新的研究表明,通过阻碍病毒的复制,发烧可能有助于抗击流感。 Fever may help fight flu by hindering virus replication, new study suggests.

根据剑桥大学的研究,发烧是许多物种的自然免疫反应,通过创造不利于复制的环境,可以直接帮助抗击流感等病毒。 Fever, a natural immune response across many species, may directly help fight viruses like influenza by creating an environment less favorable for replication, according to University of Cambridge research. 科学家设计了抗热的人类流感病毒,并用老鼠进行测试,老鼠不会自然发烧。 Scientists engineered a heat-resistant human flu virus and tested it in mice, which don’t naturally develop fevers. 在高温模拟热的情况下,正常的病毒挣扎着致病,而耐热的病毒仍然有效,仅表示温度就能够抑制某些病毒。 Under elevated temperatures simulating fever, the normal virus struggled to cause illness, while the heat-tolerant version remained effective, suggesting temperature alone can inhibit certain viruses. 研究结果支持了发烧演变为防御机制的想法, 挑战病毒感染期间使用乙酰氨基苯等降低发烧药物的常规使用。 The findings support the idea that fever evolved as a defense mechanism, challenging the routine use of fever-reducing drugs like acetaminophen during viral infections. 专家们告诫说,虽然结果很有希望,但人类的反应可能不同,需要开展更多的研究,以确定管理发烧的最佳办法。 Experts caution that while the results are promising, human responses may differ, and more research is needed to determine the best approach to managing fever.
