Scientists
are warning the world that while we are immersed in our individual and
collective efforts to tackle the furious spread of the Covid-19
coronavirus, there exists concurrently an explosion in another deadly
disease that could pose a threat to public health globally.
The
H5N8, a subtype of highly pathogenic avian influenza virus (HPAIV), has
been discovered many years ago, but during 2020 a series of emerging and
ongoing H5N8 outbreaks in avian populations across dozens of countries
have led to the death and slaughter of millions of birds worldwide.
The
affected geographic regions have been expanding continuously, and at
least 46 countries have reported highly pathogenic H5N8 AIV outbreaks
already.
If leaders ignore this worrisome trend, and do not
monitor and contain the spread of this new H5N8 avian flu virus, the
World may have a double health pandemic at hand.
While the most vulnerable animals to H5N8 virus are birds, humans have also been infected by this virus recently.
An
outbreak of the avian flu in Russia in December 2020 jumped to poultry
workers in a farm in southern Russia – representing the first time the
H5N8 virus has been found in humans.
While that was a first for
H5N8, it certainly wasn't a first for clades and subclades related to
H5N8, nor for avian flu viruses in general.
There is now a total
of 862 confirmed cases of human infection with the Avian flu, including
455 deaths. These cases are from 17 countries, spreading across Europe,
Eurasia, Middle-East, Africa, America, Asia and elsewhere.
Point to note, 76% of the H5N8 cases are from Egypt and Indonesia.
In most of the recent outbreaks, a clade of H5N8 called 2.3.4 has become the dominant infector worldwide.
This shows that the H5N8 virus has a propensity for rapid global spread in migratory birds.
At
the same time, this virus also display evidence of constant evolution,
genetically re-assorting themselves with parts of other Avian viruses.
Though
the Covid-19 Pandemic has seen a big reduction in the Type A and Type B
common flu, however, in over the same time frame, a number of highly
pathogenic H5Ny AIVs, including H5N1, H5N2, H5N5, and H5N8 subtypes,
have been spreading across the whole world.
These viruses show
particular cell-binding adaptations that could pose greater risks for
human transmission, including potentially human-to-human
transmissibility.
Therefore, it is imperative that we must be now
take responsibility, instead of taking umbrage, to keep a very close
watch on this H5N8 Variant and ensure that they do not spread among our
community.
