Is h3n2 serious?
Some people are at an increased risk for developing serious complications from the flu. These complications can include pneumonia or the worsening of a preexisting medical condition, such as asthma.
What is the most frequent complication of influenza?
The most frequent serious complications of influenza are pulmonary and fall into 4 categories: primary influenza pneumonia, secondary bacterial pneumonia, pneumonia due to unusual pathogens or in immunocompromised hosts, and exacerbations of chronic pulmonary diseases.
Does the flu cause long term lung damage?
We would further expect that individuals with the most severe forms of acute influenza illness will also be at greatest risk to develop chronic lung disease, perhaps with the same chronic inflammatory foci as we observed in the mouse model of this process.
How do you know if the flu has turned into pneumonia?
They can include:
- High fever, up to 105 F.
- Coughing up greenish, yellow, or bloody mucus.
- Chills that make you shake.
- Feeling like you can’t catch your breath, especially when you move around a lot.
- Feeling very tired.
- Loss of appetite.
- Sharp or stabbing chest pain (you might feel it more when you cough or take a deep breath)
Is H3N2 Type A or B?
Seasonal flu vaccines are formulated to protect against influenza viruses known to cause epidemics, including: one influenza A(H1N1) virus, one influenza A(H3N2) virus, one influenza B/Victoria lineage virus, and one influenza B/Yamagata lineage virus.
Can the flu cause neurological problems?
Influenza can be associated with various neurologic problems: encephalopathy (a state of confusion), seizures, neuropathy, as well as others. These complications most frequently occur in children, although cases of neurologic illness associated with adult influenza certainly occur.
Which respiratory tract complications are observed during influenza infection and why?
Uncomplicated human influenza virus infection causes transient tracheo-bronchitis, corresponding with predominant virus attachment to tracheal and bronchial epithelial cells. The main complication is extension of viral infection to the alveoli, often with secondary bacterial infection, resulting in severe pneumonia.
How do you know when flu is serious?
In adults, symptoms of life-threatening flu complications include:
- feeling short of breath.
- trouble breathing.
- disorientation.
- feeling suddenly dizzy.
- abdominal pain that is severe.
- pain in the chest.
- severe or ongoing vomiting.
Is H3N2 more severe?
Conclusions: Influenza A H3N2 infection was more severe than A H1N1 or B in terms of fever, leukopenia, and C-reactive protein. Myalgia and other symptoms such as fever, headache, general malaise and sore throat were equally frequent in influenza A H3N2, A H1N1, and B infections.
Can flu cause permanent damage?
If you’re young and healthy, the flu usually isn’t serious. Although you may feel miserable while you have it, the flu usually goes away in a week or two with no lasting effects. But children and adults at high risk may develop complications that may include: Pneumonia.
Does flu damage the brain?
It’s further evidence to support the idea that viral infections can damage the brain, Smeyne says, but there’s still no slam-dunk study that demonstrates a virus can cause Parkinson’s, or Alzheimer’s, or any number of other neurological disorders.
What autoimmune disease makes you feel like you have the flu?
Systemic lupus erythematosus (disorder in which the body attacks its own healthy cells and tissues)
