Doctor discusses Hillary Clinton's pneumonia diagnosis

Clinton's doctor says she was diagnosed with pneumonia Friday

JACKSONVILLE, Fla. – Hillary Clinton has been diagnosed with pneumonia. She was seen stumbling as she left a September 11 commemoration event. She was also dehydrated. 

The incident occurred just days after Republicans argued that moments when Clinton coughed along the campaign trail were signs of a more serious health issue. Her campaign said she suffered seasonal allergies.

In statement Sunday, Clinton's doctor said the democrat nominee was diagnosed with pneumonia Friday. 

Dr. Jonathan Kantor says pneumonia is not usually a serious illness.  He says the first sign of pneumonia is typically a cough. 

"Certainly for pneumonia you think of a cough.. cough doesn't go away... feels really deep-seated and ultimately becomes what's called a productive cough," said Dr. Kantor. 

Kantor says for those who are over 65-year-old should probably see their doctor if they have a productive cough and a fever that won't go away. 

Kantor says people 65-years-old and older should consider getting a pneumonia vaccine. He says those in their upper 50s, early 60s should think about getting the vaccine, as well. 

The Centers for Disease Control and Prevention does recommend the vaccine for all children younger than 5 and adults 65 years or older.
