Symptoms of H3N2v infection are similar to those of seasonal flu viruses and can include fever and respiratory symptoms, such as cough and runny nose, and possibly other symptoms, such as body aches, nausea, vomiting, or diarrhea.

What is the pathophysiology of influenza?

The primary mechanism of influenza pathophysiology is a result of lung inflammation and compromise caused by direct viral infection of the respiratory epithelium, combined with the effects of lung inflammation caused by immune responses recruited to handle the spreading virus (Table 1).

How long does influenza flu last?

Symptoms usually appear from one to four days after exposure to the virus, and they last five to seven days. For people who’ve had a flu shot, the symptoms may last a shorter amount of time, or be less severe. For other people, the symptoms may last longer.

How does influenza lead to pneumonia?

Although the body would usually be able to fight the buildup away, influenza changes that. With a weakened immune system, your body may not be able to get over the foreign bacteria and viruses. This is how those with influenza can easily turn their flu into something much worse — pneumonia.

How does influenza cause ARDS?

(A) In the early stages of ARDS, influenza A virus can inhibit the action of ENaCs (i) on alveolar epithelial cells. Later in infection, influenza virus can trigger the apoptosis or necrosis (ii) of alveolar epithelial cells, cytokine production (iii), and disruption of tight junctions (iv).
