consult a doctor immediately.

Chickenpox (varicella) is an acute infectious disease caused by the varicella-zoster virus. It predominantly affects children under 12 years of age. Although almost all persons develop lifelong immunity after a chickenpox infection, the virus may remain latent in the body and recur many years later as herpes zoster (shingles).

Symptoms:

• The patient usually presents with a fever and itchy skin rashes.
• Rashes develop in crops over a period of 5 days on the body, then spread to the face, arms, and legs.
• The rashes first appear as flat spots and later as vesicles. The vesicles continue for 3 – 4 days, then dry up and form scabs.
• The patient usually recovers in about 2 – 4 weeks.
• Persons who have received chickenpox vaccination may still develop chickenpox (known as ‘breakthrough disease’). The clinical presentation is usually mild or atypical. There may be fewer skin lesions and the skin rash is usually maculopapular with few or no vesicles. Compared with non-vaccinated persons, the duration of illness is usually shorter.

Transmission:  It can be spread through droplets or air; can also spread through direct or indirect contact with the discharges from vesicles and mucous membranes of persons with chickenpox or herpes zoster.

Incubation period: 10 – 21 days, usually 14 – 16 days

Infectious period: Usually 1 – 2 days before the rash appears and until all vesicles have dried up. It is extremely contagious, especially in the early stage of rash eruption.

Effects: Chickenpox is generally a mild disease and is usually self-limiting. However, a secondary bacterial infection of the wound may occur. Those with weakened immunity or who are pregnant are most likely to suffer from severe complications such as pneumonia and encephalitis. Newborn babies who develop chickenpox can result in severe illness and even death. Infection in early pregnancy may be associated with congenital malformation of the fetus.
