This article will talk about some of the things through which you can tell if the person in question is suffering from some kind of illness or not. The disease or virus in human system causes pain, suffering, dysfunction and even deaths in its extreme case. Some of the diseases are transferable and are known as contagious disease. This means that if the diseased comes in contact with healthy person, then there is a possibility that the latter might come in contact with the virus too.
Some of the diseases are transferred into the body through some medium from outside. For example due to infections or stale food and water, germs transmitted through air from another person , coming in direct contact with the person who is already suffering from some disease and even from the objects which were used by an ill person. Sometimes a diseased person might not even know himself of the fact that he is going through an illness. Since the beginning of human race, every doctor, priest and saint have been trying to find cure of illnesses and they have successful to some extent. But there are still some viruses whose cure has not been found.

Due to huge number of viruses and diseases, it is sometimes difficult for even doctors to find the type of virus that is present in the patient’s body. If the person in question is acting differently and in a strange manner then it is likely that he is ill. This is because of the fact that when a person is not healthy then he or she would not be able to perform at optimal level. Besides this, he or she might not pay full attention to the work at hand. A person with a disease might be lazy too because much of the body energy is being utilized to fight the infection. Apart from this some of the symptoms of common disease like flu and cough can be easily seen in any person. If one is diseased, it normally causes the temperature of the body to rise and this can be checked with the help of a thermometer. But for complicated viruses, medical tests should be taken.
