Yuki's nest:

Last May, I owned it. My muscles hurt so much that I feel pain when I walk. The point is that my muscles ache all over. I have a cold and fever for nearly a month. The point is that my lymph nodes are beginning to swell, and taking medicine doesn't help. I was really scared at that time. I suspect that I was bitten while climbing a mountain in Krabi Rainforest, because I started to have a fever about the third day after climbing the mountain. . Then I cured myself. . May the patient recover.

24476: Is dengue fever not spread by mosquitoes? What does it have to do with hygiene? Take ten baths a day. You should be bitten, and you will be bitten.

Night cold zero point: the number of people treated in isolation has not changed much, and the treatment and infection are basically the same.

Little Prince: It's always good to pay attention to hygiene.
