My 3 month old has flu. If he is not running fever anymore could he still pass the virus on to my 5yr old?

Depends on situation: Most of those with the flu will shed the virus in their oral secretions or by cough in droplets for 7-10 days regardless of fever. The use of tamiflu (oseltamivir) will often drop a fever and it has some value in preventing flu when taken by uninfected family members. ...Read more

When I get fever, body pains, etc…, does the fever cause the body pains or does the  flu virus cause the body pains?

No pain due to fever: Fever is part of the body's response to infection, mediated by the release of chemicals (cytokines) from inflammatory cells directed against the agent causing infection. The same is at least partially true for the muscle pain, although there may be some breakdown of muscle cells by the virus (myositis). ...Read more

Have body aches and fever of 102. Could it be a virus or the flu?

Have body aches and fever of 102. Could it be a virus or the flu?

Yes to both.: It very well could be a virus. Influenza, or the flu, is a common virus that can cause these symptoms, and we are still in season for this virus to be going around. It also could be another virus as well. Get plenty of rest and drink fluids to keep hydrated. Tylenol (acetaminophen) or Ibuprofen can help reduce the fever. If it is not getting better within a few days, seek medical attention. ...Read more

Not the virus: directly, but physiological or psychological stress can affect the hormones that regulate your menstrual cycle. Having an occasional late, early or different menstrual period is quite common. I notice that you say you have a low thyroid but I don't see that you're taking any thyroid replacement. Untreated thyroid disorders can also affect menstrual cycles. Dr. Anne ...Read more
