Chickenpox, also known as varicella, is a highly contagious illness caused by the varicella-zoster virus (VZV). It's most commonly a childhood disease. While typically mild, chickenpox can be more severe in adults, pregnant women, or individuals with weak immunity. Even though there is no specific treatment, by taking certain steps one can manage its symptoms. Read on to know more.
Recognising the early signs of chickenpox is essential for prompt action and minimising discomfort. The health issue typically progresses through several distinct stages, each with its own characteristics.
In the initial phase, individuals may experience:
• Mild fever
• Fatigue
• Loss of appetite
• Headache
• Muscle aches
These symptoms often appear 1-2 days before the tell-tale rash develops.
• The appearance of an itchy rash is the most recognisable symptom of chickenpox. The rash typically starts on the face, chest, and back before spreading throughout the body. It might also appear on the eyelids or genitals. The severity of the rash can vary from person to person.
• The initial red bumps develop into chicken pox blisters (i.e., fluid-filled blisters). These blisters take 3-5 days to crust over and heal, with some healing faster than others.
Over the next few days, new spots continue to appear while existing ones progress through various stages:
• Raised, itchy, red bumps
• Fluid-filled blisters
• Cloudy blisters
• Crusting and scabbing
As the blisters burst or are scratched open, they form crusty scabs. This stage typically begins around day 6 or 7 of the illness and lasts several days until the scabs fall off naturally.
Important Note: Symptoms of chickenpox in adults can be more severe than in children. Adults might experience high fever, a more widespread rash, and a greater risk of complications. Additionally, adults who haven't had chickenpox as children may not develop the classic rash pattern.
Typically, a doctor can diagnose chickenpox based solely on the physical examination of the rash. The widespread, itchy blisters on the face, body, and sometimes even scalp are a strong indicator.
In some cases, additional tests might be needed for confirmation, especially if the rash appears atypical.
• Blood Test: A simple blood test can check for immunity to the varicella-zoster virus, revealing whether a person has previously had chickenpox or received the vaccine.
• Fluid Sample Analysis (rare): A fluid sample extracted from a blister might be sent to a lab for analysis. This helps diagnose chickenpox disease and rule out other conditions with similar blistering rashes.
There is no specific treatment for chickenpox stages. The virus usually runs its course within a week or two, and the body's immune system fights it. However, certain measures can help alleviate symptoms and promote healing —
• Encourage plenty of rest to support the immune system.
• Ensure adequate fluid intake to prevent dehydration.
• Keep nails short to minimise skin damage from scratching.
• Wear loose, soft clothing to reduce irritation.
• Use cool, damp compresses to soothe itchy skin.
• Take lukewarm baths with colloidal oatmeal.
• Apply calamine lotion to itchy areas.
• Use antihistamines to reduce itching and improve sleep.
• Use appropriate fever-reducing medications as recommended by a healthcare provider.
• Avoid aspirin in children and teenagers due to the risk of Reye's syndrome.
• Offer soft, cool foods if mouth sores are present.
• Encourage a balanced diet to support healing.
• Try baking soda baths to relieve itching.
• Apply honey to sores to promote healing (only for children over 12 months).
• Keep affected individuals at home until all blisters have crusted over.
• Avoid scratching to prevent scarring and secondary infections.
• Practice good hand hygiene.
While most cases of chickenpox resolve without complications, it's important to consult a doctor if you experience any of the following:
• High fever (above 39°C) persisting for more than a few days
• Shortness of breath
• Severe headache or vomiting
• Signs of infection around the blisters (such as redness, swelling, and pus)
• Dehydration symptoms (dizziness, lightheadedness)
• Pregnant women who suspect they have chickenpox should seek immediate medical advice.
Fortunately, there's a highly effective way to prevent chickenpox: vaccination. The chickenpox vaccine boasts a success rate of around 90% in preventing the disease for most people.
The standard approach involves two doses of the vaccine. The first dose is typically administered between 12 and 15 months of age, followed by a second dose between 4 and 6 years. This vaccination schedule applies to both children and adults 12 months and older who haven't had chickenpox or received the vaccine previously.
There are two primary vaccines to consider —
• Varivax: This vaccine specifically targets chickenpox.
• ProQuad: This combination vaccine offers protection against four diseases — measles, mumps, rubella, and chickenpox (MMRV). While offering broader protection, ProQuad is typically only given to children aged between 12 months and 12 years.
In addition to vaccination, practising good hygiene and avoiding contact with infected individuals can further reduce the risk of contracting chickenpox.
Chickenpox typically resolves on its own. However, understanding the chickenpox stages and the associated symptoms can help you identify the illness and take steps to manage the discomfort. Remember, avoiding contact with infected individuals and maintaining good hygiene can prevent the spread of chickenpox. If you have any concerns or experience severe symptoms, consulting a doctor is always advisable.
