I am a security guard, and a secret receiver checked my health code. Am I also a secret recipient?

According to the requirements of epidemic prevention and control, if close contacts have been to the same place, they need to report to the local community, because the gas exhaled by the human body will also carry viruses, which will float into the nearby air with the air, so the people with confirmed cases are still at risk of infection if they come into contact with polluted environment and articles. It is suggested that after self-screening, if it is confirmed that the close contacts have been to the same place, they should report it as soon as possible and then stay at home. If you find symptoms such as fever, chills, fatigue, diarrhea and conjunctival congestion, you need to seek medical attention in time. You should also take preventive measures during the medical treatment, such as wearing a mask, and don't take public transportation or walk to avoid infecting others.
