activity level, week ending Jan.
Three states experienced low influenza-like illness
activity -- Louisiana, Mississippi and Texas -- while 47 states and New York City experienced minimal influenza-like illness
It would logically separate women with actual H1N1 and those with influenza-like illness

Some surveillance systems report cases of influenza-like illness
as influenza without further explanation.
On 3 September 2003, the IDPH distributed a notice to infectious diseases physicians and infection control practitioners in the state recommending that the diagnosis of histoplasmosis be considered for patients with acute influenza-like illness
who lived near or recently traveled to the area of the bridge site.
Although the use of antivirals is usually recommended, few studies have assessed whether the early use of these agents after the onset of an influenza-like illness
prevents illness, attenuates symptoms, shortens the duration of illness, or decreases mortality in the LTCF setting.
It is unclear whether the risk for GBS (and influenza vaccine effectiveness) is similar for laboratory-confirmed influenza and influenza-like illness
or influenza-coded health care encounters.
Outpatient Influenza-Like Illness
Surveillance Network (ILINet) exceeded the national baseline level of 2.
During the flu season following their birth, 193 (17 percent) of infants were hospitalised for influenza-like illness
, 412 (36 percent) had only an outpatient visit for a respiratory cause and 555 (48 percent) had no flu- or flu-like episodes.
School-based influenza immunizations can directly and indirectly lessen influenza-like illness
, reported Dr.
In elderly people living in the community, well-matched vaccines were not significantly effective against influenza, influenza-like illness
, or pneumonia, but adjusted VE was 26% for preventing death from influenza and pneumonia, 29% for preventing hospital admissions for all respiratory illnesses, and 47% for reducing all-cause mortality.
