摘要: Since the first reported outbreak of dengue hemorrhagic fever in Pakistan, several mini outbreaks have erupted region. Dengue virus serotype 3 (DEN-3) was documented 2005 Karachi.

We conducted a detailed study three infection occurred years 2007, 2008 and 2009 by using molecular techniques such PCR nucleotide sequencing C-prM gene junction virus. Through analysis 114 serum samples collected over period (2007-2009), total 20 patients were found to be infected with In year four positive for one sample DEN-3. 2008, five had concurrent serotypes DEN-2 DEN-3 while only DEN-2. 2009, six only. Our showed dominant during (2007-2009). The other present Genotypes subtype IV III, respectively.
