It is a viral illness caused by polio virus that can lead to paralysis, limb deformities, breathing problems or even death. Polio virus resides only in humans and passes on to the environment in the faeces of someone who is infected. Polio is still endemic in three countries, i.e., Pakistan, Nigeria and Afghanistan and is eradicated from the rest of the world. Pakistan is considered as the exporter of Wild Polio Virus (WPV) with highest number of polio outbreaks among endemic countries. With the start of World Polio Eradication Initiative in 1988, the number of polio cases has been reduced up to 99% worldwide until now. In 2015, Pakistan has shown a decrease of 70–75% in number of polio cases as compare to last year which is the result of good government's initiatives. Militant organizations such as Tehreek-e-Taliban Pakistan, Al-Qaeda and Boko haram movement of northern Nigeria are a major hurdle in the eradication of polio from these countries. The misconception of people about polio vaccine, insecurity within the country and poor health system are the reasons of failure of polio eradication campaigns in these regions. Awareness campaigns about polio for locals and development of proper health system will help in the eradication of polio. Once polio is eradicated, about 40-50 billion dollars can be saved globally. With the strong commitment, seriousness and good initiatives, polio will be eradicated from Pakistan within two years more likely.

The causative agents are ticks which show diversity in their strains and thus it is difficult to make vaccine, however some strains are conserved which is the positive point in vaccines development. From 2012 to 2015, a total of 161 cases were confirmed for Crimean-Congo hemorrhagic fever virus in Pakistan. And from 2012 to July 2014, 45 deaths were reported in the country. It is spreading sporadically in Pakistan. Mapping of endemic areas and cross-border veterinary surveillance should be developed in high risk areas and workshops should be arranged to increase public awareness about the disease. Control measures must be taken to avoid spreading of the disease to new areas.

Hepatitis C is a major cause of liver disease, while AIDS results in progressive failure of the immune system that allows life threatening opportunistic infections and cancers to thrive respectively. The objective of this study was to analyze the prevalence of HCV, HIV and HCV/HIV co-infection among different groups of apparently healthy people of Peshawar cantonment and to know the risk factors. The study was conducted at Pathology department, Khyber Teaching Hospital Peshawar Cantonment from February 2013 to June 2013. A total of 400 people from general population were screened for HCV and HIV by ELISA method. The overall prevalence of HCV shows that out of 400 samples for HCV, 340 subjects were found negative and 60 were positive for HCV. Age of the subjects was 19-60 years. 40 samples were screened for each group and out of 40 samples each 16(40%) shopkeepers, 10(25%) barbers, 10(25%) drug users, 8(20%) sweepers, 8(20%) food workers, 2(5%) out of 40 each among scrap merchants, mechanics, government employs and health care workers were positive for HCV. However, all the samples from students were HCV negative. 28% HCV positive cases were below the age of 40 (<40 years), while 51% of the HCV positive cases were above the age of 40 (>40 years). 95% of the HCV positive individuals were uneducated and 60% of HCV positive individuals were married. The total prevalence of HCV in Peshawar cantonment was 15% while the prevalence of HIV and HCV/HIV co-infection was 0 %. The majority of study groups were uneducated and belonged to low socioeconomic status. The risk factors include commercial sex and non-marital sex, sharing blades and shaving kits, exposure to infected blood or infected needles, using unsterile equipment’s, injection drug use and unawareness. It is concluded that chronic hepatitis C is common in asymptomatic healthy population and they are the possible candidates for chronic liver disease and potential sources of spread of infection, while HIV or HCV/HIV co-infection is not prevalent in the studied region.
