HBV是指乙型肝炎病毒。HBV是hepatitisBvirus的英文缩写,hepatitis的英文意思是肝炎的意思。B是乙型,virus的英文意思是病毒。HBV在正常免疫功能的感染者引起急性病变;在异常免疫功能者则发生慢性肝炎和慢性肝病。HBV不是致细胞病变性(cytopathogenic)病毒,HBV感染后须经宿主的免疫应答引起病变,并使疾病进展。
早期肝炎症状表现如下:
一、疲乏无力。这是肝炎病人发病的早期表现之一。
二、食欲减退,恶心厌油。这是大多数肝炎病人都有的症状,尤其是黄疽型肝炎病人表现更严重。
三、发热。急性黄疽型肝炎早期常有发热,多在37.5-38.5摄氏度,高热者少见,一般持续3-5天,而无黄疽型肝炎者发热远远低于黄疽型肝炎者。
四、出现肝区隐痛、肝区肿涨;肝炎病人常常诉说肝区痛,涉及右上腹或右背部,疼痛程度不一,有的胀痛、钝痛或针刺样痛,活动时加剧,且时间不一;有时左侧卧位时疼痛减轻。
五、巩膜或皮肤黄染,或出现“三黄”症状。黄疸型肝炎病人都有尿黄的症状。初起尿色淡黄,逐日加深,浓如茶色或豆油状,继而皮肤及巩膜发黄。
拓展资料:
乙型病毒性肝炎(viral hepatitis type B,简称乙肝)系由乙肝病毒(HBV)引起,以乏力、食欲减退、恶心、呕吐、厌油、肝大及肝功能异常为主要临床表现。部分病例有发热和黄疸;少数病例病程迁延转为慢性,或发展为肝硬化甚至肝癌;重者病情进展迅猛可发展为重型肝炎;另一些感染者则成为无症状的病毒携带者。

Grape species of Micrococcus Branch, the existing 19 species, from a human body on the detection of 12 species, such as Staphylococcus aureus (S. aureus), Staphylococcus epidermidis, Staphylococcus aureus and other saprophytic. Staphylococcal enterotoxins have the two: Staphylococcus aureus and Staphylococcus epidermidis. Generally considered a coagulase-pathogenic Staphylococcus aureus is a good indicator, although with Staphylococcus epidermidis pathogenicity, but coagulase-negative. Staphylococcus aureus mainly exists in the skin and mucous membrane, in particular the nasopharynx. 30% of a 80 per cent of the population of pathogenic bacteria carriers, is a 2 and 1 is carried by the carriers for producing strains of pathogens [ ']. Therefore, Staphylococcus aureus greater probability of contamination of foodstuffs, food producers and skin damage asymptomatic carriers often become food sources. Staphylococcus aureus in the water, protein and starch in food more easily breed and produce toxins. Food poisoning is more than animal food, milk and dairy products, residual rice, jelly, milk hygiene carrier rate up to 76.3 percent. According to Japanese scholars of the survey showed that an average of 32.5 per cent of the food there Staphylococcus aureus pollution [ ']. Food poisoning caused by Staphylococcus aureus is the main reason for eating with Staphylococcus aureus enterotoxin food. At present, the enterovirus serotype toxin can be divided into 14 (A, B, e, D, E, e, H, I, J, K, L, M, N, o)-chuan, an outbreak of food poisoning in the most For the common serotype A and Type D, B and c-times, of which the A-type virulence of the most closed. According to a report containing a nursing an loscfiJ "g (MDR), Staphylococcus aureus can be effective in causing food poisoning symptoms of intestinal toxins. Contaminated food were usually a fresh six hours of a food poisoning can occur. Staphylococcus aureus bacteria in food poisoning caused by food poisoning in a large percentage. In many countries Staphylococcus aureus is considered an outbreak of food poisoning caused the second and third pathogens [ ']. U.S. Centre for Disease Control and Prevention (CentersforDiseaseConti persuade 1 andRrevention, CDC) report, the food poisoning caused by Staphylococcus aureus bacterial food poisoning accounted for the entire 33 per cent, 45 per cent of Canada, some European countries such as Hungary and Finland, accounting for more than 50% . Food poisoning caused by bacteria from the typical number of incidents is also not see fresh. The U.S. Food and Drug Administration (where Hutchison andDrugA Hill ministlution, that is, A) "BadBugB00k" in a typical incident was reported in the U.S. state of Texas because of the Staphylococcus aureus Blue cheese dressing salad pollution caused by food poisoning, food poisoning from the lead to 16 primary schools of 5,824 students in 1,364 patients.

International food microbiology specifications Committee (Intemation public CommissiononMierobiologi-c spit Spec Xun cationsforFoods, ICMSF) of Staphylococcus aureus have been carried out to assess the degree of harm, will be classified as moderate its direct local spread of pathogens. Japan's Koji positions through the National Statistics of food poisoning mortality, morbidity and with the average number of the incidence of S. aureus to assess the degree of harm, its results and recommendations of harm ICMSF coefficient consistent. In view of the danger of Staphylococcus aureus itself and its cause serious food poisoning incidents, the Food and Staphylococcus aureus in the test is very necessary!

Dear Lihua,
I’m glad to receive your email.You asked me to share with you what I’m doing in the epidemic situation.Here are my experiences.
Since the outbreak of novel coronavirus pneumonia in Wuhan in December,2019,I have been staying at home.On the one hand,I pay close attention to the epidemic situation through watching CCTV news or surfing the Internet;on the other hand I insist on studying.
Not only do I read classics, but also I have online courses given by my teachers.Besides,I take exercise every day to keep healthy.Faced with the disaster,many people including doctors,nurses and scientists act bravely and spare no effort to fight against it.They are real heroes.
Thank you for your concern.I’m looking forward to your reply.

Four caused relatively mild cold-like symptoms while the other two, Sars and Middle East respiratory syndrome (Mers), can be fatal.此次疫情爆发之前,已知的人类冠状病毒有6种。四种引起相对轻度的类似感冒症状,而另外两种——非典和中东呼吸综合征(MERS)——可能致命。 2、“新型冠状病毒“英文怎么说?“新型冠状病毒”的英文是 novel coronavirus这里的 novel 不是“小说”而是一个形容词,表示“新型的”比如 a novel feature(新特性) 3、其他常用词汇解析①fatal /ˈfeɪtl / :a. 致命的;毁灭性的;灾难性的 (对于目前的状况来看,这的确是很丧的一个词儿!)②infectious disease/ ɪnˈfekʃəs dɪˈziːz / :传染病infectious /ɪnˈfekʃəs /:a.传染的 由 infect (v. 传染;感染)+ ious(形容词后缀)构成infect / ɪnˈfekt /:v. 传染;感染 由 in (进入,使。。。)+ fect (做) 构成 ——咱可以想一下儿:传染或感染,不正是有害物质或病毒,侵入体内,对健康的肌体做坏事儿——进行破坏吗?infection / ɪnˈfekʃn /:n. 传染 由 infect + -ion (名词后缀)构成③pneumonia / nuˈmoʊnɪə / n. 肺炎这个词,是由 pneumon- (肺)+ -ia (疾病名词后缀)构成 4、冠状病毒的传播途径①the air by coughing and sneezing经由空气传播,比如咳嗽、打喷嚏②close personal contact, such as touching or shaking hands通过人与人之间的近距离接触传播,比如触摸或者握手③touching an object or surface with the virus>通过触摸物品或感染病毒的用品表面传播,原因在于没洗手就触摸嘴、鼻和眼睛④rarely, fecal contamination还有一种比较少见的,就是通过粪便传染5、如何预防“冠状病毒”① Clean hands with soap and water or alcohol-based hand rub.用肥皂或者用含酒精的洗手液洗手。②Cover nose and mouth when coughing and sneezing with tissue or flexed elbow.咳嗽或打喷嚏时,用面巾纸或屈肘捂住口鼻。③Avoid close contact with anyone with cold or flu-like symptoms.避免跟有感冒或流感症状的人密切接触。④ Thoroughly cook meat and eggs.将肉类和鸡蛋彻底煮熟。⑤Avoid unprotected contact with live wild or farm animals.避免在未加防护的情况下接触野生动物或家畜。
