Abstract A study was conducted during the period from August, 2015 to April, 2016 to survey the occurrence of viral diseases affecting chicken in and around Shillong, Meghalaya. A total of 370 dead and sick birds were collected from different organized and unorganized poultry farms in and around Shillong, Meghalaya. Of these, death in 109 cases (i.e. 29.46%) were diagnosed due to viral diseasesbased on clinical history, gross, histopathology and confirmation with detection of the viral genomes by polymerase chain reaction (PCR). Among the diseases, Newcastle disease (ND) was found in 15.14%, followed by infectious bursal disease (IBD) in 12.97% and fowl pox (FP) in 1.35%, respectively Age-wise analysis showed that the maximum number of cases in the age group of 4–6 weeks (33.03%), followed by 7–9 weeks (28.44%), 1012 weeks (17.43%), 1–3 weeks (14.68%) and above 12 weeks (6.42%) age groups of chicken. The present study suggests that some important viral diseases are occurring in chicken population in and around Shillong, Meghalaya with higher incidence affecting 4–6 weeks age groups.
