Abstract: | Background Meningococcal disease is infrequently found in Taiwan, a country with 23 million people. Between 1996 and 2002, 17 to 81 clinical
cases of the disease were reported annually. Reported cases dramatically increased in 2001–2002. Our record shows that only
serogroup B and W135 meningococci have been isolated from patients with meningococcal disease until 2000. However, serogroup
A, C and Y meningococci were detected for the first time in 2001 and continued to cause disease through 2002. Most of serogroup
Y meningococcus infections localized in Central Taiwan in 2001, indicating that a small-scale outbreak of meningococcal disease
had occurred. The occurrence of a meningococcal disease outbreak and the emergence of new meningococcal strains are of public
health concern. |
