Pandemics (mass epidemics)

Pandemic is an epidemic that is massive in nature. That is, an epidemic that can spread across territories of many can hit entire continents.countries that

The most famous pandemics

– Flu is an acute infectious disease, which is the most common and most known in the world. Even in our time, it was not possible to win the pandemic. And even though the mortality of the disease is very small, the influenza still carries several hundred thousand human lives each year (no more than half a million).

– Tuberculosis is another dangerous pandemic of our time. About 8 million people are affected each year, and a quarter of them die.

– Plague. For the first time about this disease became known more than thousand years ago. From time to time, the plague passed through the continents, taking many human lives, because the mortality rate was 95-98%. At the moment, the epidemic has almost been stopped. Mortality is not more than 10%, with appropriate treatment.

– Smallpox – a pandemic raging in the 19-20 centuries. At the beginning of the 20th century it was taken under control, thanks to mass vaccinations. And despite this, in the last century, about half a billion lives have been spent.

– Malaria is an infection that is widespread in countries with a warm climate (tropics and subtropics, predominantly). Each year the disease is subjected to up to half a billion people, and several millions die from them. True, mortality increases with each passing year, as drugs are becoming less effective.

– HIV infection. According to statistics, on our planet, 1 in 150 people is a vector of HIV infection. But since the disease has a long incubation period (up to 20 years), during which it does not deliver problems, many people are not aware of the presence of the disease. The final stage of the infection (AIDS) leads to death, because the medicine does not formally exist from it.

– Tif is far from the most dangerous of pandemics. But the outbreaks of the occurrence of typhus are also mentioned for 400 years BC. And the victim of an infectious disease succeeded only in the 20th century.

– Cholera The epidemic took a mass character only in the 19th century, although it was known before and before the cholera. It is the cause of the death of millions of people.

– Leprosy (leprosy) – a disease that results in lesions of the skin and tissues of the body. What, in turn, is the cause of disability and ugliness. It is for this reason that the disease has such a name. There is no healing, however, it is quite successful to suppress the emergence of new outbreaks of the disease. So, over the past 20 years, the number of illnesses has fallen from several million to several hundred thousand people.
The threat of epidemics

To date, medicine is capable of dealing with emerging pandemics. Let not always it turns out effectively, and it is not always possible to avoid high mortality, but at least somehow it is possible to struggle anyway. However, viruses and bacteria are constantly evolving, because of which the struggle with them is becoming more complicated and complicated. As a result, it can lead to a pandemic, which can not be stopped anymore. Hope this will not happen.
