Question

Onde iniciaram as 5 maisores pandemias da história? Responda em inglês .​

Answer 1

Resposta:

1) Tuberculosis

Known for its high contagion capacity (it is transmitted from person to person, through the airways), tuberculosis has killed more than 1 billion. Its peak was between the years 1850 and 1950, with the intense urbanization and the lack of basic sanitation.

The disease started to be controlled after the identification of Koch's bacillus, which causes tuberculosis. It recently reappeared in poor countries and as an opportunistic disease in AIDS patients.

2) Black Death

Bulbonic plague is considered the biggest disaster caused by a disease. The outbreak occurred between the years 1333 and 1351 in Europe and Asia, and its degree of devastation was such that it became known as the Black Death.

It killed 50 million people, which meant a third of Europe's population at the time. Caused by the bacterium Yersina pestis, it is common in rodents like the mouse. It started to be controlled as hygiene and sanitation improved in the cities.

3) Smallpox

Between 1896 and 1980, smallpox, a disease that has plagued mankind for thousands of years, became an unprecedented epidemic. Transmitted through the respiratory tract, the Orthopoxvirus variolae virus killed around 300 million people in that period.

It was eradicated in 1980 after a mass vaccination campaign.

4) Spanish flu

The flu is known to be a constantly changing virus. In 1918, influenza had one of its most fatal developments, killing 20 million people in 1918 and 1919. Since most of its victims were in Spain, it ended up being baptized as Spanish flu.

To get an idea of ​​the degree of devastation of this flu, remember that the first World War, which happened around this time, killed just over 9 million.

5) AIDS

The HIV virus, which causes AIDS, has killed 22 million people since 1981, when it was identified in the United States. HIV, which continues without having a definitive cure, is transmitted through blood, sperm, vaginal discharge and breast milk.
