Several days after the appearance of early symptoms, a distinctive bright red rash may appear on your child's face — usually on both cheeks. Eventually it may spread to the arms, trunk, thighs and buttocks, where the rash has a pink, lacy, slightly raised appearance.
The rash may be itchy, especially on the soles of the feet. Generally, the rash occurs near the end of the illness. It's possible to mistake the rash for other viral rashes or a medicine-related rash. The rash may come and go for up to three weeks, becoming more visible when your child is exposed to extreme temperatures or spends time in the sun. Adults don't usually develop the slapped-cheek rash. Instead, the most noticeable symptom of parvovirus infection in adults is joint soreness, lasting days to weeks.
Joints most commonly affected are the hands, wrists, knees and ankles. Generally, you don't need to see a doctor for parvovirus infection. But if you or your child has an underlying condition that may increase the risk of complications, make an appointment with your doctor. These conditions include:. The human parvovirus B19 causes parvovirus infection. This is different from the parvovirus seen in dogs and cats, so you can't get the infection from a pet or vice versa.
Human parvovirus infection is most common among elementary school-age children during outbreaks in the winter and spring months, but anyone can become ill with it anytime of the year. It spreads from person to person, just like a cold, often through breathing, coughing and saliva, so it can spread through close contact between people and hand-to-hand contact.
Parvovirus infection can also spread through blood. An infected pregnant woman can pass the virus to her baby. The illness is contagious in the week before the rash appears.
Once the rash appears, you or your child are no longer considered contagious and don't need to be isolated. Parvovirus infection can cause serious complications for people with anemia.
Anemia is a condition in which cells that carry oxygen to all the parts of your body red blood cells are used up faster than your bone marrow can replace them. Parvovirus infection in people with anemia may stop the production of red blood cells and cause an anemia crisis. People with sickle cell anemia are at particular risk. Parvovirus infection during pregnancy sometimes affects red blood cells in the fetus.
Not necessarily. Some dogs will show all of the symptoms of canine parvo and some dogs may just have one or two symptoms. No, parvo viral particles are microscopic. How microscopic? Unlike worms that you can actually see moving around in dog feces, you will not see the potentially billions of viral particles in feces contaminated with parvo virus. Incubation is the amount of time from first contact, to first symptoms.
