In today’s lesson, the students modeled a disease outbreak through an activity where they spread an “infection” through the class by sharing contents of a cup with one another. At the start of the activity, only one of the students was “infected” and through multiple rounds, the infection spread. By the third round, eight students were infected! After graphing their results, they realized that the number of infections was doubling every round, and learned that this is called exponential growth. Disease can spread very fast and quickly infect a very large part of a population. We ended the lesson by focusing on healthy habits or methods of prevention and elimination efforts. So far, only one human disease has been successfully eradicated through vaccination: smallpox. Guinea worm, though not through vaccinations, is also very close to being eradicated!
Propagación de Enfermedades Infecciosas
Terminamos la clase hablando sobre hábitos saludables o métodos de prevención. Hasta ahora, la única enfermedad humana que ha sido exitosamente erradicada a través de la vacunación, es la viruela. La enfermedad por el gusano de Guinea está muy cerca de ser erradicada. Translated with Google Translate
