WHAT IS Influenza (Flu)?

Influenza (Flu) is a viral infection that attacks your respiratory system, nose, throat, and lungs. Influenza is commonly called the flu, but is different from the stomach flu viruses that cause diarrhea and vomiting.

Influenza usually resolves on its own, but  sometimes it can cause  complications which can be deadly.



The flu may seem like a common cold  at first but colds usually develop slowly, whereas the flu tends to come on suddenly. 

Common signs and symptoms of the flu include:

  • Fever over 100.4 F (38 C)
  • Aching muscles
  • Chills and sweats
  • Headache
  • Dry, persistent cough
  • Fatigue and weakness
  • Nasal congestion
  • Sore throat

eStudySite engages in investigative clinical trials of medications treating Influenza (Flu). Qualified subjects participating in a trial receive study-related medical evaluations  and the investigative study medication at no cost, and may be eligible to receive financial compensation for time and travel cost.
