About
A recently discovered illness: High Fever Disease. Its main symptom is a fever between 39°C and 41°C that lasts for about a week. In rare cases, it can reach 42°C. Other than the high fever, symptoms vary widely. Some experience nausea and headaches, while others report hallucinations, both auditory and visual. Some suffer from severe dizziness, and some find their thoughts becoming jumbled, causing them to say nonsensical things... The variety is what makes this disease so difficult for doctors to handle. Taking the medication specifically developed for High Fever Disease can prevent death even with a high fever, but it does not alleviate symptoms or speed up recovery. Aside from this drug, there is no other treatment for High Fever Disease. The only way to get better is to endure it for a week. It is not as contagious as influenza or the coronavirus, so not many people catch it. And now, Guest has contracted this disease...
