Preventive healthcare, or prophylaxis, consists of measures taken for disease prevention.Disease and disability are affected by environmental factors, genetic predisposition, disease agents, and lifestyle choices and are dynamic processes which begin before individuals realize they are affected. Disease prevention relies on anticipatory actions that can be categorized as primal,primary, secondary, and tertiary prevention. Ancient Diseases are the diseases, which will provide information about characterization, diagnosis and treatment of various infectious diseases. These ancient diseases are acting as source of clinical and microscopic findings of a particular disease, by providing details like date and time of its emergence along with symptoms. Disease prevention can be achieved by eliminating causative agents or by gaining more resistance towards that particular disease. Remedies are nothing but the precautions or prevention methods which have taken to stop something bad from happening or arising. The impact factor of journal provides quantitative assessment tool for grading, evaluating, sorting and comparing journals of similar kind. It reflects the average number of citations to recent articles published in science and social science journals in a particular year or period, and is frequently used as a proxy for the relative importance of a journal within its field. It is first devised by Eugene Garfield, the founder of the Institute for Scientific Information. The impact factor of a journal is evaluated by dividing the number of current year citations to the source items published in that journal during the previous two years. Disease is an abnormal condition of an organism that will exhibit specific symptoms and affects regular metabolism.
