Both my wife and I have had a persistent cough after travelling to Annapolis, MD 3 weeks ago. The cough started out as a dry hacking cough and has progressed to some fluid build up in the lungs that is most prevalent after rising in the morning. Neither of us have a fever but we are generally lethargic with periodic coughing spells during the day. Sputum in the morning is grayish white in color with no blood. Concerned about possible TB exposure while travelling 4 weeks ago.
