Monkeypox and Chickenpox

Monkeypox and Chickenpox 10 Best Difference

Introduction of Monkeypox and Chickenpox

In the realm of infectious diseases, it is vital to accurately identify and diagnose conditions to ensure proper treatment and containment. Among viral infections, two illnesses, Monkeypox and Chickenpox, while sounding similar, are notably distinct in terms of causative agents, symptoms, and global health impact. This article delves deep into these two diseases, detailing their differences and highlighting why distinguishing between them is of paramount importance.

Definition of Monkeypox

Monkeypox is a rare and contagious viral disease caused by the monkeypox virus, a member of the Orthopoxvirus genus. First identified in monkeys in 1958, the disease was later discovered in humans in the Democratic Republic of the Congo in 1970. Presenting with flu-like symptoms including fever, headache, and muscle aches, the distinguishing feature of monkeypox is a pustular rash that spreads across the body.


While the disease shares some clinical similarities with smallpox, it is generally milder in nature. Transmission to humans typically occurs through direct contact with infected animals, particularly rodents, or through human-to-human transmission. Predominantly found in Central and West Africa, monkeypox has the potential to cause severe health complications, particularly in those with weakened immune systems.

Definition of Chickenpox

Chickenpox is a highly contagious viral infection caused by the varicella-zoster virus (VZV). It’s characterized primarily by the onset of a blister-like rash that appears first on the face and trunk, then spreads over the body. Along with the rash, individuals infected with chickenpox may experience fever, fatigue, headache, and loss of appetite.


Typically seen in children, chickenpox was once a common illness before the introduction of the varicella vaccine. While the disease is usually mild in children, complications can arise, and it can be more severe in adults, leading to issues such as pneumonia, encephalitis, and bacterial skin infections. After recovery, the varicella-zoster virus remains dormant in the body and can reactivate later in life to cause shingles.

Causes of Monkeypox and Chickenpox


  • Causative Agent: Caused by the Monkeypox virus, a member of the Orthopoxvirus genus.
  • Transmission: Typically transmitted to humans from rodents, primates, or through direct human-to-human contact.


  • Causative Agent: Caused by the Varicella-Zoster Virus (VZV).
  • Transmission: Highly contagious, spread easily through airborne droplets when an infected person coughs or sneezes. It can also be contracted by touching the rash or through contact with fluid from blisters.

Symptoms of Monkeypox and Chickenpox


  1. Fever
  2. Headache
  3. Muscle aches
  4. Fatigue
  5. Swollen lymph nodes
  6. Rash: Begins as papules, then turns into vesicles followed by pustules.


  1. Fever
  2. Fatigue
