發燒退了反而要小心？醫師解析登革熱的關鍵病程與危險警訊

Dengue fever is a common infectious disease in summer, especially after heavy rains in southern Taiwan, requiring extra caution. Many people mistake it for a common fever or a simple mosquito bite, but the most troublesome aspect of dengue fever is its potential for sudden deterioration. A crucial medical concept is that "fever reduction does not mean recovery." The most dangerous period of dengue fever often occurs around the 3rd or 4th day of illness, around the time the fever begins to subside. If, after the fever subsides, symptoms such as increased weakness, persistent vomiting, abdominal pain, or bleeding occur, it may indicate "plasma leakage" from blood vessels, which can even lead to shock in severe cases. This video summarizes the transmission methods of dengue fever, the warning symptoms to be aware of, and most importantly—when you absolutely cannot wait and must go to the emergency room immediately.
