Abstract


Background The three types of influenza viruses are A, B, and C. They belong to the Orthomyxoviridae family of single stranded RNA viruses.

Method Retrospective study was conducted on  7515 sample results data which were collected from January 2014 to December 2018 in the Department of Microbiology, Government Medical College, Kota

Results 16.58% samples were positive over the period of study. Prevalence in 2014 was 3.08% followed by the drastic change in the number of cases in 2015 with the prevalence of 18.57% with the similar trend in the successive years except in 2016 which might be due to change in humidity. Post-renascence the virus was able to infect even at higher relative humidity.

Discussion The dominant flu strain in India in 2017 was A/ Michigan/7/2009 (H1N1) pdm09 virus, replacing A/California/7/ 2009 (H1N1) pdm09 seen during 2016. The new strain is capable of infecting at relatively higher temperature.
