[Global pertussis epidemiology and immunization strategies].

Pertussis remains to be a global public health problem, even in developed countries with full coverage of universal vaccination. This has been accompanied by a change of disease epidemiology, characterized by a significant increase in reported pertussis cases among adolescents and adults. Actually, reported cases of pertussis represent only a small part of the whole pertussis cases reservoir. In response to the changing epidemiology, several countries have implemented booster programs of universal adolescent vaccine. In this paper, the anther tries to review the changing epidemiology and reveal the causes of resurgence. By comparing pertussis immunization schedules in different countries, it will be helpful for reconsidering the vaccination strategic for pertussis in our country.
