CDC H1N1 Flu Website Situation Update, August 21

updates from the Centers for Disease Control and Prevention (CDC).
Updated Guidance for Businesses and Employers
CDC has released new guidance that recommends actions that non-healthcare
employers should take now to decrease the spread of seasonal flu and 2009
H1N1 flu in the workplace and to help maintain business continuity during the
2009–2010 flu season. The guidance includes additional strategies to use if
flu conditions become more severe and some new recommendations regarding when
a worker who is ill with influenza may return to work. This guidance is
available on the CDC website and on Flu.gov.

Updated Guidance for Institutions of
Higher Education
CDC has released new guidance to help decrease the spread of flu among
students, faculty, and staff of Institutions of Higher Education (IHE) and
post-secondary educational institutions during the 2009-2010 academic year.
The guidance expands upon earlier guidance for these settings by providing a
menu of tools that IHE and health officials can choose from based on
conditions in their area. It recommends actions to take now (during this
academic year), suggests strategies to consider if flu severity is increasing
compared with the spring/summer 2009 outbreak, and provides a checklist for
making decisions. This guidance is available on the CDC website and on
Flu.gov.

Key Flu Indicators
Each week CDC analyzes information about influenza disease activity in the
United States
and publishes findings of key flu indicators in a report called FluView. During the week of August
9-15, 2009, a review of these key indictors found that influenza activity had
decreased slightly in the United
States from the previous week. However,
there were still higher levels of influenza activity than is normal for this
time of year. Below is a summary of the most recent key indicators:
- Visits to doctors
for influenza-like illness (ILI) were
highest in February during the 2008-09 flu season, but rose again in
April 2009 after the new H1N1 virus emerged. Current visits to doctors
for influenza-like illness are down from April, but are higher than what
is expected in the summer.
- Total
influenza hospitalization
rates for adults and children remain low and are well below the seasonal
winter-time average of the last four years.
- The
proportion of deaths
attributed to pneumonia and influenza (P&I) was low and within the
bounds of what is expected in the summer.
- Most
state health
officials are reporting local or sporadic influenza activity. Two
states are reporting widespread influenza activity at this time. Any
reports of widespread influenza activity in August are very unusual.
- Almost
all of the influenza viruses
identified were the new 2009 H1N1 influenza A viruses. These 2009 H1N1
viruses remain similar to the viruses chosen for the 2009 H1N1 vaccine
and remain susceptible to antiviral drugs (oseltamivir and zanamivir).

CDC discontinued reporting of individual
confirmed and probable cases of novel H1N1 infection on July 24, 2009. CDC
will report the total number of hospitalizations and deaths weekly, and
continue to use its traditional surveillance systems to track the progress
of the novel H1N1 flu outbreak.

International Situation Update
This situation report provides an update to
the international situation as of August 21, 2009. As of August 13, the World
Health Organization (WHO) regions have reported over 182,166
laboratory-confirmed cases of 2009 H1N1 influenza virus (2009 H1N1) with
1,799 deaths. The laboratory-confirmed cases represent an underestimation of
total cases in the world as many countries now focus surveillance and
laboratory testing only in persons with severe illness. The 2009 H1N1
influenza virus continues to be the dominant influenza virus in circulation
in the world. Decreases in disease due to 2009 H1N1 continue to be reported
from South America and parts of Australia. The United Kingdom
is also reporting national decreases in disease due to 2009 H1N1. In contrast,
disease associated with 2009 H1N1 influenza is continuing to increase in
southern Africa and more Africa countries
have reported their first cases. In addition, 2009 H1N1 continues to
circulate in tropical countries.

2009-2010 Academic Year and suggestions on how to use them. The guidance
is designed to decrease exposure to regular seasonal flu and 2009 H1N1

academic activities that go on in Institutions of Higher Education
(IHE). CDC will continue to monitor the situation and update the current
guidance as more information is obtained on 2009 H1N1.
- UPDATE: Novel H1N1 Flu: CDC Response
CDC is taking aggressive action to
respond to the new 2009 H1N1 influenza virus and a possibly severe
upcoming flu season. CDC's response goals are to reduce the spread and
severity of illness, and to provide information to help health care
providers, public health officials and the public address the challenges
posed by this public health threat. While the timing, spread and
severity of the upcoming U.S.
flu season are uncertain, CDC anticipates that 2009 H1N1 influenza
viruses and regular seasonal influenza may spread at the same time. It's
possible that a lot more people will get sick this season than normally
occurs during a regular flu season. There also may be more people
hospitalized and more deaths this season than during a normal flu
season.
