Highly infectious and unpredictable seasonal and avian influenza
viruses are emerging threats in Africa triggering WHO to guide
implementation of national influenza preparedness, surveillance and
control strategies to protect individuals and populations.
Influenza
viruses are deadly in their own right but they are also an important
cause of respiratory disease such as pneumonia, which is a major cause
of death in Africa, particularly among children.
In Africa, the
impact of influenza infection is not very well documented. However, the
information we do have shows that influenza viruses circulating in
animals (zoonotic influenza viruses, including avian influenza) pose the
greatest threat to human health.
This threat is due to people not
having immunity against these viruses. The concern is that influenza
viruses circulating in animals could develop traits in the future which
could permit them to be spread easily from person to person – possibly
triggering a new influenza pandemic.
With this, there is an urgent
need to better understand trends, risk factors and burdens of seasonal
and zoonotic influenza viruses. These significant gaps have sparked the
rapid expansion of influenza preparedness, surveillance and reporting to
better protect against both seasonal and zoonotic influenza viruses.
WHO/AFRO continues to support Ministries of Health, in collaboration
with Ministries of Agriculture and other governmental bodies, to protect
communities and further strengthen national influenza capacities in
line with the International Health Regulations (2005), Pandemic
Influenza Preparedness (PIP) Framework and within the context of the
Integrated Disease Surveillance and Response (IDSR) strategy.
To
enhance influenza surveillance in the African Region, a newly published
and disseminated standard operating procedure can be found at this
