Human Populations at High Risk

The population is very sensitive to the contraction of new diseases and the incidence of these diseases is at high risk. The most recent diseases in the population are H7N9 influenza virus and SARS. In spite of the risk, the outbreaks of H7N9, SARS, etc. are managed by epidemiological methods and other disease management methods. The occurrence of this disease is not unusual for the population as these diseases move to new areas around the world and suffer from outpatient disease that local people are resisting.

Thirty percent of the population is high blood pressure and has a risk of 90% of the rest of the life of each person. As a result, half of all deaths are due to major complications of hypertension, mainly due to stroke or heart attack. Medical scientists are fighting this life-threatening illness and they have had some success. This is the definition of several antihypertensive drugs and the definition of "normal" blood pressure levels to be maintained in order to reduce the risk of cardiovascular complications and death.

Most people in the population are low to medium risk. There are few people with high risk. Because very few people are in danger - many of them are causing heart attacks - but in general they account for only a small percentage of the total number of heart attacks in the population. An example of a preventive paradox is cardiovascular disease (CVD) risk. This is an estimate of human risk. Heart attack or stroke within a certain period. Most people are at low risk or medium risk, and few have very high risk. However, most CVD cases come from people with low or moderate risk. Although it is highly possible to develop CVD in high-risk groups, CVD cases in the population rarely derive from high-risk groups, as the proportion of high-risk groups is low.

Why is it important to screen women at high risk of breast cancer? High risk women may develop breast cancer 2 to 5 times more than general population. High risk women are younger than the general population. Breast cancer is a more risky young woman more aggressive, so it is important to discover it early.
