How many days after flu onset would bacterial pneumonia begin?

How many days after flu onset would bacterial pneumonia begin?

At risk: Once the inner lining of the lung is infected, it is prone to a secondary infection. It may take weeks to recover from influenza, and a secondary pneumonia can occur at any time during that period. There is evidence that the risk for a pneumococcal pneumonia occurs even one week after influenza infection.

Daughter has bacterial pneumonia and step bacteria was identified. Is it contagious? Especially if coughed on?

Daughter has bacterial pneumonia and step bacteria was identified. Is it contagious? Especially if coughed on?

Not particularly: Many of us have strep pneumo germs in our nasal passages periodically as hitchhiker germs. They can sit there and do nothing or take advantage of a deep chest cold and trigger pneumonia. Some germs like chickenpox travel easily in the air and transfer easily, this does not. Simple droplet precautions avoid transfer, but even if you have some on board, you don't necessarily get sick. ...Read more

Can a child with bacterial pneumonia go swimming?

Can a child with bacterial pneumonia go swimming?

Not advised: The child's respiratory capacity may be compromised, making them more prone to tiring and then risk of accidental drowning. With bacterial pneumonia, there is usually a fair amount of fluid in the lungs, and thus the capacity may be compromised. It would be ok to dangle feet in the water, but i wouldn't advise actual swimming until done with medicine and cleared by doctor. ...Read more

Their immune systems are sometimes not capable of fighting off the infection on their own and therefore should be treated appropriately in consultation with your doctor. For complicated/difficult cases in children, it may require the expertise of a pediatric pulmonologist to guide therapy. ...Read more
