title: Seroprevalence of pediatric malaria in quetta, balochistan, pakistan.
abstract: BACKGROUND
  Malaria is one of the most devastating protozoal diseases in under developing countries like Pakistan where health facilities are scarce. It is the second most frequently reported disease with 4.5 million suspected cases in Pakistan. The current study was designed to determine the incidence of pediatric malaria in Quetta, Balochistan.
  
  
  METHODS
  The study was conducted at Children Hospital Quetta (CHQ) during July 2011march 2012. Blood samples were collected from 3418 clinically suspected and were evaluated using thin and thick blood films stained with Giemsa stain.
  
  
  RESULTS
  Out of 3418 total of 230 (6.72%) children were found positive for any of the malarial parasitic infestation. Plasmodium vivax was observed to be more common 54.34% (n= 125/230) than P. falciparum 44.78% (n = 103/230). Male children were 65.21% (150/230) i.e. two times more commonly affected than female 34.78% (80/230) children. The prevalence among age groups was 7.41% (n = 89/1200) in preschool-aged children aged 1-5 years, 7.11% (n = 75/1054) in school-aged children aged 6-10 years while 6.78% (n = 46/678) in 11-15 years-old children, and 6.66% (n = 20/300) in >15 year-olds children. Peak prevalence was noted in summer and mild in winter. Mixed infection of (0.86%: 2/230) P. vivax and P. falciparum was also observed in two cases although no case of P. malariae or P. ovale infection was seen during entire study.
  
  
  CONCLUSIONS
  The results reflect the higher prevalence of malaria in Quetta, Pakistan that poses a significant health threat and requires urgent attention of high-ups to launch programme to control the disease in the area.
