Chinkungunya (চিকুনগুনিয়া রোগের লক্ষন ও চিকিৎসা) বাংলা Apps>>>>>>>>>>>>>> Chikungunya is an infection caused by the chikungunya virus (CHIKV).[3] Symptoms include fever and joint pain.[2] These typically occur two to twelve days after exposure.[3] Other symptoms may include headache, muscle pain, joint swelling, and a rash. Most people are better within a week; however, occasionally the joint pain may last for months.[2] The risk of death is around 1 in 1,000.[4] The very young, old, and those with other health problems are at risk of more severe disease.[2] The virus is spread between people by two types of mosquitos: Aedes albopictus and Aedes aegypti.[3] They mainly bite during the day.[5] The virus may circulate within a number of animals including birds and rodents. Diagnosis is by either testing the blood for the virus's RNA or antibodies to the virus. The symptoms can be mistaken for those of dengue fever and Zika fever.[3] After a single infection it is believed most people become immune.[2][2] The best means of prevention is overall mosquito control and the avoidance of bites in areas where the disease is common.[4] This may be partly achieved by decreasing mosquitoes' access to water and with the use of insect repellent and mosquito nets. There is no vaccine and no specific treatment as of 2016.[3] Recommendations include rest, fluids, and medications to help with fever and joint pain.[3][2] While the disease typically occurs in Africa and Asia, outbreaks have been reported in Europe and the Americas since the 2000s. In 2014 more than a million suspected cases occurred.[3] In 2014 it was occurring in Florida in the continental United States but as of 2016 there was no further locally acquired cases.[6][7] The disease was first identified in 1952 in Tanzania.[3] The term is from the Kimakonde language and means "to become contorted" The incubation period of the chikungunya virus ranges from one to twelve days, and is most typically three to seven.[8] The disease may be asymptomatic, but generally is not, as 72% to 97% of those infected will develop symptoms.[8] Characteristic symptoms include sudden onset with high fever, joint pain, and rash. Other symptoms may occur, including headache, fatigue, digestive complaints, and conjunctivitis.[9] Information gained during recent epidemics suggests that chikungunya fever may result in a chronic phase as well as the phase of acute illness.[10] Within the acute phase, two stages have been identified: a viral stage during the first five to seven days, during which viremia occurs,[11] followed by a convalescent stage lasting approximately ten days, during which symptoms improve and the virus cannot be detected in the blood.[8] Typically, the disease begins with a sudden high fever that lasts from a few days to a week, and sometimes up to ten days. The fever is usually above 39 °C (102 °F) and sometimes reaching 40 °C (104 °F) and may be biphasic—lasting several days, breaking, and then returning. Fever occurs with the onset of viremia, and the level of virus in the blood correlates with the intensity of symptoms in the acute phase.[11] When IgM, an antibody that is a response to the initial exposure to an antigen, appears in the blood, viremia begins to diminish. However, headache, insomnia and an extreme degree of exhaustion remain, usually about five to seven days.[12] Following the fever, strong joint pain or stiffness occurs; it usually lasts weeks or months, but may last for years. The joint pain can be debilitating, often resulting in near immobility of the affected joints.[13] Joint pain is reported in 87–98% of cases, and nearly always occurs in more than one joint, though joint swelling is uncommon.[8] Typically the affected joints are located in both arms and legs, and are affected symmetrically. Joints are more likely to be affected if they have previously been damaged by disorders such as arthritis.[10] Pain most commonly occurs in peripheral joints. Thanks
