Why did Hillary hug a child while suffering from pneumonia? Candidate embraced young girl despite having a contagious illness

Hillary Clinton embraced a young child after leaving her daughter's apartment despite suffering from pneumonia. The Democratic presidential candidate was diagnosed with the illness after she collapsed at a 9/11 ceremony. Pneumonia is a contagious illness that is spread from person-to-person when small droplets of water that contain the bacteria get into the air and people breathe them in. Those infected usually spread the disease by sneezing while in close contact with others, who then breathe in the bacteria. Clinton was diagnosed with pneumonia on Friday and given antibiotics but had become dehydrated at the event in New York.
