Rabies: How is it transmitted and affects humans?

After the discovery of at least three possible cases of human rabies in children in Oaxaca, authorities activated epidemiological surveillance protocols. Here we tell you what is this disease, how it spreads and how it affects humans?

what is anger?

Rabies is a viral disease Which is fatal but preventable. The World Organization for Animal Health (OMSA) states that it affects the central nervous system of mammals such as dogs, cats, foxes and even humans.

However, the United States Centers for Disease Control (CDC) states that only a few species act as significant reservoirs of the disease.

How is it transmitted?

rabies virus It is transmitted through direct contact Found mainly in the saliva and brain of infected animalsespecially dogs. However, in some areas bats also represent an important reservoir.

According to the CDC, People usually contract rabies from the bite of a rabid animal. Although rare, it is also possible to contract it through other types of exposure, which can include scratches, abrasions, or open wounds that come into contact with saliva or other potentially infectious material from a rabid animal.

A greater presence of the disease in wild species can create many opportunities for cross-transmission between species, particularly affecting domestic animals and humans.

  • Because it is transmitted from animals to humans, rabies is considered a zoonotic disease (or zoonosis).

symptoms

However, according to OMSA, it is possible that at first symptoms While not specific, these may include:

  • lethargy
  • Fever
  • Vomiting
  • anorexia

However, within a few days, the signs develop into:

  • brain dysfunction
  • ataxia (impaired balance or coordination due to damage to the brain, nerves, or muscles,
  • weakness
  • paralysis
  • difficulty breathing and swallowing
  • excessive salivation
  • abnormal behavior
  • aggression
  • self extinction

incubation period This can range from a few weeks to several months, says the OMSA, but once symptoms of rabies appear, the disease is inevitably fatal in both animals and humans.

Rabies: One of the Deadliest Zoonoses to Exist

according to world organization for animal healthFor more than 4 thousand years, rabies represented a plague in almost all corners of the globe and no attempts were made to eradicate it.

Although rabies has been eradicated in Western Europe, North America, Japan, South Korea, and parts of Latin America, the viral disease is still present in large parts of Africa and Asia.

mostly rabies deaths, In both humans and animals, it is caused by inadequate access to public health resources and preventive treatments, with low-income countries disproportionately affected by the disease.

OMSA statistics show that 99% of human rabies cases are caused by bites from infected dogs.while more 95% deaths from rabies occur in Africa and Asia, most of which 80% occurs in rural areas Limited or no access to health campaigns.

  • 4 out of 10 rabies deaths are children

Global Rabies Overview

with death rate almost 100% in both humans and animals Rabies is a global threat What? kills about 59 thousand people every year, According to OMSA.

According to the organization, Dogs are the main reservoir of this disease. Therefore, controlling and eliminating this deadly zoonosis means combating it at its animal origin. Canine-borne rabies is expected to be eliminated by 2030.
