Cholera is also a kind of infectious disease, but in recent years in the society is relatively rare, many countries will not appear this disease, but this disease in some poor countries will still occur, this is why? We'll take a look at it today.
We first need to know that cholera is a disease that is mainly transmitted through water, seafood, fruits and so on, and this is the reason why patients get sick. So why the poor countries are always outbreaks of these diseases, or with the above sources of infection related.
The first reason is the water source, the economic condition of the country is also due to the lack of clean and hygienic water source in these countries. These countries do not have as much disinfected water as we do to drink, so the Dutch unclean water will naturally get sick, the water that the sick people drink also contains a lot of bacteria, some of this water if you drink to the body inside the natural will be sick, many serious patients will appear dehydration, diarrhea.
The second thing is that this poor country does not have a good sewage system. Our country has a very good sewage system, some industrial and domestic wastewater, sewage after treatment will not threaten human life and health safety, but some of these countries may not be due to economic wealth and other reasons, there is no way to implement the sewage treatment, some of the industrial wastewater so that the people drink it will naturally be sick.
The third reason is that people in these countries have poorer health and lower resistance. They can get sick easily because they don't get enough nutrients and their bodies are not as strong as they should be.
The above is my own opinion, if you still have other ideas, welcome to communicate with me to explore.
