Role of microbes in creating health hazards

Health Hazards Caused by Microbes

Bacteria may get entrance in many different processes. Dirty hands may act as suitable carrier. Bacteria can enter into the mouth through dirty hand. Bacterial spores may also be transported with the clothes that we use. Bacterial spores may travel from one place to another with the dust in the air. 

We used to shake hands and exchange salam when we meet each other. Bacteria may easily get transferred through shaking hands. Germs disperses easily through stale and rotten foods. These microbes sometimes are waterborne and
get dispersed dangerously with water. In the past due to this type of germs a
huge number of villagers perished. Cholera and Typhoid are bacterial diseases.
Once spread of diseases caused by virus, bacteria and Entamoeba was very high. Now we can say that it was caused due to shortage of safe water. Defecation
and urination hither and thither create risk in public health. Animals feeding on
these fecal matters disperse the germs from one place to another. Besides, the
rain water and tidal water also spread the germs to distant places. Like fecal
matters, there is a chance that saliva may spread the germs. Spitting here and
there may spread virus and bacteria and create threat to public health. Returning
from the latrine if hands are not washed properly with soap or ash, there is a
chance of entering the germ into the mouth and ultimately settles in the stomach.

In some village areas there is no sanitary latrine and the people use fields or unhygienic
latrines for defecation. Entamoeba infested fecal matters get mixed with the soil.
Handling that soil contaminates hands. Vegetables grown in those soils are also
contaminated. Vegetables sometimes contaminated with Entamoeba germs. After normal
cooking Entamoeba germs are still alive. Entamoeba is transmitted in these ways.
When infected with virus, sometimes it is cured normally within 2/4 days without any
medical help. But some diseases need long term treatment. Virus particles of cough and
cold spread through coughing and sneezing. Mosaic diseases of plants are transmitted
with simple contact. AIDS (Acquired Immune Deficiency Syndrome) disease is still not
curable. This disease is transmitted when blood from infected person is taken, taking
drugs by those who are addicted, using same needle while taking injectable medicines and
involvement in immoral trafficking. Mumps, Pox, Measles etc. are very painful diseases.
These viral diseases are transmitted through air and get into the respiratory tract.
