Nowadays, the Covid-19 Pandemic has become more and more complicated and many people have died of this pandemic, so we must have real effective solutions to prevent its spread. First and foremost, we should wear facemasks when going outside and communicating with others. This way can help to slow the spread of the virus. Moreover, it can help keep people from transmitting or catching the germ of disease. Secondly, we should keep the distance between two people at least two meters when communicating. Many people don't have any symptoms of the virus, so they often go out and easily infect others. Therefore, maintaining social distancing is very necessary. Last but not least, we should install the app "Bluezone". It is an application that warns us about close contact with anyone infected with Covid-19 and helps to minimize the risk of community spread. When there is an infected case, we can immediately know if we have ever contacted this person. The more people install "Bluezone", the higher the efficiency in preventing the pandemic we will get. In short, you should follow these tips to protect yourself and also others.
