On July 26, 2017, the Taiwan Centers for Disease Control (Taiwan CDC) announced one cluster of 3 reported meningococcal meningitis cases at a military base. 2 were tested positive for Neisseria meningitides and one of them died. The test result of the other case is pending. All contacts have been evaluated by a physician and given the prophylaxis. All of them have been asked to monitor their own health. As of now, no new suspected cases have been reported and the outbreak has been brought under control.

 

On July 23, 2017, Taiwan CDC was notified of a suspected meningococcal meningitis case. The case was an active duty solider at a military base in northern Taiwan. On July 22, when he developed symptoms, he sought immediate medical attention. In the following morning, he died. On July 23, another hospital diagnosed the second suspected case of meningococcal meningitis at the same military base. To prevent further transmission, the local health authority conducted an expanded epidemiological investigation and implemented a number of prevention measures, which discovered the third suspected case that was reported to the health authority on July 24. Currently, the 2 cases are stable and being treated. A total of 191 contacts, including military servicemen, family members residing in the same households, and healthcare workers, have been identified. After the physician evaluation, 118 contacts were given the prophylaxis. The local health authority provided the contacts with relevant health education and asked them to monitor their own health till August 12.

 

According to the surveillance data compiled by Taiwan CDC, thus far this year, a total of 8 meningococcal meningitis cases, including 1 death, have been confirmed.
 

Meningococcal meningitis is an acute infectious disease caused by meningococcus. The disease is transmitted from person-to-person through droplets of respiratory or throat secretions from carriers. The incubation period ranges from 2 to 10 days. The symptoms include fever, severe headache, nausea, vomiting, neck stiffness, hemorrhagic rash, pink spots, confusion or other mental changes, coma, and seizure. When necessary, antibiotics are prescribed as the treatment.


To ward off meningococcal meningitis, wash hands with soap and water frequently, maintain good indoor ventilation, avoid staying in poorly ventilated rooms for long hours, and seek prompt medical attention when suspected symptoms developed. Physicians are advised to be vigilant for suspected cases and prescribe antibiotics when appropriate. Travelers planning to visit areas affected by meningococcal meningitis are advised to visit the outpatient travel clinic at contracted hospitals in the nation to evaluate the need of meningococcal meningitis vaccination prior to their trip. The public is urged to seek timely medical assistance when suspected symptoms develop and inform the doctor of any recent travel history to facilitate prompt diagnosis and case reporting. For more information, please visit the Taiwan CDC website at http://www.cdc.gov.tw or call the toll-free Communicable Disease Reporting and Consultation Hotline, 1922 (or 0800-001922).
