I can help! In your first sentence you should change "disaster" to "disasters," because it is plural in this case. I am assuming that you meant to say that the disasters were harming the travel industry, so I would not say "cause treat," I would say, "that cause problems for" . In the beginning of your second paragraph, you should say, "from the start of January," because "start from the January," is a bit of an unnatural sentence. Instead of saying "the threaten of the corona virus," you should say "the threat of the Coronavirus." Coronavirus is one word, so be sure to combine it, and possibly capitalize it. You should remove the S after the apostrophe in the same sentence, because the s only goes after the ' if s is not present at the end of the word, with some exceptions. Lastly, you should change "that they feel anxious on the travel," to "that they feel anxious traveling in the United States." I'm sorry that I could only respond in English, and I did not correct everything, but I hope this helps.
