Most of us remember chicken pox as that itchy childhood illness that kept us home from school for a week. Red spots everywhere, calamine lotion dabbed on constantly, and strict instructions not to scratch. For generations, getting chickenpox was almost a rite of passage, something every kid went through eventually.
But here’s what many people don’t realise: chicken pox isn’t always the mild inconvenience we remember. The varicella zoster virus that causes this disease can lead to serious complications, especially in adults, pregnant women, newborns, and people with weakened immune systems. Pneumonia, bacterial skin infections, encephalitis (brain inflammation), and in rare cases, death.
These aren’t exaggerations but documented risks. The varicella vaccine has been available for decades, and it works remarkably well, making Chickenpox preventable. If you’re wondering whether you or your family should get vaccinated, this blog covers everything you need to know.
What Is Chicken Pox?
Chicken pox, also called chechak in some regions, is a highly contagious disease caused by the varicella zoster virus. It spreads through respiratory droplets when an infected person coughs or sneezes and through direct contact with the fluid from chickenpox rash blisters.
Symptoms of chickenpox usually appear 10-21 days after exposure. Early-stage chicken pox begins with fever, fatigue and loss of appetite. Within a day or two, the characteristics of the chicken pox rash develop, starting as small red spots that quickly turn into fluid-filled blisters (chicken pox pimples), then crust over and scab.
The rash typically goes through several chicken pox stages: flat red spots, raised bumps, fluid-filled blisters and finally scabs. New spots continue appearing for 3-5 days, so you’ll often see all at once on different parts of the body.

Why Is Chickenpox a Concern?
For healthy children, chicken pox is usually manageable with proper chicken pox self-care. However, the disease poses serious risks for certain groups:
- Chickenpox in adults tends to be more severe, with higher rates of pneumonia and other chickenpox complications.
- Pregnant women face risks to themselves and their babies, including birth defects and life-threatening neonatal varicella.
- Immunocompromised individuals can develop severe, prolonged illness.
- Newborns whose mothers develop chickenpox around delivery are at high risk.
Important: after recovery, the virus remains dormant and can reactivate years later as shingles, a painful condition affecting older adults.
How Is Chickenpox Transmitted?
The chicken virus is extremely contagious. An infected person can spread it from 1 to 2 days before the rash appears until all blisters have crust over. This means people often spread the virus before they know they are sick.
Chicken pox spreads through airborne respiratory droplets, direct contact with blister fluid, and occasionally through touching contaminated surfaces. In household settings, if one family member gets chickenpox, there’s roughly around 90% chance that non-immune family members will also become infected, or stay at a distance or in a different room.

The Varicella Vaccine: How It Works
The chickenpox vaccine contains a weakened (attenuated) form of the varicella zoster virus. When administered, it triggers your immune system to produce antibodies without causing the actual disease. If you’re later exposed to chickenpox, your immune system recognises the virus and fights it off.
The vaccine is highly effective. Two doses provide about 98% protection against severe chickenpox and about 90% protection against any chickenpox infection.
Benefits of Getting Vaccinated
- Prevention of chickenpox: You significantly reduce your chances of getting the disease.
- Reduced severity if infected: Breakthrough cases in vaccinated people are typically much milder fewer blisters and a shorter duration.
- Protection against complications: Vaccination dramatically reduces the risk of pneumonia, bacterial skin infections, and hospitalisation.
- Community protection: High vaccination rates protect those who can’t be vaccinated, like infants and immunocompromised individuals.
- Lower risk of shingles: Research suggests vaccinated people may have a lower shingles risk later in life compared to those who had a natural infection.
Who Should Get the Chickenpox Vaccine?
- Children: Two doses recommended first at 12-15 months, second at 4-6 years.
- Adolescents and adults who haven’t had chickenpox: Two doses, given 4-8 weeks apart.
- Healthcare workers: To protect themselves and vulnerable patients.
- Teachers and childcare workers: Regular contact with children increases exposure risk.
- Women planning pregnancy: Get vaccinated at least one month before conception. The vaccine should not be given during pregnancy.
- International travellers: Chickenpox remains common in many countries.
- Household contacts of immunocompromised people: Helps protect vulnerable family members.

Who Should NOT Get the Vaccine?
The varicella vaccine is not recommended for:
- Pregnant women
- People with severe allergies to vaccine components
- Individuals with severely weakened immune systems
- People currently ill with moderate to severe acute illness (vaccination should be postponed)
If you’re unsure whether vaccination is appropriate for you, consult a healthcare provider.
What is the difference between Smallpox and Chickenpox?
These diseases are sometimes confused because both cause skin rashes with blisters. However, they’re caused by completely different viruses. Smallpox (caused by variola virus) was far more severe, with a 30% mortality rate and has been eradicated worldwide since 1977.
Chickenpox (caused by varicella zoster virus) is generally milder but remains common. The rashes also differ; chickenpox blisters appear in crops at different stages, while smallpox lesions all develop simultaneously.
Chicken Pox Prevention Beyond Vaccination
While vaccination is the most effective chicken pox prevention strategy, additional precautions help: isolate infected individuals until all blisters crust over, practice good hand hygiene, avoid sharing personal items, and keep fingernails short to reduce scratching damage.

FAQs
- What causes chickenpox?
The varicella zoster virus causes chickenpox, a member of the herpesvirus family. It spreads through respiratory droplets and direct contact with blister fluid from infected individuals. - Is chickenpox contagious?
Yes, extremely. Chickenpox is one of the most contagious diseases known. An infected person can spread it from 1-2 days before the rash appears until all blisters have scabbed over. - How to cure chicken pox fast?
No cure speeds up the infection itself. Chicken pox treatment focuses on symptom relief: calamine lotion for itching, paracetamol for fever (avoid aspirin in children), cool baths, and keeping nails trimmed. Antiviral medication for chickenpox may be prescribed for high-risk individuals if started early. - Can adults get chickenpox?
Yes. Adults who have never had chickenpox or weren’t vaccinated can contract the disease. Chickenpox in adults is typically more severe than in children, with higher rates of complications. - How long does chickenpox last?
The illness typically lasts 5-10 days. New blisters stop forming after about 5 days, and most scabs fall off within 1-2 weeks. Full recovery of chicken pox marks may take several weeks to months. - Is the chickenpox vaccine safe?
Yes. The varicella vaccine has an excellent safety record spanning decades of use. Common side effects are mild soreness at the injection site, low-grade fever, or a small rash. Serious adverse effects are extremely rare.
