Abstract
Pertussis is an important respiratory tract bacterial infection. The infectious disease can still be seen in some
developing countries despite the vaccination is available. In Thailand, a tropical country in Indochina, this
disease is sporadically reported despite there is a universal diphtheria vaccination policy for all newborns.
Here, the authors summarize the data from recent reports on seroprevalence of pertussis among Thai patients
with chronic cough.
