Note when you suspect the possibility of Covid-19 infection

When you suspect that you may be spreading an infection from someone infected with Covid-19, take the following precautions to protect yourself and the community's health:

1. You need to wear a mask regularly

Wearing a mask is essential for both infected and uninfected individuals to prevent the new coronavirus. The most important goal of wearing a mask is to protect others. If you get sick yourself, a mask will help prevent secretions from coming out rather than protect yourself from outside influences.

You also need to pay attention to using the mask properly in terms of wearing, removing, editing as well as choosing the right type to optimize to prevent infection.

In addition to masks, you should also pay attention to cover your mouth and nose when coughing and sneezing, do not share personal utensils or eating utensils, wash your hands often with soap or antiseptic solution.

2. You should always be honest when making a report

One of the most important and recommended actions when in close contact with a Covid-19 infected person is the honesty of making a report. Report symptoms of Covid-19 infection caused by SARS-CoV-2, and share your travel schedule with your healthcare provider. You should report as soon as possible even if symptoms are mild or unclear.

We need a greater sense of truth in reporting truthfully to health workers. If you are in contact with someone infected with Covid-19, do not hesitate to notify anyone who has contact with you.

After learning that they have been in close contact with the Covid-19 case, many people easily fall into psychological instability and fear of stigma and tend to avoid isolation. In fact, dishonest behavior or statements will not only hurt you but also harm others. During an outbreak, honest reporting is essential to protect everyone around, as well as to support the state in disease prevention.

3. You will be categorized as quarantine

When you suspect the possibility of Covid-19 infection, you need to know how to classify the quarantine in order to promptly implement the necessary quarantine measures. If the person infected with Covid-19 is F0 then those who are in close contact with F0 are F1 (suspects). Those exposed to F1 were F2, similar to those exposed to F2 was F3.

Each category F has different recommendations for epidemic quarantine, and must notify other Fs of their status.

If you know how to act properly when you discover that you have been in close contact with someone infected with Covid-19, you will remain calm and calm to deal with the worst possible situations. Do what you should do quickly to prevent Covid-19 and avoid putting pressure on an infected person. After all, any of us can unintentionally become F0 so never discriminate against a Covid-19 infection.
