Monkeypox Disease

Focus: GS II- Health

Why in News?

The first case of monkeypox was confirmed in India on July 14, after a person who had returned to Kerala from abroad developed symptoms of the disease.

About Monkeypox:

  • Monkeypox is a viral zoonotic disease with symptoms similar to smallpox, although with less clinical severity.
  • The CDC’s monkeypox overview says the infection was first discovered in 1958 following two outbreaks of a pox-like disease in colonies of monkeys kept for research — which led to the name ‘monkeypox’.

Zoonotic disease

  • Monkeypox is a zoonosis, that is, a disease that is transmitted from infected animals to humans.
  • According to the WHO, cases occur close to tropical rainforests inhabited by animals that carry the virus.
  • Monkeypox virus infection has been detected in squirrels, Gambian poached rats, dormice, and some species of monkeys.
  • Human-to-human transmission is, however, limited — the longest documented chain of transmission is six generations, meaning the last person to be infected in this chain was six links away from the original sick person, the WHO says.
Transmission:
  • Transmission, when it occurs, can be through contact with bodily fluids, lesions on the skin or on internal mucosal surfaces, such as in the mouth or throat, respiratory droplets and contaminated objects.

Symptoms and treatment

  • According to the US Centers for Disease Control and Prevention (CDC), monkeypox begins with a fever, headache, muscle aches, back ache, and exhaustion.
  • It also causes the lymph nodes to swell (lymphadenopathy), which smallpox does not.
  • The WHO underlines that it is important to not confuse monkeypox with chickenpox, measles, bacterial skin infections, scabies, syphilis and medication-associated allergies.
  • The incubation period (time from infection to symptoms) for monkeypox is usually 7-14 days but can range from 5-21 days.
  • Usually within a day to 3 days of the onset of fever, the patient develops a rash that begins on the face and spreads to other parts of the body.
  • The skin eruption stage can last between 2 and 4 weeks, during which the lesions harden and become painful, fill up first with a clear fluid and then pus, and then develop scabs or crusts.
  • According to the WHO, the proportion of patients who die has varied between 0 and 11% in documented cases, and has been higher among young children.
Treatment:
  • There is no safe, proven treatment for monkeypox yet.
  • The WHO recommends supportive treatment depending on the symptoms.
  • Awareness is important for prevention and control of the infection.

Occurrence of disease

  • The CDC’s monkeypox overview says the infection was first discovered in 1958 following two outbreaks of a pox-like disease in colonies of monkeys kept for research — which led to the name ‘monkeypox’.
  • The first human case was recorded in 1970 in the Democratic Republic of the Congo (DRC) during a period of intensified effort to eliminate smallpox.
  • According to the WHO, 15 countries on four continents have so far reported confirmed cases of monkeypox in humans.
  • Locally acquired cases have been confirmed in the DRC (which has the largest incidence of the infection in the world), Central African Republic, Republic of the Congo, Gabon, Cameroon, Nigeria, Côte d’Ivoire, Liberia, and Sierra Leone.
