早期RSV感染会增加婴儿哮喘的风险,特别是有过敏史;预防可减少病例。 Early RSV infection raises asthma risk in infants, especially with allergy history; prevention may reduce cases.

一项新的科学免疫学研究将婴儿早期的RSV感染与儿童哮喘的较高风险联系起来,特别是那些有过敏家庭史的儿童。 A new study in Science Immunology links early RSV infection in infants to a higher risk of childhood asthma, especially in those with a family history of allergies. 研究人员发现,RSV和遗传遗传风险共同引发有害免疫变化,增加了对过敏原的敏感性。 Researchers found that RSV and inherited genetic risk together trigger harmful immune changes, increasing sensitivity to allergens. 通过产妇接种疫苗或新生儿抗体治疗来保护婴儿,防止了这些免疫转移,表明RSV的预防可以降低哮喘发病率。 Protecting babies through maternal vaccination or newborn antibody treatments prevented these immune shifts, suggesting RSV prevention could reduce asthma rates. 专家们敦促更广泛地利用现有的措施改善长期呼吸道健康。 Experts urge wider use of available measures to improve long-term respiratory health.
