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.

Health experts at the Michigan Department of Health and Human Services (MDHHS) want people to know about the potential for swine at these events to carry influenza viruses which can make people sick, and to take some simple precautions.
Co-infection of different subtypes in canine may give an opportunity for the emergence of novel reassortant influenza viruses. Canine influenza virus (CIV) was first reported in 2004 from Florida racetrack Greyhounds and recognized as H3N8 subtype (Crawford et al., 2005).
Swine influenza is an infection caused by any one of several types of swine influenza viruses. Swine influenza virus (SIV) or swine-origin influenza virus (S-OIV) is any strain of the influenza family of viruses that is endemic in pigs.
Seasonal influenza viruses account for about 650,000 deaths per year, whereas pandemic strains such as the 1918 H1N1 virus have been linked to 50-100mn deaths worldwide.

In this study, we identified influenza viruses jumping from pigs into dogs," said study investigator Adolfo GarcE[degrees]a-Sastre, who is director of the Global Health and Emerging Pathogens Institute and principal investigator at the Icahn School of Medicine's Centre for Research on Influenza Pathogenesis (CRIP).
Ferrets and humans share similarities in lung physiology, cellular receptor distribution, and clinical signs of infection, making the ferret an attractive small mammalian model for laboratory study of influenza viruses (1).

At the same time, Agricultural Research Service (ARS) scientists are keeping a watchful eye on emerging animal influenza viruses. These viruses pose a public health concern, because they can potentially jump directly from animals to humans and cause serious disease.
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.
