        Although the name 'swine flu' brings up a lot of extra fear and worry, it is important to note that swine flu is just an influenza A H1N1 virus.

        That means that it is just another type of flu virus, just like that causes our typical seasonal flu symptoms. The big difference is that the current swine influenza A (H1N1) virus is new and most of us don't have any immunity to it. That is why it so easily became a pandemic virus (with the ability to cause a global outbreak), because it could easily spread from person to person.

        After a summer of declining flu cases, instances of swine flu began to rise again in early fall and there are now widespread swine flu cases in most of the US, as you can see on this swine flu map.

        Swine Flu Symptoms

        According to the CDC, like seasonal flu, symptoms of swine flu infections can include:

        fever, which is usually high, but unlike seasonal flu, is sometimes absent

        cough

        runny nose or stuffy nose

        sore throat

        body aches

        headache

        chills

        fatigue or tiredness, which can be extreme

        diarrhea and vomiting, sometimes, but more commonly seen than with seasonal flu

        Signs of a more serious swine flu infection might include pneumonia and respiratory failure.

        If your child has symptoms of swine flu, you should avoid other people and call your pediatrician who might do a rapid flu test to see if he has an influenza A infection. Further testing can then be done to see if it is a swine flu infection. (Samples can be sent to local and state health departments and the CDC for confirmation of swine flu, especially if a child is in the hospital.)

        Swine Flu High Risk Groups

        With regular seasonal flu, young children and the elderly are usually thought to be most at risk for serious infections, in addition to people with chronic medical problems. Swine flu high risk groups, people who are thought to be at risk for serious, life-threatening infections, are a little different and can include:

        pregnant women

        children under age two years old

        people with chronic medical problems, such as chronic lung disease, like asthma, cardiovascular disease, diabetes, and immunosuppression

        children and adults with obesity

        It is important to keep in mind that unlike seasonal flu, more than half of the hospitalizations and a quarter of the deaths from swine flu are in young people under the age of 25.

        Serious Swine Flu Symptoms

        More serious symptoms that would indicate that a child with swine flu would need urgent medical attention include:

        Fast breathing or trouble breathing

        Bluish or gray skin color

        Not drinking enough fluids

        Severe or persistent vomiting

        Not waking up or not interacting

        Being so irritable that the child does not want to be held

        Flu-like symptoms improve but then return with fever and worse cough

        Swine Flu Symptoms vs. a Cold or Sinus Infection

        It is important to keep in mind most children with a runny nose or cough will not have swine flu and will not have to see their pediatrician for swine flu testing.

        This time of year, many other childhood conditions are common, including:

        fall allergies - runny nose, congestion, and cough

        common cold - runny nose, cough, and low grade fever

        sinus infections - lingering runny nose, cough, and fever

        strep throat - sore throat, fever, and a positive strep test

        What You Need To Know

        Swine flu likely spreads by direct contact with respiratory secretions of someone that is sick with swine flu, like if they were coughing and sneezing close to you.

        People with swine flu are likely contagious for one day before and up to seven days after they began to get sick with swine flu symptoms.

        Droplets from a cough or sneeze can also contaminate surfaces, such as a doorknob, drinking glass, or kitchen counter, although these germs likely don't survive for more than a few hours.

        Anti-flu medications, including TamifluRelenza (zanamivir), are available to prevent and treat swine flu in high risk children.

        (oseltamivir) and

        The latest swine flu news from the CDC includes advice that daycare centers should do daily health checks, separate ill children until they can go home, encourage kids to stay home until they are free of fever for at least 24 hours, encourage proper hand-washing, and teach kids to properly cover their coughs and sneezes to help everyone avoid the flu.

        盡管"豬流感"這個(gè)名字帶來了許多額外的恐懼和憂慮,重要的是要注意,豬流感不過是一種甲型流行性感冒H1N1病毒。

        這就意味著它只是另一種類型的流感病毒,就像引起我們典型季節(jié)性流感癥狀的病毒那樣。最大的區(qū)別是,當(dāng)前的豬流感甲型(H1N1)病毒是新的,而我們大多數(shù)人對(duì)其沒有任何免疫力。這就是為什么它那么容易成為大規(guī)模流行病毒(具有引起全球爆發(fā)的能力)的原因,因?yàn)樗軌虿毁M(fèi)力地在人與人之間傳播。

        在夏天流感病例下降之后,初秋豬流感的病例開始再次上升。如同你可以在這張豬流感分布圖上看到的,現(xiàn)在美國(guó)的大部分都有廣泛分布的豬流感病例。

        豬流感的癥狀

        據(jù)疾病控制和預(yù)防中心的報(bào)告,像季節(jié)性流感那樣,豬流感感染的癥狀包括:

        * 發(fā)燒,通常是高燒,但是不像季節(jié)性流感,有時(shí)是不發(fā)燒的

        * 咳嗽

        * 流鼻涕或者鼻塞

        * 喉嚨痛

        * 身體疼痛

        * 頭痛

        * 發(fā)冷

        * 疲勞或者倦怠,可能極其嚴(yán)重

        * 腹瀉和嘔吐,有時(shí)出現(xiàn),但是比與季節(jié)性流感更常見

        更為嚴(yán)重的豬流感感染可能包括肺炎和呼吸衰竭。

        如果你的孩子有豬流感癥狀,應(yīng)該避免和別人接觸并且去瞧兒科醫(yī)師,他可能做一個(gè)快速的流感測(cè)試,以分辨你的孩子是否受到甲型流感病毒的感染。然后可以做進(jìn)一步的測(cè)試,看看是不是豬流感感染。(樣品可以送往當(dāng)?shù)氐暮椭萘⒌男l(wèi)生部門以及美國(guó)疾病控制與預(yù)防中心,用來確認(rèn)豬流感,特別是如果孩子正在住院時(shí)。)

        豬流感的高危人群

        對(duì)于常規(guī)季節(jié)性流感來說,兒童和老年人通常被認(rèn)為是最具有嚴(yán)重感染風(fēng)險(xiǎn)的,此外是對(duì)于具有慢性醫(yī)療問題的人。豬流感的高危人群,那些被認(rèn)為處于嚴(yán)重的、威脅生命的感染危險(xiǎn)的人有點(diǎn)不同,可能包括:

        * 孕婦

        * 2 歲以下的兒童

        * 具有慢性醫(yī)療問題的人,例如慢性肺部疾病,像哮喘、心血管疾病、糖尿病以及免疫抑制等

        * 具有肥胖癥的兒童和成人

        重要的是要記住,與季節(jié)性流感不同,一半以上的住院者和四分之一由于豬流感死亡的人數(shù)是年齡25歲以下的年輕人。

        嚴(yán)重豬流感的癥狀

        更為嚴(yán)重的癥狀,可能表明一個(gè)患豬流感的孩子需要緊急醫(yī)療照顧,包括:

        * 快速呼吸或者呼吸困難

        * 藍(lán)色或者灰色膚色

        * 不喝足夠的流體

        * 嚴(yán)重的或者持續(xù)性的嘔吐

        * 不醒或者沒有互動(dòng)

        * 變得急躁易怒,以致孩子都不愿被抱起

        * 流感樣癥狀改善,但是然后轉(zhuǎn)為發(fā)燒和糟糕的咳嗽

        豬流感癥狀與感冒或者鼻竇感染的比較

        這是很重要的,要記住大多數(shù)流鼻涕或者咳嗽的孩子并不是患豬流感,不需要去瞧他們的兒科醫(yī)師進(jìn)行豬流感的測(cè)試。

        每年這個(gè)時(shí)候,很多其它的兒童情況是普遍的,包括:

        * 秋天過敏癥--流鼻涕、充血以及咳嗽

        * 普通感冒--流鼻涕、咳嗽以及發(fā)低燒

        * 鼻竇感染--連綿地流鼻涕,咳嗽以及發(fā)燒

        * 膿毒性咽喉炎--喉嚨痛、發(fā)燒以及鏈狀球菌感染測(cè)試陽性

        你需要知道的事情

        * 豬流感可能通過直接接觸某人的呼吸道分泌物而傳播,該人患豬流感病,可能是在他們接近你咳嗽和打噴嚏的時(shí)候。

        * 患豬流感的人很可能在開始生病具有豬流感癥狀的前一天,直到開始具有豬流感癥狀之后的第七天,具有傳染性。

        * 咳嗽或者打噴嚏的飛沫也可能污染比如門把手、水杯或者廚房柜臺(tái)的表面,雖然這些細(xì)菌可能不能超過幾小時(shí)存活。

        * 抗流行性感冒的藥物。包括達(dá)菲(oseltamivir)和瑞樂沙(zanamivir),可用來在高危兒童中預(yù)防和治療豬流感。

        * 來自疾病控制與預(yù)防中心的最新的豬流感消息,包括建議日托中心應(yīng)該進(jìn)行每天的健康檢查,分開生病的孩子直到他們能回家時(shí),鼓勵(lì)孩子們呆在家里直到他們至少24小時(shí)不再發(fā)燒,鼓勵(lì)正確的洗手,以及教導(dǎo)孩子們適當(dāng)?shù)負(fù)踝∷麄兛人院痛驀娞鐏韼椭蠹冶苊饬鞲小?/p>
