It is said that diseases have killed or disabled more people then all the wars ever fought. Each year, tens of millions of people die from different kinds of diseases. In the United States alone, diseases kill nearly 2 million people each year and leave many people permanently disabled. Apparently it seems that God is solely responsible for all kinds of diseases as He has created the viruses, bacteria which cause many different kinds of diseases. But this is not tr ue.
Medical experts say that almost all diseases are caused by ignoring the standard laws of nature. i.e., our life-style, habits, living conditions and physical environment nur ture diseases. Let's take malaria, the most common disease of the third world countries. Malaria is caused by protozoan called plasmodia and is transmitted by the bite of the female anopheles mosquito. It is true that Allah Subhanahu taala has created the mosquito and plasmodia which infect us with malaria.
But Allah has also instructed mosquitoes to live in dir ty water and filthy environment. thus, by creating a dir ty environment, we invite mosquitoes, houseflies, rats, and other germs carriers in our home to deliver diseases. Similarly AIDS, the most dangerous and incurable disease, which has killed millions of peoples, is a disease sponsored by criminals. The cause of AIDS is HIV virus, undoubtedly created by Allah, but who transfer it into the human body ?
Allah or the patient himself /herself. At least in this particular disease doctors have honestly acknowledged that the only source of this disease is the patient himself / herself as he or she is the one who has acquired it. That is why they have named it Acquired Immune Deficiency Syndrome. Even those innocent people who get this disease from blood transfusion or blades are due to the human negligence.
Thus in most of the cases, the sufferings due to the chronic disease that makes the life miserable, are the result of our own deeds. Black Death. As mentioned above, not always but in most of the cases, the cause of the disease is one's bad deed or negligence of Divine orders. Sometimes the whole nation is punished by epidemics.
Scientists say they don't yet know, how all of sudden a particular epidemic disease grows and spreads widely killing millions of people and then goes away itself without any human efforts. For example, outbreaks of plague have been repor ted in different periods of history that have killed hundreds of millions of people.
