For years the variations of the flu virus have been ahead of scientist rendering their medicine useless in eradicating the pandemic. Now the experts are looking into ways they can stay ahead of the virus by studying how it evolves, the strains with the deadliest effect and as well as vulnerabilities in the mutations. The RNA virus of the flu is unique because it allows replication by copying of the genetic code hence the presence of various strains. Another challenger is the migration of the flu as birds and animals carr…
