Young people generally think that they have good physical fitness and are not easily infected. Therefore, these issues are often not paid attention to. At present, the number of infected people in African countries is also increasing. We must not only pay attention to them, but also take protective measures. Now that COVID-19 has attracted the attention of the whole country, places like the United States and Brazil have also begun to pay attention to protection. They have also realized that they cannot go their own way and are responsible for themselves and the world.
