Boston public health officials have confirmed four cases of the mosquito-borne virus chikungunya in the Boston-area.
The viral disease is transmitted to people by mosquitoes, according to the Boston Public Health Commission, although those who have been diagnosed are believed to have contracted the virus while traveling in the Caribbean.
Health officials said they have not discovered any mosquitos carrying the virus in the United States, but that it is possible that chikungunya will spread to mosquitoes in new areas, including the US.
A Boston health spokeswoman told WCVB that no public threat or advisory has been issued locally.
Common symptoms of chikungunya include fever, joint pain, headache, muscle pain, joint swelling, or rash, and usually last up to a week.
