Is the coxsackievirus contagious?
Yes, coxsackieviruses are contagious person to person. These viruses are transmitted mainly by the fecal-oral route and by respiratory aerosols. Droplets containing viruses that land on objects like toys or utensils may occasionally transmit the viruses indirectly to uninfected individuals.
How long are coxsackieviruses contagious?
Coxsackieviruses are most contagious during the first week of symptoms. However, viable virus microbes have been found in respiratory tracts for up to three weeks and then in feces up to eight weeks after initial infection, but during this time, the viruses are less contagious.
What is the incubation period for coxsackievirus infections?
The incubation period for coxsackievirus infections is relatively short; it lasts about one to two days with a range of about one to five days.
What are coxsackievirus infection symptoms and signs?
The most frequent signs and symptoms of coxsackievirus infections are initially fever, a poor appetite, and respiratory illness, including sore throat, cough, and malaise (feeling tired). This incubation period lasts about one to two days. Sore areas in the mouth develop in about a day or two after the initial fever and develop into small blisters that often ulcerate. Many infected people (usually children 10 years of age and younger) go on to develop a rash that itches on the palms of the hands and the soles of the feet. Other areas such as the buttocks and genitals may be involved. Some patients develop conjunctivitis. These symptoms usually last about seven to 10 days, and the person usually recovers completely. The individuals are most contagious for about a week after symptoms begin, but because the virus can be shed by the infected individual sometimes for weeks after the symptoms have gone away, the person may be mildly contagious for several weeks.
Infrequently, the infection may result in temporary fingernail or toenail loss (termed onychomadesis) and chest or abdominal muscle pain. Rarely, the disease may progress to cause viral meningitis (headache, stiff neck), myocarditis (heart muscle infection), pericarditis (inflammation/fluid collection of the tissue surrounding the heart), or encephalitis (brain inflammation).
Infection with EV-71 results in a higher incidence of neurologic involvement with symptoms such as a polio-like syndrome, meningitis, encephalitis, Guillain-Barré syndrome, and/or ataxia.
