Bad cold is generally viral in origin. Antibiotic have no role in curing it . Patient's body takes about 7 days to produce interferon (an antiviral substance) to kill the virus of cold.

A number of chronic diseases are metabolic disorders which appear after middle age, e.g., diabetes, hypertension. Some require a long exposure to the pathogen, e.g., leprosy. In all cases chronic diseases are slow developing diseases. Therefore, they occur in few cases as compared to acute diseases.

Diseases which are transmitted from one individual to another directly are called infectious diseases. Such diseases are acquired, not inherited. If we prevent the entry of the disease-causing pathogens into our body, then we can prevent the disease from occurring instead of curing the disease afterRead more

Dengue is an infectious disease transmitted by the mosquitoes of genus Aedes. So, wearing socks and full sleeves will prevent them from biting. Thus, it is a preventive measure against dengue.

A person may be carrier of some disease. Such a person may take that particular disease to a foreign country. Therefore, all visitors to a foreign country are vaccinated against the disease which is not prevalent in that country

It is difficult to develop vaccines against the diseases caused by viruses. Viruses are very specific to hosts. They live and multiply only in the living cells. They cannot be cultured on artificial medium. It is because of these factors that vaccines are difficult to be prepared in such cases. HoweRead more

However, living cells of human’s body which are exposed to action of a virus, secrete a heat stable basic antiviral glycoprotein of low molecular weight, called interferon.
