Two in Africa to treat Ebola patients because the United States is infected health care workers, after careful treatment, recently discharged. So, if they have the immunity to Ebola?
Experts are careful to say that they should have for Ebola virus infection of that type that is most vicious Zaire type of immunity, but can not promise that. Several other cases of Ebola virus immunity is unknown.
Why do not you verify? Afraid, because the risk is too big, not moral.
The current Ebola epidemic, the survival rate of infection by 47%, that is, less than half the chance of survival. So how can it become the 47%?
The two Americans exactly how healing, it is difficult conclusion, the future is still difficult to specify. Among them one who received the healing serum, they also accepted the experimental drug therapy, and received the most advanced medical care, hard to say what makes them heal.
Ebola epidemic, the mortality rate from the beginning sensational 90%, now 53%, indicating a problem: the importance of medical care. Although there is no effective treatment, but through high-quality medical care, it can save a lot of lives and even the majority of patients. This is the yellow fever, bird flu and other deadly infectious diseases have been repeatedly demonstrated. Ebola patients previously infected areas with high mortality because of poor medical standards affected areas. Currently, global cooperation to go all out for Ebola patients, medical care, Ebola mortality will decline further. This is the merit of international assistance, including doctors is the result of various countries, including China doctors risked their lives of dedication.
Ebola It is a major cause of poor in Africa rampant medical standards and health conditions poor, so two US patients most likely to benefit from advanced medical care. This is the risk of Ebola Survival Guide The first and most important point.
Cured whether they have immunity, the evidence is capable of neutralizing the presence of Ebola virus antibodies in serum were recovered. In the present case, given that infected serum is a last resort, but did not undergo any tests to prove that it works. To date, no cure were again exposed to Ebola virus of any information in, it is impossible to determine whether it has immunity and can not know whether such immunity immune to other types.
Immune function in the fight against Ebola seem to have some effect. Ebola virus and HIV is somewhat similar to the human body after infection kills CD4 and CD8 lymphocytes. If the infected person's immune function is very strong, in the Ebola virus attack, if also left many CD4 CD8 lymphocytes, and patient survival chance will be greater. Conversely, if the immune function out of control, the virus will release inflammatory molecules such broken capillaries, blood pressure, multiple organ failure, and even death.
At the genetic level also seems to have some relevance. A 2007 study found that human leukocyte antigen B of different variations and related Ebola patient survival. There is a higher mortality rate after the B * 07 and B * 14 variant of human infection with Ebola virus a high survival rate, while B * 15 and B * 65 variant of human infection with Ebola virus.
Even more amazing is that there is a gene variation called NPC1 in vitro experiments to achieve tolerance to the Ebola virus, it will not be infected. We have this mutated human cells can not be infected with Ebola virus, but has not done nor do human trials.
This variation in Europeans ratio is 1: 300 to 1: 400, can be quite low. However, up to 1 in Nova Scotia, Canada residents: 10 to 1:26. The place from Ebola epidemic areas far enough, and this variation and evolution Ebola epidemic is not associated with screening. For NPC1 variation Africans data has not been studied.
These points have a great risk of the above, chances are no matter if there is danger. Ebola Survival Guide The most important thing is prevention - to do everything possible not to be infected with Ebola virus.
Prevention is the most likely original vaccine, but Ebola vaccine has not been developed. In fact, for this regional epidemic deadly infectious diseases, do not have to vaccinate against yellow fever is an example. Yellow fever mortality rate is also high, but only popular in parts of Africa and the Americas, has been effective even if the yellow fever vaccine, there is no universal vaccination, and only to the affected areas before vaccination. So, although there is no Ebola vaccine, the infected areas it wants to go.
Ebola virus, although fierce, but the ability to spread is not strong, experts believe that is unlikely to spread through the aircraft. Ebola prevention health measures are relatively simple, does not take contact with body fluids of patients, no contact Wildlife primates and bats, and other measures to wash their hands on it.
