In 1970 many experts thought that the fight against infectious diseases was over. In fact it was indicated far back then that the time to close the book on infectious disease is drawing near and that the war against pestilence was declared won, whereas national resources were to be channeled to.cancer and heart diseases.
This catapulted in a lukewarm approach to these which has led to less priority for communicable disease surveilance system, because of this, many developing countries could not maintain surveilance in their scheme in regards to health services and this has resulted in the retardation in medium of recognizing the level of negative impingement it has caused in the system of life.
During the last two decades, this opinion has been reversed and there is now a renewed appreciation and appearance of communicable diseases, like HIV/AIDS, hepatitis C,and dengue haemorrhagic fever and the resurgence of diseases long considered under control such as, malaria, chorela, tuberculosis, sleeping sickness etc have drawn considerable attention.
For instance tuberculosis is a very old disease. Literally, millions of people have suffered and died from TB. Malaria kills nearly one million children every year. In Africa, the average child is bitten by malaria carrying mosquitoes between 40 and 70 times a month. These mosquitoes are spreading to new areas, and anti-malaria drugs have become less effective.
Nowadays, the terrible epidermic of infectious diseases has surfaced outside the confines of the world that has inflicted pains and subsequent death to human population. Its has constantly rake havoc on the vast population. Clearly, significant battles have been won . But some public health victories have been confines to the richer countries of the world.
Treatable diseases still kill million of people, Maybe because of poor or a complete lack of funds. Already, in the developing countries especially in Africa and the Asia most people still do not have adequate health care and access to safe water, sanitation, etc. To cope with this couple with a large population size, it becomes difficult if not impossible for the authorities concern.
Also, our irresponsible behaviors has been in the forefront and a major factor causing the spread of these infectious diseases. This is a better instance in the issue of the AIDS infections. Because it spread across human race from one person to the other through body fluids. Within a few years this pandemic has spread across the globe, we did it to ourselves and so it has come to stay with us.
AIDS has emerged as a new global threat. In the last 20 years after its discovery, it has slaughtered over 60 million people, even with a serious warning from the health sector that it has not reach it peak. The rate of it onslaught is still on the high compared to statistics. The vast majority of people living with this pandemic are in their prime between 20 to 50 years of age, and are in their working lives.
Efforts to find a cure and or vaccine for its eradication has proved abortive. It is believed that only 4 percent out of the numerous sufferers in the developing countries have access to drug therapy. At present there is no cure for AIDS and Doctors fear that most people who are infected will eventually get the disease.
