The Flu Season is upon us!
Influenza A(H1N1)pdm09 virus infection was associated with significant morbidity (the condition of being sick), mainly among children and young adults. The majority of patients had self-limited mild-to-moderate uncomplicated disease. However, some patients developed severe illness and some died. In addition to respiratory complications, several complications due to direct and indirect effects on other body systems were associated with influenza A(H1N1)pdm09 virus infection. The main complications reported in hospitalized adults with influenza A(H1N1)pdm09 were pneumonia (primary influenza pneumonia and concomitant/secondary bacterial pneumonia), exacerbations of chronic pulmonary diseases (mainly chronic obstructive pulmonary disease and asthma), the need for intensive unit care admission (including mechanical ventilation, acute respiratory distress syndrome and septic shock), nosocomial infections and acute cardiac events. In experimentally infected animals, the level of pulmonary replication of the influenza A(H1N1)pdm09 virus was higher than that of seasonal influenza viruses. Pathological studies in autopsy specimens indicated that the influenza A(H1N1)pdm09 virus mainly targeted the lower respiratory tract, resulting in diffuse alveolar damage (edema, hyaline membranes, inflammation, and fibrosis), manifested clinically by severe acute respiratory distress syndrome with refractory hypoxemia. Influenza A(H1N1)pdm09-related pneumonia and other complications were associated with increased morbidity and mortality among hospitalized patients.
I was unfortunate enough to contract this bug back in late September, and that was right before I had gotten a shot. I can attest to the fact that this is not a very nice bug to get as I was laid up for over a week, before then contracting pneumonia. The whole ordeal took about four weeks to recover from!
Today (December the 15th), some early reports indicated that not a few states were moving from sporadic and low to moderate and even higher levels of infection! And yes, it's not too late to get a vaccine shot at your nearest clinic. And, the good news is that this years 'blend' turned out to be just the right 'medicine'! Remember, after getting your shot, that it will take up to two weeks before your immune system is geared up to fight the real thing. And while getting this vaccine may not keep you from catching the flu, it will certainly take the effects and symptoms down a few pegs!
