Cough and cough again

Today really very tire. Need to talk for 8 hours. It has caused my cough more worst.
Think my cough virus has spread to the department. Yesterday one staff got cough went to see doctor in the morning. Today afternoon still not well and see doctor again. The new staff also got the fever and cough. He went home early to see the doctor. Hopefully the cough virus will not spread to all the staffs.
