Health Problems


Due to increase in the amount of annual rainfall, more contamination of water in the third world countries has led to mosquito-prone diseases such as malaria, sleeping sickness, etc. For examples, countries like Africa and India.

Some of the known infections have increased its severity in spreading the disease vastly among animals and humans are shown in the table below.

As we all studies in our biology classes, the bacterial diseases can be cured by antibiotics courses. Until a certain stage of the disease, depending on which disease it is. But viral disease can’t be cured even with antibiotics. This explains that the viral diseases are much more dangerous and harmful as compared to bacterial diseases.

2.
Cholera

7.
Tuberculosis
Bacterial
Infection that is caused in lungs (major part of the body) and other organs too.
8.
Yellow Fever
Viral
Mosquitoes carry this disease. With change in temperature the disease gets spread to other new regions.

Asthma is another major health-concerned issue that is caused by the change in the global atmosphere. High amount of greenhouse gases are emitted out from more industries and leading to air-pollution. This pollution in the air is leading to allergies and difficulties in breathing; asthma.
