The World Health Organization (WHO) a week ago convened a gathering of professionals from an array of areas including virology, microbiology and medical medicine, together with the goal of determining five to ten emerging pathogens more likely to trigger severe outbreaks in the foreseeable future.
Consequently of the convention that was used in Geneva, the group has now compiled a list of eight diseases that it suggests should be prioritized by those conducting research and development into the prevention of major outbreaks.
According to Science Insider, the initiative was launched in response to widespread criticism of WHO’s initial response to the Ebola outbreak in West Africa, with one independent panel claiming that the organization was too slow to put measures in place to halt the spread of the disease. To prevent a repetition of the deterioration caused by the Ebola crisis, WHO is now advocating that more be done to produce therapy applications before episodes arise, as opposed to waiting until an urgent situation to start conducting research. Specifically, it’s required goal is to get towards the 8 most dangerous pathogens revealed from the screen in Europe.
Among these is the Crimean-Congo haemorrhagic fever (CCHF), a virus that is transmitted via ticks that feed on livestock, which has a 40 percent mortality rate. At present there is no available vaccine. Also on the list is the Marburg virus, which causes severe haemorrhagic fever and is carried by fruit bats of the Pteropodidae family, but can also be transmitted from human to human.
The Lassa virus, which is prevalent in West Africa, is also included on the list. Though rarely fatal under normal conditions, if contracted by pregnant women death or foetal loss occurs in over 80 percent of cases.
Ebola is another of the pathogens identified by the panel as worthy of priority, as are SARSand MERS, both of which are viral respiratory diseases, and the latter of which has a 36 percent fatality rate.
In addition, the panel has suggested that Rift Valley fever, which can be transmitted by livestock or mosquitos, be included on the list. Though its symptoms are usually mild, a minority of infections result in serious problems such as brain inflammation. Finally, the team have identified Nipah – which has been detected in parts of Asia and generates a range of neurological complications – as worthy of priority by those conducting research and development into the prevention of major outbreaks.
All eight pathogens were selected for their potential to cause serious outbreaks in the near future, combined with the relative paucity of available treatments. For this reason, diseases that currently receive a great deal of attention and funding, such as HIV/AIDS and malaria, were not included.
WHO is now recommending that treatment programs be developed for all eight pathogens, so that these can be rolled out immediately in the case of an outbreak. Such initiatives, it claims, should be directed towards the generation of vaccines as well as improved diagnostic techniques and behavioral responses, which must be adopted when cases of infection are first detected.
