Chickenpox
What it is
Chickenpox, also known as varicella, is a highly contagious viral illness. Red spots or bumps appear on the skin, followed by fluid-filled blisters that eventually form scabs. The skin may be very itchy.
What you can do at home
What to do
- Take acetaminophen (Tylenol). When in doubt, ask a pharmacist for advice.
Caring for the spots
- Take a 10-minute lukewarm bath once a day, as needed.
- Use a mild, unscented soap and rinse thoroughly.
- Pat the skin dry. Do not rub.
- Do not remove firmly attached scabs. Remove only loose scabs that catch onto clothing.
- Moisturize the skin after a bath or shower, for example with a lanolin-based cream, petroleum jelly, or mineral oil, unless this makes the rash worse.
Important: Never leave a child unattended in the bath.
Pain when urinating
- Urinate in the bath or a sitz bath, or while warm water runs over the painful area.
Itchy skin
- Wear loose, soft clothing.
- If the skin is not dry, add baking soda to the bathwater: 50 to 60 mL for children under 2 years of age, or 250 to 500 mL for adults and children aged 2 years and older.
- Apply cold, wet compresses to the skin for 30 to 90 minutes every 2 to 4 hours, as needed.
- Do not scratch the spots.
- For children under 2 years of age: Use mittens as needed to prevent scratching.
Spots on the eyelids
- Clean the eyes with water that has been boiled for 1 minute and has fully cooled.
- Apply wet compresses to the eyelids.
- Gently remove loose scabs.
- Use a separate washcloth for each eye and wash used washcloths.
Spots in the mouth
- Rinse the mouth with cold water, as needed.
- Drink cold fluids.
- Avoid acidic, spicy, salty, hard, or very hot foods.
- Brush teeth with a very soft toothbrush.
- Avoid mouthwash containing alcohol.
- For young children: Use a cup, spoon, or syringe instead of a bottle because sucking increases mouth pain.
- For older children: Use a straw.
- From age 4: Rinse the mouth with a baking soda solution up to 4 times a day. Mix ½ teaspoon of baking soda with 1 cup (250 mL) of water that has been boiled for 1 minute and has fully cooled. Use 5 mL each time for children aged 4 to 6 years, 5 to 10 mL for children aged 6 to 12 years, and 15 mL from age 12.
- Apply an anesthetic gel in the mouth before eating. Ask a pharmacist for advice.
Important: Anesthetic gel is not recommended for young children. When in doubt, ask a pharmacist for advice.
To prevent spreading the infection
- Wash hands often.
- Do not share items that have been in contact with the sick person’s mouth.
- Stay home during the most contagious period.
- Avoid close contact with other people, especially babies, children, older adults, and people who are immunocompromised.
- Regularly clean and disinfect frequently touched surfaces and objects.
Avoid
- Scratching the skin
- Sun exposure, because heat makes itching worse
- Ibuprofen (Advil) or aspirin
- Swimming until all the blisters have turned into scabs
