【预期用途】 
基孔肯雅IgG/IgM抗体ELISA检测试剂盒主要用于定性检测人血清和血浆中抗基孔肯雅病毒的IgG
/IgM抗体。 
【实验原理】 
此试剂盒基于ELISA技术。包被板中包被了抗人IgG抗体,如果人血清或血浆中含有IgG时,则会与其特异性结合,洗板将未结合的物质洗去, 然后加入基孔肯雅抗原溶液,洗板洗去未结合的物质,然后加入链霉亲和素和基孔肯雅抗体酶联物。洗板后,加入TMB底物液,颜色变成蓝色,加入终止液终止反应,颜色由蓝色转为黄色,zui后用酶标仪在450nm处读数。 
【试剂组成】 
包被板:12×8可拆卸,包被了抗人IgG抗体,密封在可重封铝箔袋中 
基孔肯雅溶液1:1瓶包含6mL的基孔肯雅抗原溶液,即用,白盖 
基孔肯雅溶液2:1瓶包含6mL的生物素化的基孔肯雅抗体,即用,蓝色,白盖 
基孔肯雅IgM阳性质控:1瓶,1.5mL,黄色,即用,红盖 
基孔肯雅IgM临界质控:1瓶, 2mL,黄色,即用,绿盖

【需要的设备和材料】              
固定板
封板片 
酶标仪(450/620nm)              
37℃孵箱 
洗瓶或自动洗板机
10~1000μL的移液器
漩涡混匀器 
蒸馏水或去离子水
一次性试管
计时器 
【储存和稳定性】 
试剂在有效期内,储存于2-8℃稳定 
【试剂准备】 
洗涤液的准备 
用双蒸水稀释洗涤液,例子:10ml洗涤液+190ml双蒸水。稀释好的洗涤液在室温下5天内有效。 
【样本的采集和准备】 
这个实验中使用的样本是人血清和血浆,如果实验在样本采集后的5天内进行,则需要储存在2-8℃,否则,必须于-20℃到-70℃深度冻存。如果样本是深度冻存的,在使用前,则需要充分混匀,避免反复冻融。 不推荐使用热灭活的样本 
【样本的稀释】 
将10μL样本跟1ml的样本稀释液混匀,并用漩涡混匀器充分混匀。
【实验步骤】 
在开始试验前,请仔细阅读试验说明。结果的可信度是依赖于严格地按照实验说明来进行的,铺板时zui少留1个孔为空白对照(A1)1个阴性质控孔(B1)2个临界质控孔(C1+D1)1个阳性质控孔(E1)。开始试验前,请将所有试剂都平衡到室温 
1.  吸取50μL的质控品和稀释过的样本到相应的孔中,留A1孔做空白对照孔
2.  封板 
3.  在37±1℃下孵育1小时±5分钟 
4.  当孵育完成时,揭去封板片,弃去反应液,每孔300μL洗涤液,洗板3次,避免溢出。每孔浸泡的时间都必须>5秒,zui后拍板将残留的液滴都拍去。 
5.  吸取50μL基孔肯雅溶液1到除了空白对照孔的每个孔中,盖板 
6.  在室温孵育30分钟 
7.  重复步骤4 
8.  将基孔肯雅溶液2跟链霉亲和素结合物混匀10分钟 
9.  吸取50μL基孔肯雅溶液2跟链霉亲和素的复合物到除了空白对照孔的每个孔中,盖板。 
10.  室温孵育30分钟
11.  重复步骤4 
12.  吸取100μL的TMB底物液到每个孔中 
13.  避光孵育15分钟(精确) 
14.  加入100μL终止液到每个孔中,与加TMB底物液时的间隔和顺序都必须一样 
15.  用酶标仪在加入终止液后30分钟内与450/620nm处检测 
【检测】 
调整酶标仪,以空白对照孔调零,以450nm处检测所有孔的吸光度值。 
【结果】 
1.  检测生效的条件 
只有以下条件符合,检测的结果才能认为的有效的  
空白对照孔    吸光度值<0.100  
阴性质控孔    吸光度值<临界质控  
临界质控孔    吸光度值0.150-1.300  
阳性质控孔    吸光度值>临界质控 
如果以上条件不符合的,那么试验结果则是无效的,需要重新检测
2.  结果的计算 
临界质控平均吸光度值的计算,例子:吸光度1:0.39;吸光度2:0.37                                   
(0.39+0.37)/2=0.38    
平均吸光度值为0.38 
3.  结果的说明 
样本如果是比临界值高出10%,则认定为阳性, 
样本如果是在临界值上下10%之内,则认定为灰色区(推荐在2-4周之后再次检测新鲜的样本,如果样本仍然是灰色区,可以直接认为是阴性) 
样本如果是比临界值低出10%,则认定为阴性 
4.  结果的单位 
病人样本平均吸光度值×10 = U   
临界值 
例子: 1.216×10 =32U 
0.38 
临界值: 10 U 
灰色区:9-11 U 
阴性: <9 U 
阳性: >11 U

病例管理和病例搜索
基孔肯雅蚊症1950年代在非洲坦桑尼亚*记载
基孔肯雅蚊症1950年代在非洲坦桑尼亚*记载基孔肯雅热
各级医疗机构发现疑似基孔肯雅热病例后要及时报告,使卫生行政部门和疾病预防控制机构尽早掌握疫情并采取必要的防控措施。医院对处在病毒血症期的病人(发病后4天内)应采取蚊帐或驱蚊剂等措施防止蚊虫叮咬,病房内采用杀蚊剂杀灭成蚊,以防止病毒传播。
疾控人员接到病例报告后要立即进行流行病学调查,包括调查疑似病例在发病期间的活动史、调查接触者和共同暴露者、寻找感染来源和可疑的感染地点,搜索病例发病前2周和发病后5天内居留地点的漏报和漏诊病例,以指导疫点的紧急喷药、清除孳生地等后续工作。
媒介应急监测和控制
 (1)蚊媒应急监测
疫情发生后,由县级疾病预防控制中心负责在疫区内,重点是疫点及周围地区开展蚊媒应急监测,调查疫区内50~100户居民,检查室内外所有积水容器及蚊幼虫孳生情况,计算布雷图指数、容器指数,每3天进行一次。同时,捕捉伊蚊成蚊分离病毒,鉴定型别。及时根据媒介监测及控制情况,评估疫情扩散的风险。
(2)媒介控制
发生暴发疫情时,要针对不同蚊种、当地孳生地特点尽快采取灭蚊和清除蚊虫孳生地等措施,以降低成蚊或蚊幼虫密度。特别要做好流行区内医院、学校、机关、建筑工地等范围内的灭蚊工作。
(1)紧急喷药,杀灭成蚊。根据病例调查资料,针对病例可能传播给他人的地点,立即紧急喷药杀灭成蚊,间隔一周再次喷药,共喷药三次。
(2)清除伊蚊孳生地。在疫点周围半径100米范围内开展清除伊蚊孳生地工作。根据疾病传播风险的评估结果,结合蚊媒监测情况,在更大范围内开展紧急蚊媒控制工作。
开展灭蚊工作后,要对媒介控制效果进行评估。当疫情得到有效控制,在1个月内无新发病例,以及布雷图指数和诱蚊诱卵指数降到5以下时,可结束本次应急处理工作。
社区动员和健康教育
发生本地暴发疫情时,要立即开展广泛深入的宣传和社区动员,发动社区和广大群众,开展爱国卫生运动,整治环境和清除蚊虫孳生地。

深圳口岸*检出/基孔肯雅热 基孔肯雅热
深圳检验检疫局2009年11月21日对外通报,该局日前在宝安机场口岸检出深圳*输入性“基孔肯雅热”患者。据了解,该男性旅客来自上海,入境前一周在马来西亚出差,其血样于11月19日确认“基孔肯雅病毒核酸”呈阳性。深圳检疫部门已经通报上海的卫生部门共同做好防控工作。患者已被转诊。基孔肯雅热
爆发疫情/基孔肯雅热 基孔肯雅热
2010年10月1日,东莞市报告万江新村社区发现基孔肯雅热疑似病例。10月2日,省疾病预防控制中心在东莞市送检的15例发热病例血标本中检测到10例基孔肯雅热病毒核酸阳性。根据病例的临床特征、流行病学调查及实验室检测结果,认定为一起基孔肯雅热社区聚集性疫情。经流行病学调查,截至10月1日,共发现91例疑似病例。病例均为轻症病例,以发热并伴有关节痛、肌肉骨骼痛或皮疹症状为主,绝大多数已经*,无住院、重症和死亡病例。基孔肯雅热
2013年9月,据澳大利亚“新快网”报道,不少从巴厘岛等亚洲景点旅游回国的澳大利亚游客都感染了基孔肯雅病毒。报道称,2013年头9个月里,感染这种病毒的澳人增加至创纪录的107人,而2011年同期才37人,2012年仅19人。
基孔肯雅热(chikungunya fever)是由基孔肯雅病毒(chikungunya virus, CHIKV)引起,经伊蚊传播,以发热、皮疹及关节疼痛为主要特征的急性传染病。1952年*在坦桑尼亚证实了基孔肯雅热流行,1956年分离到病毒。本病主要流行于非洲和东南亚地区,近年在印度洋地区造成了大规模流行。

As long as the chikungunya epidemic continues, travelers may become infected and spread the virus. The mosquitoes that can transmit chikungunya virus are common in many parts of the Americas, including parts of the United States. In these locations, travelers infected with chikungunya virus may be bitten by mosquitoes after returning home, which can lead to local cases or outbreaks.
Click here for information on countries where chikungunya has been found.
Click here to see the latest number of cases in the United States.
Should we be concerned about chikungunya virus in the United States?
Yes. Each year, millions of travelers visit countries where chikungunya outbreaks are ongoing. People become infected through mosquito bites. The two types of mosquitoes that can spread chikungunya virus – Aedes aegypti and Aedes albopictus – are found in parts of the U.S.[PDF – 292 KB] so it is possible for the virus to spread here once imported.
Infected travelers bring chikungunya virus into the U.S. every year. From 2006?2013, an average of 28 people per year had confirmed cases of chikungunya. All were travelers visiting or returning to the United States from affected areas, mostly in Asia. None of those imported cases resulted in locally-acquired cases or an outbreak.
However, more chikungunya-infected travelers will come into the U.S. from the Americas, increasing the likelihood that limited local chikungunya virus transmission could occur. Since the Caribbean outbreak began in December, 2013, over 750 travelers have returned to the U.S. infected with chikungunya virus. And as of August 2013, a handful of locally acquired cases had been reported in the continental U.S. It is important for public health experts and healthcare providers to be aware of chikungunya in patients with a recent travel history and to test for and report cases.
Are there things that I and my community can do to prevent local transmission or an outbreak of chikungunya?
Yes. There are a variety of things you can do to protect yourself and your community from chikungunya. Because there is no vaccine to prevent or medicine to treat the infection, follow these guidelines to protect yourself from infection with chikungunya virus and other mosquito-borne diseases, like West Nile virus:
Prevent mosquito bites: cover up and wear insect repellent
The mosquitoes that spread chikungunya virus are aggressive day-time biters. This means you need to protect yourself from bites anytime you are outside during the daytime hours if you are in an area where chikungunya virus has been found.
Cover exposed skin by wearing long-sleeved shirts, long pants, and hats.
Use an appropriate insect repellent as directed.
Higher percentages of active ingredient provide longer protection. CDC recommends products with the following active ingredients:
DEET (Products containing DEET include Off!, Cutter, Sawyer, and Ultrathon)
Picaridin (also known as KBR 3023, Bayrepel, and icaridin products containing picaridin include Cutter Advanced, Skin So Soft Bug Guard Plus, and Autan [outside the US])
Oil of lemon eucalyptus (OLE) or PMD (Products containing OLE include Repel and Off! Botanicals)
IR3535 (Products containing IR3535 include Skin So Soft Bug Guard Plus Expedition and SkinSmart)

If you are sick[PDF – 693 KB], protect yourself and others from mosquito bites during the first week of illness.
During the first week of illness, virus can be found in your blood.
The virus can be passed from an infected person to a mosquito if the mosquito bites the person during the first week when they are infectious.
An infected mosquito can then transmit the virus to other people.
Support your local and state public health department’s mosquito control activities.
In the United States, mosquito control activities are funded at the local and state level. During an outbreak, aggressive mosquito management can help reduce the likelihood of further spread of the virus.

Chikungunya
J. Erin Staples, Susan L. Hills, Ann M. Powers

INFECTIOUS AGENT
Chikungunya virus is a single-stranded RNA virus that belongs to the family Togaviridae, genus Alphavirus.

TRANSMISSION
Chikungunya virus is transmitted to humans via the bite of an infected mosquito of the Aedes spp., predominantly Aedes aegypti and Ae. albopictus. Nonhuman and human primates are likely the main reservoirs of the virus, and human-to-vectorto-human transmission occurs during outbreaks of the disease. Bloodborne transmission is possible; 1 case was documented in a health care worker who was stuck with a needle after drawing blood from an infected patient. Cases have also been documented among laboratory personnel handling infected blood and through aerosol exposure in the laboratory.
The risk of a person transmitting the virus to a biting mosquito or through blood is highest when the patient is viremic, usually during the first 2–6 days of illness. Maternal-fetal transmission has been documented during pregnancy; the highest risk occurs when a woman is viremic at the time of delivery. Studies have not found virus in breast milk.
