Infectious diseases. Statistics. Prevention
Anglų esė. Nowadays a number of people are concerned about diseases caused by micro organisms which are found in air, soil and water. Such diseases are called infectious, because they are caused by a biological agent such as bacteria, fungus, parasites, prions and viruses, which carry an infection. It is possible to become infected just by eating, kissing, drinking, touching, as well as breathing, insect bites, from animals and sexual contact. Infectious diseases can spread directly or indirectly, from plant or animal to person, or from person to person (medicinenet. Com). In this essay different types of infectious diseases, some statistics will be observed and some precautionary measures will be briefly discussed. Taking everything into consideration, it is obvious that infectious diseases play an important role in people’s life, since different micro organisms are everywhere. Infectious diseases can be caused by parasites, bacteria, fungus, prions and viruses. In addition, the number of people died due to infectious diseases is still very high. Finally, there are recommendations which can be helpful if people do not want to catch any of these diseases, and the most important are to wash hands frequently, not to share personal items and keep the kitchen clean. Here are mentioned only several diseases, however, there are many diseases which are related to infection. People, who are concerned about this matter, should think about some conferences and programmes to present these facts to people, since most of them, according to statistics, are not aware of it well.
Having observed different types of infectious diseases, it is useful to look at some statistics in order to form an impression about seriousness of such diseases. According to statistics infectious diseases caused ¼ of 56.1 million deaths in 2001, which is, obviously, a very high number (ps4h.org). Although the ‘World Health Organization’ provides the material on infectious diseases where it is seen that the percentage of people died due to these diseases has decreased from 1993 until 2002, the number of people died due to HIV/AIDS has increased from 0.7 million until 2.8 million (who.int). Other statistics found on the website of ‘World Health organization’ provide numbers which show that people, in 2004, die from infectious diseases in low-income countries mostly. Among diseases, in these countries, are found lower respiratory infections (2.94 million), HIV/AIDS (1.5 million), Tuberculosis (0.91 million), Malaria (0.86 million) (ibid).
Finally, some precautionary measures should be discussed, because it is beneficial to know what is necessary to do in order not to catch any of these diseases. There are ten basic recommendations for prevention the spread of infection and everyone is able to do it. Firstly, it is crucially important to wash hands frequently, especially before eating and after the restroom.
