The present study was conducted to estimate the prevalence rate and to identify risk factors of Cytomegalovirus, Rubella and Toxoplasma gondii among internally displaced women of District North Waziristan, Pakistan with home obstetric history. A total of 387 blood samples were collected from internally displaced infected women with the help of a comprehensive filled data form. To determine levels of Cytomegalovirus, Rubella and Toxoplasma gondii Infection, all blood samples were qualitative and quantitative analyzed using Immune chromatographic and Chemiluminescence Microparticle Immunoassay (CMIA) technique. Among 387 blood samples, the total numbers of reactive samples observed were 341 (88.11%) and non-reactive samples were 46 (11.88%). Of 341 (88.11%) reactive samples, the highest ratio 168 (49.26%) was reported for the co-infection of Cytomegalovirus and Rubella, followed by 76 (22.28%) for Cytomegalovirus, Rubella and Toxoplasma gondii combined. In reactive samples, the highest ratio of IgG was noted in order of CMV 22 (64.70%), Rubella 21 (67.74%) and Toxoplasma gondii 16 (72.72%), followed by IgG+IgM and IgM only. Regarding age-wise distribution, the highest ratio 144 (90.56%) of total reactive samples of Cytomegalovirus, Rubella and Toxoplasma gondii was reported in the 25-32 years old group of individuals. Similarly, the highest ratio 53 (48.18%) and 60 (41.66%) of co-infection among reactive samples for Cytomegalovirus, and Rubella was observed in 18-24 and 25-32 years old group. Further, the highest ratio of 100 (40.32%) of risk factors was observed in infected patients who were exposed to a poor hygienic environment and 57 (44.18%) of infected patients had complications of Severe UTI followed by others. Hence, it was revealed that Cytomegalovirus, Rubella and Toxoplasma gondii infection was most prevalent in internally displaced women of District North Waziristan, Pakistan. Therefore, an urgent base prophylactic approaches should need to be addressed to reduce the risk of the spread of disease in this locality.
