Types and Surface Glycoproteins of Influenza Types: ABC
Surface Gylcoproteins: H & N
Human Influenza Viruses B&C
Influenza A A is primarily Avian, but can infect human and other animals
Is further classified by H and N subtypes
Influenza High Risk groups Young <24 months; 6 months-5 years
Older Adult >50
Long Term Care
Pulmonary Dx
Cardiac Dx
Chronic Dx (DM, CKD, Hepatic, Heme)
Immunosuppressed
Pregnacy and Immediate Post partum
Morbid Obesity (BMI>35)
Severe Complications of Influenza Pulmonary Compliacations
Sepsis
AKI
MODS
Lymphopenia, Thrombocytopenia
DIC
Rhabdo
,Organ-specific infections
Subjective Findings of Influenza Sudden onset symptoms
Fever (most common)
Chills, Rigors
HA
Myalgia
Malaise
Dry Cough
Nasal Discharge
Hoarseness
Sore throat
Special Subjective Considerations for Influenza Assess sick contact history
Assess travel exposure
PE of influenza Fever (>38.2)
Eyes watered/Reddened
Facial Flushing
Skin hot/Moist
Nasal mucosa hyperemic without exudate
Rales/Rhonci uncommon
Influenza testing Rapid Testing- low sensitivity, may not distinguish strains/subtypes
NAAT (few hours)
, higher sensitivity
Rapid test of choice
Viral Culture (2-3 days)
nasal, sputum ot tracheal secretions
higher sensitivity, but long wait
Additional Diagnostics for Influenza CXR: r/o secondary PNA
Lobular infiltrates are rare
CBC may show leukopenia
Influenza in Older Adults Atypical Presentation:
Altered MS
Cough
Fever
Less Resp Sx; more complications
Less common: muscle aches, sore throat
Present with more GI sx than other resp viruses
Influenza Diff Dx Other URI
RSV, Adenovirus
Infective and Inflammatory conditions that cause resp and systemic symptoms
Influenza Acute Management Antiviral Therapy:
Zanamivir (inhaled)
