Watch the people on the street – watch them, and see how many cover their mouth when they cough. The simple act of putting your hand, tissue or a cloth over your mouth when coughing can help prevent the spread of certain diseases.
During an evacuation, and large groups of people are living in a shelter, communicable diseases can spread quickly. It is important that every person do their part to ensure the health and safety of those around them. One person that is staying in a shelter, and has Tuberculosis, has the potential of infecting dozens and maybe even hundreds of other people. After the shelter is closed and those people return home, they also bring their new infection with them, thus helping to spread the disease.
