A Boston Public Health Commission official confirmed Saturday that there have been four cases of the chikungunya virus diagnosed in the last week.
Four people in the Boston area all tested positive for the virus, which is transmitted by mosquitoes.
The most common symptoms of the disease include fever and joint pain. Other symptoms include headache, muscle pain, joint swelling or a rash. The Center for Disease Control website states that the virus is not often fatal, but symptoms can be disabling.
People who develop the symptoms above should visit a doctor. There is no medicine to treat the disease, but the infected can decrease the severity of symptoms by getting rest, drinking lots of fluids and taking medicine to relieve pain.
