The H1N1 flu virus is spread through infected droplets from coughing or sneezing and can be passed through contact with contaminated surfaces. Schools in Mexico were closed for weeks to prevent the spread of the virus, disrupting education. While private schools sent homework home, public schools were unable to provide continued education. As a result, the school year was extended into July. With colder weather approaching, the risk of the flu spreading increases, so continued preventative measures are important to protect the education system.
