“…When studying the etiological structure of ARVI of non-influenza etiology in Kazakhstan between 2016 and 2019, the predominance of hRSv (15.25%) and hRv (4.34%) was established, hPiv and hAdv were detected much less frequently (about 1%). hMpv, hBov, and hCov were revealed in isolated cases [14,15]. The prevalence of hRSv and hRv in the pre-pandemic period was also recorded in different countries of Europe [41,42], Asia [35,37,39,43,44], and Africa [36,45].…”

“…The range of influenza virus epidemic strains is continually changing. In recent years, a rapid spread of influenza viruses of subtypes A/H1N1, A/ H3N2, and type B is being observed in Kazakhstan as well as throughout the world [14,15]. In addition, the extraordinary complexity of the epidemic situation is associated with the emergence of reassortant viruses.…”

swabs were collected from children under 17 years of age (60.75%). In 702 samples (9.85%) pathogens of respiratory infections of non-influenza etiology were detected, including adenovirus, bocavirus, coronavirus, metapneumovirus, paramyxovirus types I-IV, respiratory syncytial virus, and rhinovirus. At the same time, both before and during the COVID-19 pandemic, different influenza virus variants cocirculation (A/H1N1, A/H3N2, and type B) were discovered, with a predominance of viruses with the antigenic formula A/H1N1. The results of the study indicate the need for continuous monitoring of the viral pathogens spread, which will expand the existing knowledge of the viral etiology of respiratory diseases and highlight the importance of viruses in the respiratory infections occurrence.

“…The pandemic strain of influenza A/ H1N1pdm09 virus has become the dominant agent in the etiology of subsequent epidemic seasons. It has displaced the seasonal influenza A/H1N1 virus from active circulation in the human population [4] and is currently continuing to circulate along with A/H3N2 viruses and two type B lines [5]. In this regard, one of the major tasks in solving biosecurity issues is to control the distribution of the pandemic influenza A/ H1N1pdm09 virus, which has an enhanced virulence [6].…”

Influenza viruses are among the most prevalent infectious agents, leading to massive seasonal epidemics and pandemics with high mortality rates. The ability of influenza virus to antigenic variability determines the high population susceptibility, wide spread of infection, and short intervals between epidemics. In recent years, the co-circulation of influenza viruses that belong to A/H1N1pdm09 and A/ H3N2 subtypes and influenza type B virus has been observed. Here we summarize the data we explored to establish the features of the influenza virus circulation in the southern region of the Republic of Kazakhstan. To conduct virological and serological studies, 590 biosamples were collected from sick patients (419 swabs and 171 blood serums). Influenza type A virus RNA was found in 39 (9.31%) samples including that of A/H1N1pdm09 virus in 15 (3.58%), A/H3N2 virus in 23 (5.49%). It has also been noted that isolates A/Almaty/10/21 and A/Almaty/15/21 were profiled by the antigenic formula A/H3N2. The results of virological, serological, and molecular genetic studies confirm the simultaneous circulation of influenza A viruses (H1N1pdm09 and H3N2), and influenza type B virus. Some thoughts on the current scenario as well as implications for the future are presented as well.
