Overview
There is no evidence of an actual
or imminent disaster threatening
the jurisdiction.
Overview
Information exists suggesting
that a serious threat may be
developing and could eventually
impact the jurisdiction.
Triggers
Evidence of influenza-like
illnesses (ILI) in multiple
locations on one continent other
than North America (WHO
Pandemic Phase 4/ Federal Stage
2) suggestive of human-tohuman transmission.
or
Evidence of an outbreak in
multiple locations in North
America suggestive of humanto-human transmission.
or
A particularly serious outbreak
in contiguous states. Human-tohuman transmission is possible.
or
Morbidity/mortality is
considerable.
Overview
The possibility of a
pandemic or epidemic
directly impacting the
jurisdiction is more real
than theoretical.
Triggers
Clusters of ILI on more
than one continent other
than North America (WHO
Phase 5/Federal Stage 3).
or
Increased numbers of
suspect cases located in
multiple locations within
the U.S. highly suggestive
of human-to-human
transmission.
or
Few scattered numbers of
suspected cases around the
U.S., but with an unusually
high mortality rate or
significant morbidity.
Human-to-human
transmission is possible.
or
Suspected cases are being
reported within the
jurisdiction’s state as well
as elsewhere.
Overview
A pandemic or a severe
epidemic is occurring. It has
not yet reached the
jurisdiction. However, its
arrival is imminent.
Triggers
Clusters of ILI are being
reported in North America
and elsewhere (WHO Phase
6/Federal Stage 4)
or
Increased numbers of
suspect cases located in
multiple locations within the
U.S. highly suggestive of
human-to-human
transmission and beginning
to encroach upon the
jurisdiction’s state.
or
Multiple scattered
suspected/definitive cases
around the U.S., but with an
unusually high mortality rate
or significant morbidity.
Human-to-human
transmission is probable.
or
Suspected cases are being
reported in the jurisdiction’s
region as well as elsewhere.
Human-to-human
transmission is likely.
or
Sentinel event occurs within
the jurisdiction.
Overview
Active and passive
surveillance have revealed
the pandemic or epidemic
has arrived in the
jurisdiction.
Triggers
Major increase of ILI cases
in and around the
jurisdiction (WHO Phase
6/Federal Stage 5).
or
Infectious disease outbreak
or epidemic has reached the
jurisdiction. Numbers are
few. Infrastructure is not
compromised.
Triggers
Ongoing
or
Number of cases increases
and appears related to the
sentinel event.
