Symptoms | Chikungunya virus | CDC - 0 views

  • Symptoms, Diagnosis, & Treatment Symptoms Most people infected with chikungunya virus will develop some symptoms. Symptoms usually begin 3–7 days after being bitten by an infected mosquito. The most common symptoms are fever and joint pain. Other symptoms may include headache, muscle pain, joint swelling, or rash. Chikungunya disease does not often result in death, but the symptoms can be severe and disabling. Most patients feel better within a week. In some people, the joint pain may persist for months. People at risk for more severe disease include newborns infected around the time of birth, older adults (≥65 years), and people with medical conditions such as high blood pressure, diabetes, or heart disease. Once a person has been infected, he or she is likely to be protected from future infections. Diagnosis The symptoms of chikungunya are similar to those of dengue, another disease spread by mosquitoes. See your doctor if you develop the symptoms described above. If you have recently traveled, tell your doctor. Your doctor may order blood tests to look for chikungunya or other similar diseases. Treatment There is no medicine to treat chikungunya virus infection or disease. Decrease the symptoms: Get plenty of rest Drink fluids to prevent dehydration Take medicines, such as ibuprofen, naproxen, acetaminophen, or paracetamol, to relieve fever and pain.

      how is it spread: touch people infected by wave the hand of the person infected.
  • Humans and other primates are the natural hosts for the chikungunya virus. The virus is spread to humans by the bite of an infected female Aedes species mosquito – Aedes aegypti or Aedes albopictus. These are the same tropical and sub-tropical mosquitoes that carry the dengue virus. They breed in or near human habitations and prefer to feed on humans during the daytime in shady areas, but may also bite early in the night. In Australia, Aedes aegypti currently is found in north Queensland while Aedes albopictus is found in a few locations in the Torres Strait. Infections reported in Australia are from people who have travelled overseas to regions where the chikungunya virus is present. To date chikungunya virus infection has not been transmitted by mosquitoes in Australia. However, since the mosquitoes capable of transmitting the infection are found in northern Australia there is the potential for this to occur.

Chikungunya - Wikipedia, the free encyclopedia - 0 views

  • The incubation period of chikungunya disease ranges from 2 to 12 days, typically two to three. The majority of those infected will develop symptoms.[11] Symptoms include a fever up to 40 °C (104 °F), petechial or maculopapular rash of the trunk and occasionally the limbs, and arthralgia or arthritis affecting multiple joints.[12] Other nonspecific symptoms can include headache, nausea, vomiting, conjunctivitis, slight photophobia, and partial loss of taste.[13] Ocular inflammation from chikungunya may present as iridocyclitis, or uveitis. Retinal lesions may also occur.[14] Swelling of legs is observed in many people, the cause of which remains obscure as it is not related to any cardiovascular, renal, or hepatic abnormalities. Typically, the fever lasts for two days and then ends abruptly. However, other symptoms, namely joint pain, intense headache, insomnia and an extreme degree of prostration, last for a variable period, usually about five to seven days.[12] People have complained of joint pains for much longer time periods, some as long as two years, depending on their age.[15][16] Recovery from the disease varies by age. Younger people recover within five to 15 days; middle-aged people recover in 1.0 to 2.5 months. Recovery is longer for the elderly. The severity of the disease, as well as its duration, is less in younger people and pregnant women. In pregnant women, no untoward effects are noticed after the infection.
  • Observations during recent epidemics have suggested chikungunya may cause long-term symptoms following acute infection. During the La Reunion outbreak in 2006, more than 50% of subjects over the age of 45 reported long-term musculoskeletal pain[17] with up to 60% of people reporting prolonged arthralgia three years following initial infection.[18] A study of imported cases in France reported that 59% of people still suffered from arthralgia two years after acute infection.[19] Following a local epidemic of chikungunya in Italy, 66% of people reported muscles pains, joint pains, or asthenia at one year after acute infection.[20] Long-term symptoms are not an entirely new observation; long-term arthritis was observed following an outbreak in 1979.[21] Common predictors of prolonged symptoms are increased age and prior rheumatological disease.[17][18][20][22] The cause of these chronic symptoms is currently not fully known. Markers of autoimmune or rheumatoid disease have not been found in people reporting chronic symptoms.[18][23] However, some evidence from humans and animal models suggests chikungunya may be able to establish chronic infections within the host. Viral antigen was detected in a muscle biopsy of a people suffering a recurrent episode of disease three months after initial onset.[24] Additionally, viral antigen and RNA were found in synovial macrophages of a person during a relapse of musculoskeletal disease 18 months after initial infection.[25] Several animal models have also suggested chikungunya virus may establish persistent infections. In a mouse model, viral RNA was detected specifically in joint-associated tissue for at least 16 weeks after inoculation, and was associated with chronic synovitis.[26] Similarly, another study reported detection of a viral reporter gene in joint tissue of mice for weeks after inoculation.[27] In a nonhuman primate model, chikungunya virus was found to persist in the spleen for at least six weeks.[28]
  • The most effective means of prevention are protection against contact with the disease-carrying mosquitoes and mosquito control.[9] These include using insect repellents with substances such as DEET (N,N-diethyl-meta-toluamide; also known as N,N'-diethyl-3-methylbenzamide or NNDB), icaridin (also known as picaridin and KBR3023), PMD (p-menthane-3,8-diol, a substance derived from the lemon eucalyptus tree), or IR3535. Wearing bite-proof long sleeves and trousers also offers protection. In addition, garments can be treated with pyrethroids, a class of insecticides that often has repellent properties. Vaporized pyrethroids (for example in mosquito coils) are also insect repellents. Securing screens on windows and doors will help to keep mosquitoes out of the house. In the case of the day-active A. aegypti and A. albopictus, however, this will have only a limited effect, since many contacts between the mosquitoes and humans occur outside.

  • In those who have more than two weeks of arthritis, ribavirin may be useful.[9] The effect of chloroquine is not clear.[9] It does not appear to help acute disease, but tentative evidence indicates it might help those with chronic arthritis.[9] Steroids do not appear useful, either.[9]
  • Currently, no specific treatment is available.[9] Attempts to relieve the symptoms include the use of NSAIDs such as naproxen or paracetamol (acetaminophen) and fluids.[9] Aspirin is not recommended.[57]

El Salvador says nearly 30,000 infected with mosquito-borne chikungunya  - NY... - 0 views

  • El Salvador has detected nearly 30,000 cases of the painful mosquito-borne viral disease chikungunya, and has undertaken measures to prevent the disease-carrying mosquitoes breeding, the head of the country's emergency services said on Wednesday.
  • Since June, when the first case was reported, there have been 29,704 people infected by the virus, with 204 of them hospitalized, Jorge Melendez told Reuters. "Having never been in contact with this strain, the Salvadoran population has no defense," Melendez said, adding that nobody has died from the outbreak. Melendez said most of the cases have been reported in the capital city of San Salvador, where authorities have been cleaning rivers and fumigating. Infection with the virus, spread by two mosquito species, typically is not fatal but can cause debilitating symptoms including fever, headache and severe joint pain lasting weeks or months. There is no current treatment and no licensed vaccine to prevent it. The virus showed up for the first time in the Americas late last year. In the United States, locally transmitted infections — as opposed to infections in Americans traveling abroad — have been reported for the first time this year.

Chinese music - Wikipedia, the free encyclopedia - 0 views

  • The term guoyue, or national music, became popular in early 20th century and was used loosely to include all music written for Chinese instruments in response to a particular nationalistic consciousness.[11] The term however may have slightly different meaning when used by different Chinese communities. Originally it is used only referred to the music of the Han Chinese, later it may also include music of various ethnic minorities in China. In the new Republic of China in Taiwan, Guoyue emphasized music of the mainland China over the Taiwanese local traditions. In mainland China a new term minyue (民乐, short for minzu yinyue or "people's music") was coined post-1949 in place of guoyue to encompass all compositions and genres for traditional instruments. In other Chinese communities, it may also be referred to as huayue (for example in Singapore) or zhongyue (in Hong Kong)

  • The shakuhachi is a flute made of bamboo that's played by blowing on one end. There are four holes in the front and one in the back, and so it's sometimes called a "five-holed bamboo flute" in English. These five holes are enough to produce a complete range of sounds; in fact, it's the small number of holes that gives the shakuhachi its distinctively poignant tone.
