influenza viruses

in·flu·en·za vi·rus·es

viruses of the family Orthomyxoviridae that cause influenza and influenzalike infections of humans and other animals. These viruses contain single-stranded RNA that is segmented, accounting in part, for their epidemic spread. Viruses included are influenza virus types A and B of the genus Influenzavirus, causing, respectively, influenza A and B, and Influenzavirus C, which belongs to a separate genus and causes influenza C.

The majority of the influenza viruses collected and received from the United States and other countries during that time have been characterized genetically or antigenically as being similar to the 2017 Southern Hemisphere and 2017-18 Northern Hemisphere cell-grown vaccine reference viruses; however, a smaller proportion of the circulating A(H3N2) viruses showed similarity to the egg-grown A(H3N2) vaccine reference virus which represents the A(H3N2) viruses used for the majority of vaccine production in the United States.

In the current study, using virus histochemical analysis, the investigators looked at the pattern of attachment of two genetically engineered emerging H7 viruses (containing the hemagglutinin (HA) of either influenza virus A/Shanghai/1/13 or A/Anhui/1/13) to fixed human respiratory tract tissues and compared the findings to attachment patterns seen with human influenza viruses with high transmissibility but low virulence (seasonal H3N2 and pandemic H1N1) and highly pathogenic avian influenza (HPAI) viruses with low transmissibility and high virulence (H5N1 and H7N7).
Also, a universal vaccine could conceivably protect against highly pathogenic pandemic influenza viruses, such as the swine flu H3N2 or the even more lethal avian H7N9 influenza virus.
