Of the 9 suspected sera from pertussis patients in Beijing, 7 were serum-specific anti-PT and anti-FHA antibodies (both anti-PT and anti-FHA antibodies or were higher than those of whooping cough) Antibody positive index of 30Eu / ml. The results showed that there was still pertussis disease infection in the uninfected or immunocompromised as well as in preschool children and immunized adolescents.
