Priority Class-A Diseases
Class A diseases are reported within 24 hours in order to produce a rapid alert and initiate necessary actions to confirm or not a potential outbreak.
In the reporting period, one case of viral meningitis was reported from Maghazi HC. The patient was a 2 months old boy. A case of bacterial meningitis of a 12 year old boy was reported from Bureij HC. All needed public health measures including isolation and health education were taken.
What is new is the appearance of cases of influenza A H1N1in Gaza starting from 6 December 2009. 153 cases of influenza A H1N1 have been confirmed in the Gaza Strip as of 18 December 2009. 11 people have died due to influenza A H1N1 but all had additional risk factors. The number of confirmed cases presented in this report surely underestimates the actual number of people affected by influenza A H1N1.
During the reporting period, only one case of mumps was reported from Nusierat HC. She is a 5 years girl who was immunized at 15 months. All needed management and public health measures were taken (isolation, health education was provided to contacts).
The majority of non vaccine preventable Class B diseases (54%), were attributed to watery diarrhea among children under three years of age. Other leading causes of morbidity were watery diarrhea in the refugee population above three years (34%) followed by acute bloody diarrhea (11%). Cases of acute hepatitis (acquired through syndromic surveillance) accounted for 1% of the proportional morbidity.
