Ebola..What's that?
It's simply a virus of the filoviridae family who which causes a severe fever or viral haemorrhagic fever (VHF).
It is a single-stranded RNA virus of negative polarity and with a non-segmented genome. It has a filamentous appearance.
There are six viral species inside the Ebolavirus:
ebolavirus Bundibugyo Bundibugyo Ebolavirus
Ebolavirus TaĂŻ Forest Tai Forest Ebolavirus
Ebolavirus Reston Reston Ebolavirus
ebolavirus Sudan Sudan ebolavirus
Ebolavirus Zaire Zaire Ebolavirus
Ebolavirus Bombali Bombali Ebolavirus
constitution Composition
He It can be linear or branched ,0.8 to 1 micrometer long but up to 14 micrometer by concatererization ( formation of a long particle with particles more courtesy Je n'ai pas compris le dernier mot ),with a constant diameter of 80 nm. It has a helical nuclear capsid of 20 to 30 nm in diameter. This consists of NP and vP30 nucleoproteins, itself is enveloped in a helical matrix 40 to 50 nm in diameter made up of proteins VP24 and VP40 and comprising of transverse streaks of 5 nm. The whole thing , is in turn, enveloped in a lipid membrane in which GP (glycoproteins) are inserted.
It has a 19 kilobase genomes with an organization characteristic of filoviruses. This genome encodes nine functional proteins on seven genes expressed as follows.
Is it a disease like the others? Who is attacked?
The Ebola virus was discovered in 1976 towards near the river in the DRC (Democratic Republic of the Congo). He It killed 431 people, then the epidemics followed one another: the one in 2014, which seems to be the most serious epidemic , started in February and has already killed more than ??? Il manque le chiffre ici people seven months later(at least 28,000 cases for more than 11,000 deaths). Efforts to combat the epidemic have gradually made it possible to reduce transmission and, since March 2015, to limit its expression spread to minor outbreaks. Maintaining significant surveillance is essential.
Unfortunately, it's a very serious ,contagious,potentially fatal disease…. In addition to that,there is NO TREATMENT that could cure Ebola fever nor is there a licensed vaccine to prevent this it. However ,the purpose of the care provided is to combat the symptoms caused by the disease and to help the patient survive the infection.
It can affect any person ,men,women ,younger like older…. young and old alike. Experts do not even know why some people survive and others not. Recovered people People who have had it and who have recovered can spread the virus up to 7 weeks after recovery and , deceased people. dead people can also transmit the disease.This is strange but true.
Again and again..
BATS ,they can transmit a lot of viruses like (covid-19) to other animal ,such as monkeys..
Men People can be infected too, via these animals (contact with their blood,by their meat etc..). Then, transmission to humans during epidemics occurs humans .(objects contamined with the virus like clothing etc.)
What are the symptoms of the Ebola virus?
The Ebola virus onmy spreads after the onset of symptoms,wich which begins after an incubation period of 2 to 21 days.
.Sudden onset of fever
.Weakness and muscle pain
.Headache
.Throat irritation
.Vomiting and diarrhea
.Kidney and liver failure
.Internal and external bleeding(in some cases)
Diagnostic
Ebola viral hemorrhagic fever is very difficult to diagnose. First,because the first symptoms can ressemble other illnesses such as Malaria, or Cholera, or food poisoning.
Second, because it's almost impossible to carry out blood tests in the regions concerned…there is no high security laboratory on the ground. The presence of the Ebola virus is indeed confirmed following various blood tests such as Elisa test.
It's therefore very important to know whether the person has been in contact with a person infected in the previous 3 weeks or whether he or she participated in a funeral by touching the deceased person in the previous 3 weeks.
The real question is Do we have an effective treatment ?
No! patients receiving receive care to relieve their symptoms, for example :
•Supportive care in the intensive care unit
• Maintaining the level of liquids and electrolytes
•Maitaining oxygen saturation and blood pressure
•Replacement of lost blood and clotting factors
•Strict isolation to prevent transmission of the virus
Can Ebola virus disease be prevented?
Yes you can protect yourself from Ebola infection by applying specific prevention and control measures,like washing your hands, avoiding contact with body fluids in suspected or confirmed cases of Ebola, and by refraining from manipulator or prepare the bodies of the deceased if the Ebola virus is the suspected or proven cause of death.
Caregivers should wear gowns, gloves , masks and glasses. And do not reuse the syringes.
Particular attention must be paid during funeral rites because the deceased are still carriers of the virus and can be contagious.
You have to learn not to put your hand on your mouth or near your eyes, the gateway to the virus.
Wear gloves and protective clothing when handling sick animals and their flesh.
Stay alert in cured patients who can still transmit the virus for 7 weeks. They should avoid sex during this time or use a condom.
