Abstract
Since the first outbreak in the 19th century influenza virus has remained emergent owing to the huge pandemic potential. Only the pandemic of 1918 caused more deaths than any war in world history. Although two types of influenza- A (IAV) and B (IBV) cause epidemics annually, influenza A deserves more attention as its nature is much wilier. IAVs have a large animal reservoir and cause the infection manifestation not only in the human population but in poultry and domestic pigs as well. This many-sided characteristic of IAV along with the segmented genome gives rise to the antigenic drift and shift that allows evolving the new strains and new subtypes, respectively. As a result, the immune system of the body is unable to recognize them. Importantly, several highly pathogenic avian IAVs have already caused sporadic human infections with a high fatality rate (~60%). The current review discusses the promising strategy of using a potentially universal IAV mRNA vaccine based on conserved elements for humans, poultry, and pigs. This will better aid in averting the outbreaks in different susceptible species, thus, reduce the adverse impact on agriculture, and economics, and ultimately, prevent deadly pandemics in the human population.

Abstract
H7N9 avian influenza virus (AIV) caused human infections in 2013 in China.
Phylogenetic analyses indicate that H7N9 AIV is a novel reassortant strain with
pandemic potential. We conducted a systemic review regarding virus-induced
pathogenesis, vaccine development, and diagnosis of H7N9 AIV infection in
humans. We followed PRISMA guidelines and searched PubMed, Web of Science, and
Google Scholar to identify relevant articles published between January 2013 and
December 2018. Pathogenesis data indicated that H7N9 AIV belongs to low
pathogenic avian influenza, which is mostly asymptomatic in avian species;
however, H7N9 induces high mortality in humans. Sporadic human infections have
recently been reported, caused by highly pathogenic avian influenza viruses
detected in poultry. H7N9 AIVs resistant to adamantine and oseltamivir cause
severe human infection by rapidly inducing progressive acute community-acquired
pneumonia, multiorgan dysfunction, and cytokine dysregulation; however,
mechanisms via which the virus induces severe syndromes remain unclear. An H7N9
AIV vaccine is lacking; designs under evaluation include synthesized peptide,
baculovirus-insect system, and virus-like particle vaccines. Molecular diagnosis
of H7N9 AIVs is suggested over conventional assays, for biosafety reasons.
Several advanced or modified diagnostic assays are under investigation and
development. We summarized virus-induced pathogenesis, vaccine development, and
current diagnostic assays in H7N9 AIVs.
