I'm sorry for any confusion, but "Gabon" is not a medical term. It is the name of a country located in Central Africa, known officially as the Gabonese Republic. If you have any questions about medical terminology or health-related topics, I would be happy to help with those!

Central Africa is a geographical region that broadly includes the countries that lie near the equator and are found in the interior of the African continent. The United Nations defines Central Africa as consisting of the following countries: Angola, Burundi, Cameroon, Central African Republic, Chad, Democratic Republic of the Congo, Republic of the Congo, Equatorial Guinea, Gabon, Rwanda, and Sao Tome and Principe.

The region is characterized by diverse cultures, languages, and landscapes, ranging from dense rainforests to vast savannas. Central Africa is home to many important rivers, including the Congo River, which is the second longest river in Africa and the deepest river in the world. The region also contains numerous national parks and wildlife reserves that protect a diverse array of plant and animal species, including several endangered species such as mountain gorillas, chimpanzees, and forest elephants.

Central Africa faces many challenges, including political instability, poverty, and environmental degradation. The region has been plagued by conflicts and civil wars, which have resulted in significant loss of life, displacement of people, and destruction of infrastructure. Climate change and deforestation are also major concerns, as they threaten the region's biodiversity and contribute to global warming.

In terms of healthcare, Central Africa faces many challenges, including a high burden of infectious diseases such as HIV/AIDS, malaria, tuberculosis, and Ebola. Access to healthcare is limited in many areas, particularly in rural communities, and there is a shortage of healthcare workers and medical facilities. In addition, the region has been affected by conflicts and humanitarian crises, which have further strained healthcare systems and made it difficult to provide adequate care to those in need.

Ebola Hemorrhagic Fever (EHF) is a severe, often fatal illness in humans. It is one of the five identified subtypes of the Ebolavirus. The virus is transmitted to people from wild animals and spreads in the human population through human-to-human transmission.

The early symptoms include sudden onset of fever, fatigue, muscle pain, headache and sore throat. This is followed by vomiting, diarrhea, rash, symptoms of impaired kidney and liver function, and in some cases, both internal and external bleeding.

Laboratory findings include low white blood cell and platelet counts and elevated liver enzymes.

The virus is introduced into the human population through close contact with the blood, secretions, organs or other bodily fluids of infected animals such as fruit bats, porcupines and non-human primates. Then it spreads in communities through human-to-human transmission via direct contact (through broken skin or mucous membranes) with the blood, secretions, organs or other bodily fluids of infected people, and with surfaces and materials contaminated with these fluids.

Healthcare workers have frequently been infected while treating patients with suspected or confirmed EVD due to a lack of adequate infection prevention and control measures.

There are currently no approved specific antiviral drugs or vaccines for Ebola. Several promising treatments and vaccine candidates are being evaluated.

I'm not aware of a specific medical term called "Ape diseases." However, many primates, including apes, can suffer from diseases that are similar to those that affect humans. Some examples include:

1. Tuberculosis (TB): Both humans and apes can be infected with this bacterial disease, which primarily affects the lungs but can also impact other parts of the body.
2. Hepatitis: Apes can contract various forms of hepatitis, such as hepatitis B and C, just like humans. These viral infections affect the liver and can cause acute or chronic illness.
3. Respiratory infections: Both apes and humans are susceptible to respiratory infections caused by bacteria, viruses, or fungi.
4. Gastrointestinal diseases: Apes can suffer from gastrointestinal issues, such as diarrhea, due to various bacterial, viral, or parasitic infections.
5. Retroviral infections: Some apes are known to be infected with retroviruses, like simian immunodeficiency virus (SIV), which is similar to human immunodeficiency virus (HIV). SIV can lead to a condition called simian AIDS in apes.
6. Zoonotic diseases: Apes can contract zoonotic diseases, which are transmitted from animals to humans, such as Ebola and Marburg viruses.
7. Cardiovascular diseases: Apes can develop heart conditions similar to those seen in humans, including hypertension and atherosclerosis.
8. Neurological disorders: Some apes may suffer from neurological issues, like Parkinson's disease or Alzheimer's disease, although research on these topics is still ongoing.

It's important to note that while apes can contract many of the same diseases as humans, there are also numerous diseases specific to each species due to differences in genetics, environment, and behavior.

"Mandrillus" is a genus of primates that includes two species: the mandrill (M. sphinx) and the drill (M. leucophaeus). These Old World monkeys are native to the rainforests of central Africa, particularly in Cameroon, Gabon, Equatorial Guinea, and Congo.

Mandrills are known for their distinctive appearance, with males having brightly colored faces and rear ends. They are also the largest and most sexually dimorphic monkeys, with males being significantly larger and more brightly colored than females.

Mandrills are primarily frugivorous, feeding on a diet that consists mainly of fruits, but they also eat other plant materials, insects, and occasionally small vertebrates. They live in large, hierarchical groups called troops, which can consist of several hundred individuals.

Mandrills have a complex social structure, with males competing for dominance and access to females. They are known for their loud, distinctive calls, which can be heard up to a mile away and are used to communicate with other members of their troop.

Overall, Mandrillus species are important indicators of the health and diversity of tropical rainforests in central Africa, and they play a critical role in seed dispersal and forest regeneration.

Loiasis is a tropical parasitic infection caused by the filarial nematode worm, Loa loa. It is also known as "African eye worm" due to the migration of the adult worm through the subconjunctival tissues of the eye, which is a common symptom. The infection is transmitted through the bite of deerfly or mango fly (Chrysops spp.).

After transmission, the larval form of the parasite migrates through the soft tissues and matures into an adult worm that lives in the subcutaneous tissue. Adult worms can be up to 7 cm long and may cause localized itching or a transient subconjunctival migration, which is painless but alarming to the patient.

Loiasis is usually asymptomatic, but severe symptoms such as Calabar swellings (recurrent angioedema), arthralgia, pruritus, and cardiac or respiratory complications can occur in heavy infections. Diagnosis is made by detecting microfilariae or adult worms in the blood, skin snips, or eye fluid. Treatment typically involves diethylcarbamazine citrate (DEC) therapy, but ivermectin and albendazole can also be used. Preventive measures include avoiding fly bites through the use of protective clothing, insect repellents, and bed nets.

Ebolavirus is a genus of viruses in the family Filoviridae, order Mononegavirales. It is named after the Ebola River in the Democratic Republic of Congo (formerly Zaire), where the virus was first identified in 1976. There are six species of Ebolavirus, four of which are known to cause disease in humans: Zaire ebolavirus, Sudan ebolavirus, Bundibugyo ebolavirus, and Tai Forest ebolavirus (formerly Cote d'Ivoire ebolavirus). The fifth species, Reston ebolavirus, is known to cause disease in non-human primates and pigs, but not in humans. The sixth and most recently identified species, Bombali ebolavirus, has not been associated with any human or animal diseases.

Ebolaviruses are enveloped, negative-sense, single-stranded RNA viruses that cause a severe and often fatal hemorrhagic fever in humans and non-human primates. The virus is transmitted to people from wild animals and spreads in the human population through human-to-human transmission. Fruit bats of the Pteropodidae family are considered to be the natural host of Ebolavirus.

The symptoms of Ebolavirus disease (EVD) typically include fever, severe headache, muscle pain, weakness, fatigue, and sore throat, followed by vomiting, diarrhea, rash, impaired kidney and liver function, and in some cases, both internal and external bleeding. The case fatality rate of EVD is variable but has been historically high, ranging from 25% to 90% in past outbreaks depending on the species and the quality of medical care. There are no licensed specific treatments or vaccines available for EVD, although several promising candidates are currently under development.

Malaria, Falciparum is defined as a severe and often fatal form of malaria caused by the parasite Plasmodium falciparum. It is transmitted to humans through the bites of infected Anopheles mosquitoes. This type of malaria is characterized by high fever, chills, headache, muscle and joint pain, and vomiting. If left untreated, it can cause severe anemia, kidney failure, seizures, coma, and even death. It is a major public health problem in many tropical and subtropical regions of the world, particularly in Africa.
