What should I do if I receive a text message from the CDC for no reason?

This morning, I suddenly received a notification message from Hubei CDC106551KLOC-0/,saying that I might have direct or indirect contact with infected people in COVID-19 and asked to report to the community.

You scared me! I opened my health code at the first time and saw it was a green code. Then I checked my communication itinerary, and it didn't show that I had been to the middle and high risk area. I have been staying in Wuhan (a non-risk area) and I can't figure out how I received this message.

Then I looked it up on the Internet, and many people also received this kind of message. Some people have never been to Hubei at all, and some people said that it was caused by Unicom's failure after consulting.

But I couldn't put my heart down at all, so I kept calling the hotline of Hubei CDC and finally got through. The operator also skillfully asked me which district I was in, and the answer was Wuhan. Later, he asked me to check it, which may be caused by a malfunction, but I can't check it until I go to work on Monday.

Ask the landlord about the requirements of the community and say that he has never been to the risk area. Stay at home for the next two days and wait for the result.

Has anyone else encountered this situation? How did you do that?

What should I do if I receive a text message from the CDC for no reason?

Is time and space coming again? My heart is always uneasy. I suddenly received a text message in the morning, which was sent by the CDC. This roughly means that I may have had contact with infected people in COVID-19 and need to report to the community. I was shocked when I received the text message. I subconsciously looked at my health code and it was still green. Then I reported to the community in the community group, and all the staff in our community were in the group. At noon, I received a strange phone call from the circulation staff. The phone content is also very simple. First, I asked if I had been to the epidemic area, then I asked my current address, and then I hung up the phone. I always look at my health code, and it's still green. I still remember last year's time and space. My health code will not change color, will it?
