Chikungunya, diagnosed commonly in India, Caribbean, Central and South America and Africa, is caused by a mosquito bite. Common symptoms of this disease include fever and rash which continue for days. It is also accompanied by severe joint pain which lasts for some months and sometimes for more than a year. However, the researchers from the Washington University School of Medicine in St. Louis have analyzed that patients affected with rheumatoid arthritis also have same symptoms. Similar symptoms and test results often results in wrong diagnosis and mistreatment.
According to the recommendations of the researchers the travel and medical history of each patient must be considered for avoiding wrong diagnosis. Sometimes, patients affected with Chikungunya are treated with drugs used for the treatment of rheumatoid arthritis, which makes the condition worse.
