Scientists have identified the typical signs of infection.
Researchers from the school of public health at Johns Hopkins University published a report according to which the next pandemic, which may cause the death of thousands of people worldwide, is caused by a viral infection, transmitted by airborne droplets.
According to researchers, the threat from such agents of deadly diseases like the Ebola virus or zika virus, are greatly exaggerated. Much more likely that the pandemic will cause RNA-containing virus genetic material are less stable than DNA, nucleic acids. This allows infectious agents to mutate rapidly, avoiding the immune system are infected, making it potentially lethal.
Scientists have identified the typical signs of this infection, analyzing the possible factors contributing to the global epidemic. So, the virus must be able to infect other people before the carrier will not manifest the first symptoms, and it must be unfamiliar to the immune systems of the majority owners. In addition, for infection should be characterized by relatively low (compared to haemorrhagic fevers) level of lethality. Such properties are the causative agents of flu, colds and SARS.
One of the deadliest pandemics, the “Spanish flu” was caused by the flu virus. They contracted 29.5 percent of the world’s population, and the mortality rate was 10-20 percent. The Ebola virus mortality rate is up to 90 percent.
