WHY DO WE FALL ILL PART 2
HOW TO PREVENT SPREAD OF DISEASES Spread of diseases from an infected host to a healthy host can be prevented to a great extent if are aware of certain points and follow certain hygienic practices. We can prevent airborne diseases by avoiding exposure to overcrowded areas, using masks to cover nose and mouth while going out. We can prevent water borne diseases by making water free from germs by boiling them, using disinfectants like chlorine to kill the microbes in water, using proper water filtration equipments available in markets.
o We can prevent vector borne diseases by preventing the growth of vectors in our surroundings. This can be done by keeping our surrounding clean, cleaning stagnant water (in potholes, coolers, pots, tyres or beakers), covering the drains and garbage bins, practicing proper garbage disposal habits, etc. Avoid using public toilets. e Avoid drinking water and food from unhygienic and dirty places. e Always wash hands thoroughly before eating food
Avoid using others' personal belongings. . Maintain proper hygienic habits. Avoid using the same syringe used to inject previous patients, blades or razors used to shave previous customers in salon.
HOW TO TREAT DISEASES e The two ways to treat diseases are to reduce the effects of diseases and to inhibit the growth or kill the disease causing microbes. In order to reduce the effects of the disease take medicines to reduce pain and fever to some extent accompanied with adequate rest to conserve energy Each kind of disease causing microbes like virus, bacteria, fungi, protozoa have their separate and unique biochemical life processes. The life processes of one organism are not shared by other organism. The bacterial infections can be cured by using antibiotics.
Antibiotics are the medicines that inhibits the growth or kills the bacteria causing microbes by blocking the pathway for bacterial synthesis but does not affect its own pathway. o The antibiotics block the biochemical processes used by bacteria to build cell wall that protects them. Consequently, the growing bacteria cannot make cell walls and dies at the end. But viruses on the other hand have very less biochemical life processes of their own and hence uses our mechanisms for their life processes that results in lesser number of virus specific targets to hit by the antibiotics. Therefore, antibiotics cannot cure viral diseases or infections. But still there are many anti-viral drugs available in the market. Specialised cells called immune cells in human body fights off disease causing microbes and kills them everytime such microbes enter the body.
If the specialised cells kills the microbes then we don't fall sick. healthy. chances of suffering from it again because when a body suffers from Availablity of proper, sufficient and nutritious food is necessary to stay o If a body suffers from a particular disease once then there are lesser an infectious disease for the first time it fights against it and kills it. The the immune cells win the fight then we are disease free or else we fall sick. The cells remembers how to respond to that specific disease due to which when the body encounters from the same disease next time, it responds to it with increased vigour. This helps to eliminate the infection at a greater speed.
VACCINATION Vaccine is a biological preparation that resembles a disease causing microbe. Vaccination is the process in which vaccine is given to improve the immunity of the body against a specific disease. Vaccination are available for diseases like tetanus, diphtheria, whooping cough, measles, polio, chicken pox, etc. o The microbe injected into the body through vaccination is a dead or a weak microbe and hence does not affect the body. Therefore the immune system is able to manage. But at the same time the immune system also recognizes the microbe and the ways to fight it back. * When the same microbe comes to affect the body next time then the immune system recognizes it and fights back thereby prevents us from getting sick.
