District not reported



• Animal bites in Zarqa in 2007 accountedfor 8% of total bites in Jordan.

• Animal bites commonly occur in ruralregions, but in Zarqa about 60% of animal

bites were in urban regions possiblybecause 90% of Zarqa population lives inZarqa and Rusaifa cities.

• Most of bite victims were males, it seemsthat they stay more outside home ,and thatthey are more provocative to animals.



• Adolescents and young adults were moreaffected than children and elderly people.

• Sixty percent of bites occurred in spring andsummer (seasonality), probably because

people exist more outside home in thisperiod.

• Results of this study was consistent withother studies in that dogs are the main bitinganimals and that the lower limbs are the

mainly affected site.



Conclusion and

recommendations

• Animal bites are still a public health problem

in Jordan and demands extra efforts to becontrolled.

• The national campaign to get rid of straydogs should be thorough and continuous notto overlook stray dogs in urban regions.
