随着冬季的到来，呼吸道疾病的发病率也随之上升。许多人在感染后会出现高热、畏寒等症状，但最近，一位名叫徐女士的患者却出现了反复低烧的情况。她的体温每次都在37.5℃，两三天就会消退。经过病原体检测，发现这并不是近期常见的病毒感染。
徐女士告诉记者，她的“背后发烫、睡觉出汗”，虽然体温不高，但却给她带来了极大的不适。这种情况在医学上被称为“低烧”，通常是由于身体内部的炎症反应引起的。然而，持续的低烧并不正常，需要及时就医。
专家指出，有两类人群需要格外警惕持续低烧的情况。一是老年人和儿童，他们的免疫系统相对较弱，更容易受到疾病的侵袭。二是有慢性疾病的人，如糖尿病、心脏病等，他们的身体对炎症的反应可能会更强烈。
此外，如果低烧伴随着其他症状，如咳嗽、喉咙痛、头痛、乏力等，也需要及时就医。因为这些症状可能是某种感染或疾病的表现。
总的来说，虽然低烧可能是一种正常的生理反应，但如果持续时间过长或者伴有其他症状，就需要及时就医，以排除可能的疾病。同时，对于上述提到的两类人群，更应该密切关注自己的身体状况，及时就医，以免延误治疗。

Title: Winter Low-grade Fever Recursively, Two Groups Need to Be Alert!
Keywords: 1. Low-grade fever symptoms
Content: Title: Winter low-grade fever persists, two groups need to be extra vigilant
With the arrival of winter, the incidence of respiratory diseases also rises. Many people will experience high fever, chills after infection, but recently, a patient named Ms. Xu has been experiencing repeated low-grade fever. Her body temperature is always 37.5℃， and it subsides after two or three days. After pathogen detection, it was found that this was not a recent common viral infection.
Ms. Xu told reporters that her “back is hot and she sweats when she sleeps”, although her temperature is not high, it brings her great discomfort. This situation is called “low-grade fever” in medicine, which is usually caused by inflammation inside the body. However, persistent low-grade fever is not normal and needs timely medical treatment.
Experts pointed out that there are two groups that need to be extra vigilant about persistent low-grade fever. One is the elderly and children, whose immune systems are relatively weak and are more easily attacked by diseases. The other is people with chronic diseases, such as diabetes, heart disease, etc., their bodies may respond more strongly to inflammation.
In addition, if low-grade fever is accompanied by other symptoms, such as cough, sore throat, headache, fatigue, etc., it also needs timely medical treatment. Because these symptoms may be manifestations of certain infections or diseases.
In general, although low-grade fever may be a normal physiological response, if it lasts too long or is accompanied by other symptoms, it needs timely medical treatment to rule out possible diseases. At the same time, for the above-mentioned two groups, they should pay more attention to their physical conditions and seek medical treatment in time to avoid delaying treatment.
