People who got sick experienced chills, fever, and muscle aches. It was spread through coughing and sneezing. About 50 million people died worldwide. This pandemic taught us that following public health guidelines is crucial to saving lives. Part 2 During the Spanish Flu, some people misbehaved and ignored health guidelines. This led to a very high infection rate and many deaths. Following guidelines such as wearing masks and washing hands can help stop the spread of disease. I think it is important to listen to health experts, especially during a pandemic. Part 3 Vaccines are important because they protect people from getting sick. For example, smallpox used to kill millions of people every year. Before the vaccine, there was no way to prevent it. After the vaccine was developed, the disease was completely wiped out in 1980. This shows that vaccines can save countless lives and even make a disease disappear forever. 1 学科网（北京）股份有限公司 $
