In 2018, the WHO introduced the concept of Disease X, a previously unknown disease that could cause a massive epidemic.
Some experts are even calling the new strain of coronavirus – ‘disease X’ – a powerful pathogen that could trigger a pandemic with catastrophic consequences. This is what naked-science.ru writes.
Throughout history, some epidemics have killed many people, while others have killed only hundreds.
According to scientists, any germ normally cannot be a perfect killer, as it is bound to die on its own because its habitat disappears. In addition, the immune system reacts quickly to a pathogenic microbe to destroy it completely or to minimise the number of viruses or bacteria in the body.
The media also write about the likelihood of the accidental emergence of the ‘perfect’ disease, which would combine high measles contagion, a long asymptomatic period of HIV and antibiotic-resistant bacteria resistance to drugs, and low vulnerability to vaccines.
That said, the actual emergence of such a “super-disease” is almost impossible. Disease-exceptions may well be airborne and wipe out an appreciable proportion of the population, but they will later begin to act on natural selection among humans. By doing this, the virus will gradually cease to be dangerous to the population.
The antibiotic-resistant bacteria, often considered to be the most dangerous threat, also have serious limitations. Almost all of them are relatively safe for the human body, because they cannot find a loophole in human immunity. To be able to resist antibiotics, such bacteria change their parameters, become smaller in size and often show less ability to reproduce than competing species without pronounced antibiotic resistance.
The leaders among the causative agents of common diseases are the influenza virus and, even more frequently, the mutant HIV. According to the scientists, such viruses constantly change their outer shell composition so that they cannot be detected by immune cells. In doing so, the viruses begin to lose some of their strengths.
