Last week I travelled by public means in a bus. My journey was quite long as it was about 400km. Unfortunately, I sat next to someone who had a continuous productive cough but he was furious whenever I asked him to open the window. Since there was an empty seat elsewhere, I moved for fear of acquiring TB should he have been a case. Do you have policies in your countries regarding the conduct of the passengers particularly with regard to prolonged cough in a public vehicle? Please share the experience in your country.
