![]() How long this takes is still questionable and part of ongoing research.Ī person may show signs of great improvement within a few weeks of falling ill but may still carry some of the virus in portions of their body, such as in the spinal column fluid, testes (in the semen) or even the eyes (in the ocular fluid). It may thus take some time for the virus to be completely cleared from the body. This is because it is not yet well understood just how much of the virus can remain in certain areas of the body that are not easily reached by the immune system. Precautions are advised even after recovery from the Ebola virus. Recovery from and the transmission risk of Ebola virus disease (EVD) Burial ceremonies in many West African regions involve direct contact with the body of a loved one, placing mourners at a greater risk of infection. The viral level remains high in a person’s bloodstream and various bodily fluids even after death, and any contact that is made with these can still transmit the disease. Transmission is possible during the handling of the body of a person who has died from an Ebola infection.Non-disposable needles and syringes, and other medical equipment have also been known to contribute to disease transmission if not properly sterilised before re-use or if accidental contact occurs. Contact with contaminated surfaces and objects within this timeframe can still transmit the virus, causing infection. The Ebola virus is capable of surviving on surfaces (outside of the body) for several hours at a time. Surfaces and objects, like clothing or bed linens and even countertops and doorknobs can become contaminated by an infected person, and subsequent contact can result in disease transmission. Transmission is also possible through contact that is made between objects and surfaces and the bodily fluids and secretions of an infected person.Caregivers and medical personnel in close contact with infected individuals (without adequate barrier protection) are at high risk of infection themselves. An infected person can transmit the infectious disease via direct contact with bodily secretions and fluids, mucous membranes (like the eyes, nose and mouth) or even broken skin. Direct contact between humans can easily begin spreading the Ebola virus within community populations.Contact is made through the handling of an infected animal which may involve preparations for cooking and consuming it. This is also known as a spill-over event. Direct contact between humans and animals (dead or alive), which can include bats, primates, porcupines and even forest antelope, results in cross-species transmission.Transmission modes of the Ebola virus include: 1. Individuals who prepare bushmeat (sourced from wild animals) for human consumption and fall ill may also be classed as secondary transmission sufferers. Secondary: This typically refers to identified transmission modes involving human-to-human (most often healthcare personnel, family or caregivers falling ill after being exposed to an infected individual while alive or deceased) or primate-to-human contact (usually animal care workers exposed to infected primates).A person may be classified in the primary category if they frequently travel to or reside in an endemic / outbreak area, like the DRC, Gabon, Sudan or Côte d’Ivoire (Ivory Coast), or have a history of exposure in tropical African forests. Primary: This usually refers to a known presence of the Ebola virus in a confirmed endemic / outbreak area.Transmission exposure may be characterised as: The mechanism of transmission is believed to be through direct contact with infected bodily tissues (including organs), substances (like faeces or vomit) and fluids (like that of blood, saliva, mucous, urine, semen, sweat, tears and even breast milk) or mucous membranes of an infected animal.ĭirect contact merely means that people or animals (such as monkey) have inadvertently touched or come into contact with infected substances which then enter their body – often through the mucous membranes of the eyes, nose, mouth or via broken skin (a wound, cut or abrasion). It is agreed that the most likely carrier source of Ebola virus (also referred to as a natural reservoir host) is that of infected bats who can transmit the disease to both human populations and those of non-human primates.
