“How does he get flu?” is a question that’s been asked more than 40 times in the past week.
The questions aren’t rhetorical.
Flu pandemic season is in full swing and the flu vaccine is still under development.
But the question is still being asked, and there are some signs that some of the flu symptoms that come with the flu may not be as readily apparent as they might be for some.
“What happens in the brain is a different story,” said Dr. Scott G. Davis, professor of neurobiology at the University of Colorado School of Medicine.
Dr. Davis has been studying the neural responses of people with flu symptoms for many years and says the symptoms of flu flu in this case don’t appear to have the same neurological consequences as those of flu in other illnesses.
Dr., Davis said in a phone interview that the flu virus causes inflammation in the central nervous system that causes inflammation of certain parts of the brain.
It can also cause inflammation in areas of the nervous system known as the spinal cord, causing numbness or tingling sensations in parts of your brain.
When a person experiences these symptoms, the brain’s immune system attacks them, causing the flu to appear in the body.
But when people with symptoms don’t get the flu, the immune system doesn’t attack them as it does when people are healthy.
This allows the flu viruses to remain in the system and infect other people.
It also allows the immune systems to spread through the body, which is the way it’s done with other infections.
The symptoms of the common flu include fever, runny nose, headache, cough and a sore throat.
People who are sick with flu are at increased risk for other illnesses, such as pneumonia and meningitis, which can be serious, according to Dr. David M. Susskind, an infectious diseases physician and professor at the Icahn School of medicine at Mount Sinai.
“The symptoms of influenza are a bit different than the symptoms you see in a person with a cold, or a person who’s getting a cold,” Dr. Sommersaid.
“You don’t see fever, you don’t have the cough, and the symptoms tend to be milder than those of a person getting the flu.
You don’t want to get the virus.”
Dr. Andrew J. Smith, professor and chair of the department of immunology and immunology at the Howard Hughes Medical Institute, also has studied flu symptoms.
He said the symptoms in flu are similar to the symptoms that occur with a virus.
For instance, you may feel cold and flu-like symptoms, he said.
But in the cases where there’s no flu virus present, you might feel the flu-associated symptoms, such the cough and sore throat that are part of flu-related symptoms.
Dr Smith said it’s not the flu itself that causes the symptoms, but the way that the body responds to the virus.
“In the case of flu, you’re getting symptoms, and you’re responding to the infection, and it doesn’t necessarily make you sick,” Dr Smith told CBS News.
“It can be the response to the flu.”
But what’s the difference between a flu virus infection and the typical flu symptoms?
Dr. Margo Schaffer, a professor of neurology at the Johns Hopkins University School of Neurology and neurosurgery, agrees that the difference in flu symptoms and flu virus infections can be a bit of a blur.
“When we talk about flu, we’re talking about flu that you have,” she said.
“People who have the flu have a high-risk for complications, and that can be life-threatening or even fatal.”
But, Dr. Schaffer said that if you’re not having flu symptoms, you likely don’t need to worry.
Dr Davis said the difference might come down to what happens when a person is infected with a viral infection, such that the immune response is compromised.
“I would argue that the typical viral infection that people experience is just as dangerous as the flu,” he said, “but there is an extra component that is not as well understood.
It’s that part of the immune cell that is called T-cells.”
T-Cell is the part of a cell that helps the body fight infections.
When that immune cell is compromised, the body will respond by producing more T-cell cytokines that can attack other cells in the immune chain.
This inflammation can lead to other illnesses including pneumonia, meningococcal disease, and influenza.
But what happens if that same immune cell doesn’t have enough T-cytokines to kill off the other cells?
“We don’t know what the mechanisms are that allow this immune cell to be so damaged,” Dr Davis explained.
The cells in question can be activated by certain chemicals that are released by the immune cells, but they can also be damaged by certain proteins that are produced by the body and help the body defend itself
