夏秋换季儿童手足口病高发 疾控专家提示精准阻断三大传播渠道

Quick Look

夏秋换季为手足口病高发期。中国疾控中心提示,手足口病经消化道、密切接触及呼吸道飞沫传播,防控重点在于勤洗手、消杀通风、居家隔离及接种EV71疫苗。

Why It Matters

夏秋换季为儿童传染病高发期,手足口病由肠道病毒感染引发且传染性强,低龄儿童普遍易感。

夏秋换季是儿童传染病高发时段,手足口病更是困扰家长和幼儿园、中小学的常见问题。很多家长误以为手足口病只是“手脚长小疹子”的轻微小病,无需过度重视,实则该病由肠道病毒感染引发,传染性极强、传播途径多样,低龄儿童普遍易感,少数重症病例还可能引发并发症,危及孩子健康安全。

手足口病防控核心重在提前阻断传播,而非病后治疗。只要精准切断传播途径,落实科学防护,就能有效守护儿童健康。

认清来源:手足口病三个传播渠道

1.消化道传播(粪一口途径,核心传播方式)

这是肠道病毒最主要的传播渠道。感染病毒的孩子,粪便中会携带大量病毒,且排毒时间可持续数周。若便后未及时洗手,或家长护理后未消毒,病毒会附着在双手、餐具、玩具、门把手等物品表面。孩子接触污染物品后吃手、揉眼,或食用污染食物、生水,病毒就会侵入体内引发感染。

2.密切接触传播(高发日常传播方式)

患者的唾液、鼻腔分泌物、皮肤疱疹液中含有大量活性病毒。儿童共用毛巾、水杯、玩具、衣物,或直接接触患儿皮疹、口水,都会沾染病毒。在幼儿园、游乐场等儿童聚集场所,极易出现交叉感染和聚集性疫情。

3.呼吸道飞沫传播(最隐蔽传播方式)

患儿咳嗽、打喷嚏产生的飞沫会携带病毒悬浮在空气中,健康孩子近距离吸入即可感染。密闭、拥挤、通风差的室内环境,会大幅提升飞沫传播的风险。

精准阻断:四大核心措施切断传播链

1.勤洗手

手是肠道病毒主要传播媒介,督促孩子在饭前便后、外出归来、接触公共物品后,使用流动水配合洗手液按七步洗手法洗手,时长不少于20秒,纠正吃手、揉眼等不良习惯。免洗洗手液仅可应急,不能替代流水洗手,家长护理孩子、处理污物后同样需要做好手部清洁。

2.做好通风和环境消杀

日常对餐具煮沸消毒,玩具、门把手等高频接触物选用含氯消毒剂擦拭,配合暴晒处理织物,注意酒精对肠道病毒无效;居家、教室每日通风2~3次,每次不少于30分钟,保持室内干燥通风,减少病毒在密闭环境扩散。

3.患儿尽量居家

高发季节尽量减少儿童前往密闭人员密集场所,学校落实晨午检,出现发热、出疹、口腔溃疡等症状及时送医,严禁带病返校。患儿需居家隔离,污染物妥善处理,待症状痊愈后方可返园返校,避免持续传播。

4.及时接种疫苗,守住重症底线

EVA71灭活疫苗可有效预防该型病毒所致重症手足口病,建议6月龄—5岁儿童尽早全程接种。该疫苗不能覆盖全部肠道病毒血清型,接种后仍需坚持落实日常防护措施。

避坑指南:三大常见防控误区

很多感染源于认知误区,家长需重点规避:

误区一:只有手脚出疹才是手足口病。部分患儿仅出现口腔疱疹、发热咽痛,无手足皮疹,易被误诊,同样具有传染性,需及时排查。

误区二:患病一次即可终身免疫。常见的导致手足口病的肠道病毒有二十余种,感染一种仅对该型别免疫,儿童仍可能反复感染,需常年做好防护。

误区三:轻症无需就医。轻症可自愈,但若孩子出现持续高热、精神萎靡、肢体抖动、频繁呕吐等症状,属于重症前兆,需立即就医,切勿拖延。

总结

手足口病可防可控,无需过度紧张,但不可麻痹大意。病毒传播多源于日常细节疏漏,家校联动、做好手部防护、环境消杀、通风隔离、疫苗接种,坚守每一项防控细节,就能有效阻断肠道病毒传播,守护幼儿平安健康。

Incisionless vasectomy: puncture hole is completely blocked, reducing pain and recovery time

Chen Baozhong, a urologist at Fengyuan Hospital of the Ministry of Health and Welfare, pointed out that incisionless vasectomy completes the blockage of the vas deferens through a puncture hole of several millimeters, reducing skin incision and tissue stripping. Normal activities can be resumed the day after the operation, and sexual function will not be affected. However, contraception must be continued for 2 to 3 months after the operation and semen analysis must be performed to confirm azoospermia.

Kaohsiung City launches e-cigarette recycling mechanism with 43 locations for people to voluntarily recycle e-cigarettes to avoid penalties after amending the law

The Executive Yuan passed a draft amendment to some provisions of the Tobacco Harm Prevention Law, which will include the possession of e-cigarettes and other cigarette products as administrative penalties, and the fine will be increased to 30,000 to 100,000 yuan. The Kaohsiung City Health Bureau has set up 43 recycling points at the Health Bureau, District 38 Health Clinics and Community Health Centers since August to provide the public with the opportunity to actively recycle e-cigarettes to avoid being fined for possession after the new law is implemented. The recycling mechanism will continue until one month after the new law is passed and comes into effect.

"Ask" Health丨What is the difference between taking medicine "on an empty stomach, before meals, and after meals"? Pay attention to the timing of taking medicine

At the press conference of the National Health Commission, experts answered the question of when to take medicines: taking medicines on an empty stomach, before meals, and after meals have different effects. They emphasized the need to take medicines as directed by your doctor, warned that self-use of acid-suppressing medicines may bring health risks, and reminded that mood swings can easily cause gastrointestinal discomfort, and repeated episodes require medical treatment to rule out irritable bowel syndrome.

Migraines: Symptoms, Causes, and Management

Migraine is a genetic neurological disorder that affects more than 1 billion people worldwide, with women affected three times more often than men. Symptoms include headache, vomiting, dizziness and brain fog, and attacks are usually divided into four stages. Hormonal changes, irregular sleep, stress and weather changes are common triggers. Management methods include keeping a regular schedule, taking medications early, avoiding codeine, and considering treatments such as Botox and acupuncture. Experts recommend becoming a "migraine detective" to track personal triggers and maintain a regular lifestyle.
