The team indeed confirmed that there was an on going meningitis outbreak. Three Cerebral spinal fluid (CSF) specimen cultures done by district lab grew some colonies that revealed gram negative diplococci. Sero-typing could not be done by the district laboratory technologist at that time due to lack of latex Kit.
