被感染了猪流感的猪有何症状？

猪流感是一种由甲型流感病毒（H1N1亚型）感染猪只引起的呼吸道疾病。虽然猪流感通常只会在猪群中传播，但在某些情况下，它也可以感染人类。了解猪流感的症状对于预防和控制这种疾病非常重要。下面是被感染了猪流感的猪的常见症状：

1. 咳嗽和打喷嚏：感染猪流感的猪会出现咳嗽和打喷嚏的症状。这种咳嗽通常是干咳，而且会持续一段时间。

2. 呼吸困难：猪流感会导致猪只呼吸困难，表现为急促的呼吸和气喘。猪只会感到气短，并且呼吸声变得明显。

3. 胃肠道症状：被感染了猪流感的猪可能会出现食欲下降、呕吐和腹泻等胃肠道症状。这些症状通常与呼吸道症状同时出现。

4. 活动能力下降：感染猪流感的猪可能会感到乏力和活动能力下降。它们可能会变得迟钝，不愿意活动或者只能进行有限的运动。

5. 发热：猪流感会引起猪只的发热。猪体温升高，通常超过正常体温。

6. 眼部症状：有些被感染了猪流感的猪可能会出现眼部症状，如发红、流泪和眼结膜充血等。

需要注意的是，猪流感的症状可以因猪只的年龄、健康状况和感染程度而有所不同。年幼的猪只和免疫力较弱的猪只往往会表现出更严重的症状。此外，猪流感也可能与其他疾病的症状相似，因此确诊需要进行病毒检测。

了解猪流感的症状是预防和控制这种疾病的关键。如果发现猪只出现上述症状，应尽快与兽医联系以获得适当的治疗和控制措施。

What are the symptoms of pigs infected with swine flu?

Swine flu is a respiratory disease caused by the infection of pigs with the influenza A virus (subtype H1N1). Although swine flu usually only spreads within pig populations, it can also infect humans in certain cases. Understanding the symptoms of swine flu is crucial for preventing and controlling this disease. Here are the common symptoms of pigs infected with swine flu:

1. Coughing and sneezing: Pigs infected with swine flu will exhibit symptoms of coughing and sneezing. This cough is usually dry and can last for a period of time.

2. Difficulty breathing: Swine flu can cause difficulty breathing in pigs, manifested as rapid breathing and wheezing. Pigs may feel short of breath, and their breathing sounds become noticeable.

3. Gastrointestinal symptoms: Pigs infected with swine flu may experience a decrease in appetite, vomiting, and diarrhea. These symptoms often occur simultaneously with respiratory symptoms.

4. Decreased activity: Pigs infected with swine flu may feel lethargic and have decreased activity. They may become sluggish, reluctant to move, or only capable of limited movement.

5. Fever: Swine flu can cause fever in pigs. The body temperature of pigs rises, often exceeding the normal range.

6. Ocular symptoms: Some pigs infected with swine flu may exhibit ocular symptoms such as redness, tearing, and conjunctival congestion.

It is important to note that the symptoms of swine flu can vary depending on the age, health condition, and degree of infection in pigs. Younger pigs and those with weaker immune systems tend to show more severe symptoms. Additionally, swine flu may also have symptoms similar to other diseases, so a viral test is necessary for diagnosis.

Understanding the symptoms of swine flu is key to preventing and controlling this disease. If any of the above symptoms are observed in pigs, it is important to contact a veterinarian promptly for appropriate treatment and control measures.

　　How does swine flu spread among pigs?

　　Swine flu viruses are thought to be spread mostly through close contact among pigs and possibly from contaminated objects moving between infected and uninfected pigs. Herds with continuous swine flu infections and herds that are vaccinated against swine flu may have sporadic disease, or may show only mild or no symptoms of infection.

　　猪流感在猪群中如何传播？

　　猪流感病毒被认为通过猪之间的近距离接触进行传播，另一种可能的传播方式是携带病毒的物体将病毒从被感染的猪群传播到健康的猪群中。被连续感染猪流感的猪，以及已注射抗流感疫苗的猪会零星地发生流感，或者只出现轻微的感染症状，或者会不出现感染。

　　What are signs of swine flu in pigs?

　　Signs of swine flu in pigs can include sudden onset of fever, depression, coughing (barking), discharge from the nose or eyes, sneezing, breathing difficulties, eye redness or inflammation, and going off feed.

　　被感染了猪流感的猪有何症状？

　　症状包括突发的发烧，抑郁，咳嗽(吠叫)，鼻子或者眼睛产生排泄物，打喷嚏，呼吸困难，眼红或者眼肿，以及厌食。

　　How common is swine flu among pigs?

　　H1N1 and H3N2 swine flu viruses are endemic among pig populations in the United States and something that the industry deals with routinely. Outbreaks among pigs normally occur in colder weather months (late fall and winter) and sometimes with the introduction of new pigs into susceptible herds. Studies have shown that the swine flu H1N1 is common throughout pig populations worldwide, with 25 percent of animals showing antibody evidence of infection. In the U.S. studies have shown that 30 percent of the pig population has antibody evidence of having had H1N1 infection. More specifically, 51 percent of pigs in the north-central U.S. have been shown to have antibody evidence of infection with swine H1N1. Human infections with swine flu H1N1 viruses are rare. There is currently no way to differentiate antibody produced in response to flu vaccination in pigs from antibody made in response to pig infections with swine H1N1 influenza.

　　While H1N1 swine viruses have been known to circulate among pig populations since at least 1930, H3N2 influenza viruses did not begin circulating among US pigs until 1998. The H3N2 viruses initially were introduced into the pig population from humans. The current swine flu H3N2 viruses are closely related to human H3N2 viruses.

　　猪流感在猪群中经常发生吗？

　　H1N1和H3N2猪流感病毒在美国是地区性发作的`，这也是养猪业经常要面对的问题。流感通常在天气寒冷的月份爆发（深秋以及冬季），并且会从猪传播到其他易感染的牲畜当中。研究表明H1N1猪流感在全世界猪群中都比较普遍，并且抗体证据表明有25%的动物被感染过。在美国，有30%的猪被检测出抗体，表明它们被H1N1感染过，而在美国中北部，这个比例是51%。人类感染H1N1猪流感病毒的病例很少见。比较接种猪流感疫苗而产生的抗体与猪抵抗H1N1病毒而产生的抗体，两者到目前为止并没有发现不同之处。

　　H1N1猪流感病毒早在1930年就被发现在猪群中传播，而H3N2流感病毒则直到1998年才发现在美国传播开来。H3N2病毒一开始是从人身上传染到猪的，现在的H3N2猪流感病毒与H3N2人流感病毒有着很近的相关性。

　　Is there a vaccine for swine flu?

　　Vaccines are available to be given to pigs to prevent swine influenza. There is no vaccine to protect humans from swine flu. The seasonal influenza vaccine will likely help provide partial protection agai

　　猪流感有疫苗吗？

　　猪流感疫苗被用于防止猪流感在猪群中传播，但目前没有疫苗来防止猪流感在人群中传播。对人来说，季节性流感疫苗很可能只能提供部分的保护免受H3N2猪流感病毒，但对于H1N1猪流感病毒，该疫苗没有保护作用。
