On September 27, 2011 Pakistan Medical Association (PMA) have asked the security agencies to probe into the deliberate spread of Dengue virus into Pakistan (Pakistan Observer, 2011). The demand of doctors has spread across the globe immediately and in Pakistan it has been creating massive anti-American sentiments because the public perception that dengue is being used as an agent of Biological warfare to kill or threaten the Nation besides Drone attacks and other deadly covert operations. By the end of September 2011, about 12,000 people were affected of the disease. Due to the sudden and rapid spread of the disease, “In less than a month, 126 people have died and more than 12,000 have been diagnosed with the virus, which has spread rapidly among both rich and poor in Pakistan's cultural capital Lahore” (Gilani, 2011) while as of today, total number of dengue patients is 16,288 with 201 deaths so far in Punjab province of Pakistan.
In 1967, Science Magazine reported that at the US government center in Fort Detrick, Maryland, dengue fever was among those diseases that are at least the object of considerable research and that appears to be among those regarded as potential BW (biological warfare) agents (Blum, 2003, p. 189). Before discussing the reasons for dengue as choice for CIA as biological warfare agent, we see the intellectual opinion and potential of dengue as being a biological warfare agent.
