We can control the spread of infectious disease by maintaining personal and good health and also practising hygiene habits.
  Maintaining good health The world health organisation (WHO) define good health as a state of physical, mental, and social well being of a person and not merely the absence of disease or infirmity. 
We can maintain good health by:
 * eating a balance diet 
* doing a regular exercise to keep the various part of the body in a good health condition. 
* resting the body mentally and physically through recreational activities and sleep(about 6 to 8 hours for adults, and more for growing. children); and doing work suited to our mental and physical abilities. 
 We can achieve social well-being through a well balance family and community life. Bad habits like excessive drinking of alcohol and smoking and drug addiction ruin the health of a person. So we must be careful not to acquire these habits. Good health help us to resist most pathogenic micro-organisms. 

These mechanism function effectively in a healthy person. The body's defence mechanism includes: - A healthy skin and mucous membrane which prevents the entry of pathogenic micro-organism into the body. - Substance in the tissue secretion such as tears,sweat,saliva and mucous secretion that kills or inhibits the growth of invading micro-organisms. - body's natural micro flora that prevent pathogens from colonizing the body. - the ability to produce antibodies, substances that can react with the invading pathogenic micro-organisms and prevent them or their toxins from harming the body.

  * note: malnutrition make the skin susceptible to injury, thus enabling micro-organisms to enter the body. Tobacco smoking and air pollutant weaken and injure the mucous membrane lining the respiratory tract, we should also take preventive measures to ensure good health by being vaccinated against disease like poliomyetlitis, diphtheria,tetanus,and tuberculosis. Again vaccine helps the body to make the relevant antibodies, so that when the actual disease causing micro-organism, get into the blood, the antibodies are already present or can be made quickly. This helps the body to get rid of the disease-causing micro-organisms rapidly. 

  The important personal hygiene habits include cleanliness and care of the body. The body is covered with an outer layer of the skin. The skin can only act as an effective barrier, preventing the entry of micro-organisms into the body if it is healthy and clean. We can maintain a healthy skin by taking sufficient vitamin A in our daily diet. In the tropics, e sweat a lot; sweat and oily secretion from the skin make gives off an unpleasant smell. Such a dirty skin becomes an ideal breeding ground for micro-organisms and ecto-parasite like fleas and mites. We can keep the skin clean by bathing with soap and Water, at least once a day. Scrubbing and washing the skin remove dust,dead skin call, oily secretions and micro-organisms. These contribute to our general well-being and give us a pleasant appearance, making us socially acceptable to the community. Special attention must be paid to the cleanliness and care of these parts of the body: 
 (A) hair and scalp
 (B) ears eyes and nose 
 (C) armpits and groins
 (D) hands and finger nail
 (E) feet and toes
 (F) teeth. 

Precautions taken to avoid being infected. 
 i. Keep yourself and your things clean
 ii. Wash your hand before eating and after using the toilet. 
 iii. Keep the food covered. 
 iv. Boil drinking water. 
 v. Keep worm and dirty wear shoes outside the house.
 vi. Do not use the personal thing of people with contagious diseases. 
 vii. Sleep under a mosquito net if there are mosquitoes in the area. 
 viii. Stay away from people with infectious disease.
 ix. Keep the environment clean.
 Following all this will make us have a better chance of living long and as well as being healthy.  Share with your love ones.
