But the mystery threat has not been placed on the list to scare the public.
Another disease named by the scientists as disease X gets added to the list of the epidemic infections that spread around the world. So what, exactly, is Disease X? World Health Organization released the list of diseases in December 2015.
At any given time, a potentially deadly global pandemic could explode and destroy a large part of humanity.
Other diseases listed in the report include crimean-congo haemorrhagic fever (cchf), Ebola virus disease, Marburg virus disease, Lassa fever, middle east respiratory syndrome coronavirus (mers-cov), severe acute respiratory syndrome (SARS). nipah and henipaviral diseases, rift valley fever (rvf) and zika virus.
"Disease X represents the knowledge that a serious worldwide epidemic could be caused by a pathogen now unknown to cause human disease, and so the R&D Blueprint explicitly seeks to enable cross-cutting R&D preparedness that is also relevant for an unknown "Disease X" as far as possible", said World Health Organization in a statement.
This is the first time that Disease X has made the list, during a convention of experts on viruses, bacteria and infectious diseases. "Just the way we didn't anticipate Zika, we didn't think there would be an Ebola that would hit cities".
Today, the United Nations organizationis talking about "disease X", a contagious and deadly disease that does not yet exist. However, he stressed that this was to "make sure we prepare and plan flexibility in terms of vaccines and diagnostic tests".
World Health Organization committee scientific adviser John-Arne Rottingen believes the next major outbreak of disease will be something humanity has not seen before. "We want to see "plug and play" platforms developed which will work for any, or a wide number of diseases; systems that will allow us to create countermeasures at speed", he added.
The most likely source of Disease X would be a zoonotic transmission, where a disease spreads from an animal to a human. "It is vital that we are aware and prepare". This has also brought us in closer contact and closer contact with more species of animals than ever before, exponentially increasing the likelihood of zoonoses.
"For numerous diseases discussed, as well as many other diseases with the potential to cause a public health emergency, there is a need for better diagnostics", said the experts who convened in Geneva to gather the report. It's probably the biggest risk.
