A new case of Ebola Fever has been reported in the Democratic Republic of Congo, according to the World Health Organization. The patient, described as an adult female, presented at a health clinic in the Biena Health Zone with bleeding from the nose on 25 January 2021, where she was treated as an outpatient. However, on 4 February she was admitted to a second health clinic suffering from physical weakness, dizziness, joint pain, epigastric pain, liquid stools, headache and difficulty breathing, and subsequently died the following day in an intensive care unit in Butembo city. Tests carried out at the hospital provided a positive result for Ebola Fever Virus. Local health authorities are now trying to contact 117 people identified as having been in contact with the patient.
Ebola Haemorrhagic Fever is caused by RNA Viruses of the genus Ebolavirus. It has a reputation for being the world's deadliest viral disease, at least in part due to the 1995 film Outbreak, though this is probably slightly inaccurate as about 50% of victims survive, making it less deadly than diseases such as Rabies. However, it is extremely contagious, with know known cure, and has a tendency to rapidly overwhelm local health systems as health workers themselves are infected.
Ebola begins with a fever similar to that caused by Influenza or Malaria, which tends to come on rapidly two-to-three weeks after infection (during at least part of which time the patient is already infectious). This tends to be followed by extreme respiratory tract infection, headaches, confusion, rashes and tissue necrosis and heavy bleeding. Death is generally caused by multiple organ failure.
The only known treatment for Ebola is intensive rehydration, which can improve the survival prospects of patients greatly, accompanied by anticoagulants and procoagulants to mange the diseases attacks on the circulatory system, analgesia to cope with the pain of the disease and antibiotics and antimycotics to prevent secondary infection. Due to the highly contagious nature of the disease it is recommended that healthcare workers wear full-body protection to maintain a barrier between them and their patients; a daunting prospect in the tropical regions of Africa where the disease is endemic.
Ebolavirus is thought to have a non-human animal vector, since its rapid onset and high mortality rate appears to preclude a permanent residence within Human hosts. Surveys of wild animals have found Ebola infections in Rodents and Great Apes, however these were affected by the disease in a similar way to Humans, and are therefore unlikely permanent hosts. The most likely vectors are thought to be Fruit Bats or small Primates, which are endemic to the areas where the disease occurs and which are widely eaten; cooking meat probably kills the virus, but there is a distinct danger of infection while preparing carcasses.
