People suffering from communicable diseases should not urinate, defecate or spit in open because it may lead to spread of varieties of bacteria and virus. They should cover their mouth and nose while sneezing or coughing so that there will be less chance of spread of germs. These diseases spread when a diseased person spread space with others.
