Ebola virus

• In general, Several viruses of the family Filoviridae cause severe and frequently fatal viral hemorrhagic fevers in humans.
• Moreover, Introduction of filoviruses into human populations is an extremely rare event that most likely occurs by either direct or indirect contact with healthy mammalian filovirus hosts or by contact with infected, sick, or deceased nonhuman primates.

The family Filoviridae includes three genera: Cueva virus, Ebolavirus, also Marburg virus

These genomes contain six or seven genes that encode the following seven structural proteins:

nucleoprotein, polymerase cofactor (i.e. VP35), matrix protein (i.e. VP40), glycoprotein (e.g. GP1,2), transcriptional cofactor (VP30), secondary matrix protein (VP24), and RNA-dependent RNA polymerase (L protein). 

• Percutaneous (e.g., needle stick) or mucous membrane exposure to blood or body fluids of EVD patient while the patient was symptomatic
• Exposure to the blood or body fluids (including but not limited to feces, saliva, sweat, urine, vomit, and semen) of a person with Ebola while the person was symptomatic without appropriate personal protective equipment (PPE)
• Processing blood or body fluids of a person with Ebola while the person was symptomatic without appropriate PPE or standard biosafety precautions
• Direct contact with a dead body without appropriate PPE in a country with widespread Ebola virus transmission
• Having lived in the immediate household and provided direct care to a person with Ebola while the person was symptomatic.
• In countries with widespread Ebola virus transmission: direct contact while using appropriate PPE with a person with Ebola while the person was symptomatic
• Close contact in households, health care facilities, or community settings with a person with Ebola while the person was symptomatic. Close contact is defined as being for a prolonged period of time while not wearing appropriate PPE within approximately 3 feet (1 meter) of a person with Ebola while the person was symptomatic.
• Having brief direct contact (e.g., shaking hands) while not wearing appropriate PPE, with a person with Ebola while the person was in the early stage of disease
• Brief proximity, such as being in the same room for a brief period of time, with a person with Ebola while the person was symptomatic
• In countries without widespread Ebola virus transmission: direct contact while using appropriate PPE with a person with Ebola while the person was symptomatic
• Traveled on an aircraft with a person with Ebola while the person was symptomatic. 

Tropism

• Ebola virus infects mainly the cells of the mononuclear phagocyte system, but also fibroblasts, hepatocytes, spongiocytes, adrenal cortical cells and endothelial cells.
• The infection of the mononuclear phagocyte system cells plays a key role in the pathogenesis and spread of the disease as they carry the virus from of the initial infection site, through the lymphatic system and blood, to the regional lymph nodes, spleen and liver.

• Immune response

  • The virus activates the macrophages synthesis of interleukins (IL), which leads the Th1/Th2 balance towards a more pronounced Th1-cell mediated response.
  • Some inflammatory mediators produced during the Ebola virus infection include interferon (IFN)-alpha, IFN-beta, IL-2, IL-6, IL-8, IL-10, interferon-inducible protein 10; monocyte chemoattractant protein 1; regulated upon activation normal T cell expressed and secreted (RANTES); TNF-alpha; and reactive oxygen and nitrogen species.
  • Some viral proteins, such as VP35 and VP24, block the type I interferon response, which plays a key role of the pathogenesis of the disease.
  • The reactive oxygen and nitrogen species contribute to the cell and tissue damage, and therefore vascular and organ damage.
  • The nitric oxide is known to be an important vasodilator; therefore it plays and important role in the development of hypotension and shock.

  Coagulation system

  • Ebola infection is associated with hemorrhage in 50% of patients.
  • Alterations of the coagulation system are induced by the ebola virus, and are thought to be mediated by the production of tissue factor:

  • Consumption of clotting factors
  • Increased concentrations of fibrin degradation products
  • Disseminated intravascular coagulopathy

• The next table summarizes the pathogenesis of the disease according to the virus tropism. 

Zaïre Ebolavirus

• Among the five strains, Zaïre Ebolavirus carries the highest mortality rate.

• It is endemic in Uganda.
• It has a genome with three gene overlaps (VP35/VP40, GP/VP30, VP24/L).
• It has a genomic sequence different from Ebola virus by ≥30%, but different from that of Bundibugyo virus by <30%.

• Aches and pains, e.g. severe headache and muscle and joint pain
• Weakness also fatigue
• Sore throat
• Loss of appetite
• Gastrointestinal symptoms including abdominal pain, diarrhea, also vomiting
• Unexplained either haemorrhaging, bleeding or bruising

Appearance of the Patient

The general appearance of the patient depends on the stage of the disease. Typically, patients demonstrate prostration, may be nauseated and vomiting, and less commonly present with signs of hemorrhage, such as epistaxis or gingival bleeding. In later stages of the disease, patients are often brought with convulsions or are in a state of shock, stupor, or coma.

Vitals

Temperature

• High-grade fever is often present in more than 80% of patients.
  

  Fever is the most common presenting sign of Ebola virus infection.

Pulse

• Tachycardia
• Relative bradycardia

Blood Pressure

• Hypotension (SBP<90 mmHg and/or DBP<60 mmHg)
• Postural hypotension is common in dehydrated patients with inadequate volume repletion

Respiratory Rate

• Signs of respiratory difficulty may be present, such as:

• Intercostal retractions
• Paradoxical breathing
• Nasal flare

• Tachypnea often precedes death during final hours of infection.

Skin

Hemorrhagic manifestations tend to occur during the more severe stages of the disease and may include:

• Maculopapular rash on the trunk, usually between the 5th and 7th day of the condition, associated with different stages of erythema and desquamation, which is a valuable finding in differentiating Ebola from other diseases.
• Petechiae is a common finding
• Ecchymoses is a common finding
• Mucosal hemorrhages is a common finding
• Uncontrolled bleeding from venipuncture locals is a common finding

Eyes

• Conjunctival hemorrhage is a the most common sign of abnormal clotting

• Conjunctivitis

Nose

• Epistaxis may be present.
• Nasal discharge may be present.

Throat

• Mucosal hyperemia of the oral cavity is a common finding.
• Bleeding gums is a common finding.

Abdomen

• Abdominal tenderness may suggest pancreatitis, intestinal swelling, or mesenteric lymphadenopathy
• Abdominal distention may suggest paralytic ileus
• Tender hepatomegaly
• Splenomegaly

Extremities

• Edema may be present.

Neurologic

• Obtundation may be present.
• Stupor

• Coma

• Antigen-capture enzyme-linked immunosorbent assay (ELISA) testing
• IgM ELISA
• Polymerase chain reaction (PCR)
• Virus isolation
• IgM and IgG antibodies
• Immunohistochemistry testing
• PCR
• Virus isolation

• Basically, Filovirus infections cannot diagnose on the basis of clinical presentation alone.
• Acute-phase blood/serum is the preferred diagnostic specimen because it usually contains high titers of filovirions also filovirion-specific antibodies.
• Consequently, diagnostic samples should collect with great caution and with use of proper personal protective equipment and strict barrier nursing techniques.
• In detail, With adherence to established bio safety precautionary measures, samples should sent in suitable transport media to national or international WHO reference laboratories.
• All in all, Direct IgM and IgG or IgM capture ELISA use for the detection of filovirion-targeting antibodies from patients in later stages of disease 

• Shigellosis & other bacterial enteric infections
• Typhoid fever
• Malaria
• Lassa fever
• Yellow fever
• Flaviviridae 

• Avoid contact with blood and body fluids (such as urine, feces, saliva, sweat, vomit, breast milk, amniotic fluid, semen, and vaginal fluids) of people who are sick.
• Avoid contact with semen from a man who has recovered from EVD, until testing shows that the virus is gone from his semen.
• Avoid contact with items that may have come in contact with an infected person’s blood or body fluids (such as clothes, bedding, needles, and medical equipment).
• Avoid funeral or burial practices that involve touching the body of someone who died from EVD or suspect EVD.
• Avoid contact with bats, forest antelopes, and nonhuman primates (such as monkeys and chimpanzees) blood, fluids, or raw meat prepared from these or unknown animals (bushmeat).
• Ebola vaccine is given as a single dose vaccine and has been found to be safe and protective against Zaire ebolavirus, which has caused the largest and most deadly Ebola outbreaks to date.

Given the severe immunosuppression induced by filovirus infection, secondary infections should be kept in mind and appropriately treated as early as possible.

Pregnancy and labour cause severe and frequently fatal complications in filovirus infections due to clotting factor consumption, fetal loss, and/or severe blood loss during birth. 

Homeopathy treats the person as a whole. It means that homeopathic treatment focuses on the patient as a person, as well as his pathological condition. The homeopathic medicines selected after a full individualizing examination and case-analysis. 

Which includes 

• The medical history of the patient, 
• Physical and mental constitution,
• Family history, 
• Presenting symptoms,
• Underlying pathology,
• Possible causative factors etc. 

A miasmatic tendency (predisposition/susceptibility) also often taken into account for the treatment of chronic conditions. 

What Homoeopathic doctors do? 

A homeopathy doctor tries to treat more than just the presenting symptoms. The focus is usually on what caused the disease condition? Why ‘this patient’ is sick ‘this way’? 

The disease diagnosis is important but in homeopathy, the cause of disease not just probed to the level of bacteria and viruses. Other factors like mental, emotional and physical stress that could predispose a person to illness also looked for. Now a days, even modern medicine also considers a large number of diseases as psychosomatic. The correct homeopathy remedy tries to correct this disease predisposition. 

The focus is not on curing the disease but to cure the person who is sick, to restore the health. If a disease pathology not very advanced, homeopathy remedies do give a hope for cure but even in incurable cases, the quality of life can greatly improve with homeopathic medicines. 

Homeopathic Medicines for Ebola virus: 

The homeopathic remedies (medicines) given below indicate the therapeutic affinity but this is not a complete and definite guide to the homeopathy treatment of this condition.
