Let see factual aspect?
We are not still working on "How did dengue spread in Pakistan?"
Might possible, we may be able to plan for future.
Dengue outbreak started from Karachi where vector was controlled successfully as natural slope topography, water doesnt stay, or make ponds. Except, if sewerage channels are not blocked.
Karachi being the city of immigrants for earning livelihood, people returned home on EIDs and it facilitated to develop inoculum at smaller level. Due to Karachi unrest and other issues, industry moved to Lahore and other cities and so the laborers too, which helped to develop the inoculum in Lahore also.
But still there is a mystery? How does the Aedes boost in short time in Lahore? Its not gradual? You may disagree? But I think reasons is negligence and not focusing in unaffected areas?
