käsivarsiä

Käsivarsiä, also known as hand-foot-and-mouth disease, is a common viral infection that primarily affects children under the age of five. It is caused by one of several enteroviruses, particularly coxsackieviruses A16 and coxsackieviruses B1-B5. The disease is characterized by a fever, rash, and sore throat, with the distinctive feature being the appearance of small, red spots or blisters on the palms of the hands and soles of the feet. These lesions can be painful and may leave a white or yellowish crust when they heal. The infection is highly contagious and is typically spread through respiratory droplets or direct contact with infected bodily fluids.

The incubation period for käsivarsiä is usually between one to five days. Symptoms usually begin with a fever, sore throat, and mild rash, which may be followed by the characteristic hand and foot lesions. The disease is usually self-limiting and resolves within 7-10 days without specific treatment. However, in some cases, complications such as dehydration, secondary bacterial infections, or even encephalitis (inflammation of the brain) can occur, particularly in young children or those with weakened immune systems.

Prevention of käsivarsiä involves good hygiene practices, such as frequent hand washing, avoiding close contact with infected individuals, and practicing good respiratory hygiene. There is no specific antiviral treatment for käsivarsiä, but supportive care, including hydration and pain relief, can help manage symptoms. In severe cases, hospitalization may be necessary to manage complications. Vaccination is not currently available for käsivarsiä, but efforts are ongoing to develop an effective vaccine.
