What flu is going round?

Does anyone know which species of flu is currently doing the rounds? My sister traveled in the car with me for four hours last Saturday, coughing and sneezing the fulltime, and now I have a horrible cold and an even worse cough. Can't stop coughing (this bug combined with herceptin cough) and can't sleep as it keeps me awake. So if anyone else has had this (my sister is still sick almost a week later) and knows how long it lasts, I'd love to hear from you. Any ideas on stopping cough would help too. I'm using Airborne lozenges at the moment but they don't seem to be helping.
