Ebola virus can not be cured, there is no vaccine against it. Because the vaccine must be specific for a particular strain, it is impossible to produce a universal vaccine for all four vaccines. There are many factors that can cause Ebola occurrence. . Below is a list of conditions that could lead to such devastating events. - Animals and insect vectors are present near the population - Exposing viruses to individuals in remote areas and returning individuals to areas with high population - The sanitary condition of the population is poor, hygiene is bad, Exposure increases (eg:
Currently, there is no Ebola treatment approved (in addition to treatment of highly experimental treatments and symptoms), there is no cure at present. The Ebola vaccine developed since the epidemic in West Africa in 2014 is offered in limited quantities in emergency situations; the WHO and the Democratic Republic of the Congo have agreed to use this vaccine against the current epidemic . Ebola virus is one of the most deadly infectious diseases we know and about 50% of infected people are estimated to die (estimated mortality rate). Nonetheless, the number of deaths may differ due to outbreaks, and in Ebola the proportion of outbreaks in the past ranged from 25% to 90%. The mortality rate of other diseases including seasonal influenza (<1%) and SARS (13-43%) is much lower
The occurrence of infections like Ebola requires immediate action. Ebola virus quickly becomes fatal and there are few treatment options. When experimental treatment may be your only hope to save your life and stop the epidemic, you will not do RCT. You will not detain this treatment from patients who are essentially Russian roulette at random. You will give it to everyone. In the absence of other treatments, researchers can conduct observational research without control. Everyone in the observational study received treatment, and researchers observed the results. The only drawback is that there is no comparison. Therefore, it is difficult to exclude other variables on the screen.
