Almost all people of all ages suffer from chickenpox at least once in their lives. Thus, knowing the causes of chickenpox becomes of utmost importance — whether we are remembering our childhood, helping our children through it, or just staying informed. Knowing the signs or symptoms also allows you to seek timely medical intervention. Here, we will explore the causes of chickenpox, so you have a clearer understanding as to why it occurs and think of preventive measures.

How is Chickenpox caused?

  • Chicken pox is caused by the varicella-zoster virus. This virus is highly contagious, and through coughing or sneezing, it can easily pass from one person to another.
  • The ailment can also be transmitted by touching the chickenpox rash or things/surfaces a person diagnosed with the illness has touched.
  • The virus, varicella-zoster, enters our bodies through our breathing system and travels through our blood. It finally manifests as red spots or blisters on our skin.
  • Chickenpox is usually accompanied by symptoms like fever, fatigue, and itching.

But here’s the good news: chickenpox is generally a one-time deal. In rare cases, it occurs twice as once you’ve had it, your body builds immunity. Do remember that chickenpox affects everyone differently, with some having mild symptoms and others experiencing more severe signs.

Conclusion

Some cases of chickenpox may become severe. If you experience rash in one or both eyes, the rash turns tender due to a bacterial infection, or you feel dizzy, have a stiff neck, feel breathless, develop a cough that worsens over time, and have a high fever (more than 38.9 C or 102 F), it’s time to consult a medical practitioner without delay. Also, consult your doctor if someone at home is pregnant or has never had the ailment before and has never been vaccinated. A health insurance plan can help cover consultation fees, medications, and hospitalization if needed, ensuring you receive timely medical care for severe cases of chickenpox without financial worries.
