Following VTV24 News Center in recent days, we cannot miss the weekly point about fake news that is confusing public opinion besides the complicated developments of the Covid-19 epidemic. Preventing the epidemic on the propaganda front is also a way. However, when there was information about the Covid-19 virus epidemic in the media, the first factor was to be true. But some people want to be "heroes" in public opinion by being quick and hasty, which can easily cause consequences for everyone. In about 20 cases, they have been sanctioned for administrative violations under Decree 15/2020/ND-CP for taking advantage of social networks to provide and share fake and untrue information. Some people have mistakenly and misunderstood themselves, taking pride in the fact that they have "reported faster than the newspapers" about COVID-19 cases. There are many cases of giving accurate information according to published sources from the mass media, but accompanied by comments that cause anxiety and fluttering for viewers and listeners. Instead of pointing out measures, each person needs to raise their own awareness of disease prevention, capture information from secure and reliable sources. With the current information about the COVID-19 epidemic, such arbitrariness and irresponsibility can lead to unpredictable consequences. As a fake news-free social network, be a responsible and selective user.
