By 2. Headache
Headache is a common early symptom of fifth disease and often appears during the first few days of infection. It typically develops alongside a low-grade fever or mild cold-like signs as the body’s immune system responds to the virus. Many people describe the discomfort as a dull, steady ache rather than sharp or throbbing pain.
The headache may also be accompanied by general fatigue or a feeling of pressure in the forehead or temples. These sensations occur as the body releases inflammatory chemicals that help fight the viral infection. Because these early immune responses affect the whole body, headaches may appear even before more recognizable symptoms develop.
This headache often occurs before the well-known cheek rash becomes visible. Because it appears early and resembles symptoms of a routine viral illness, fifth disease is frequently mistaken for a simple cold at this stage. The headache may last for several days and usually begins to ease as other symptoms, such as rash or joint discomfort, start to appear.
3. Fever
Fever is often one of the first signs of fifth disease and usually appears before the well-known cheek rash. It develops early in the infection as the body’s immune system responds to the virus.
In most cases, children experience a low-grade fever that may resemble a common cold and can go unnoticed at first. This early phase often occurs alongside other mild symptoms such as headache, runny or stuffy nose, sore throat, or general tiredness. During this period, the person is more likely to spread the infection to others through respiratory droplets.
As the illness progresses and the rash appears, the risk of transmission usually decreases. The fever commonly stays below 102°F (38.9°C) and improves within a few days without special treatment. Some people, especially adults, may have only a very mild fever or no fever at all. Fever often fades as other symptoms become more noticeable.
4. Sore Throat
A sore throat can appear early in fifth disease and often develops during the initial stage of infection. At this point, the illness is commonly mistaken for a simple cold. The throat may feel dry, scratchy, or painful when swallowing. Mild redness or swelling at the back of the throat can cause discomfort while eating and drinking, although the pain is usually mild.
This irritation occurs when the virus infects the upper respiratory tract and triggers inflammation in the tissues lining the throat. As the immune system responds, the throat lining may become more sensitive, which can make swallowing feel uncomfortable. The soreness may come and go during the first few days of illness.
This symptom often occurs alongside other cold-like signs such as low-grade fever, headache, runny or stuffy nose, or cough. These symptoms are most common when the virus spreads easily to others, often before the rash appears. In most cases, the sore throat improves on its own within a few days as the infection progresses.
5. Pruritus
Pruritus refers to itching of the skin. In fifth disease, it usually appears after the bright red cheek rash and develops as the rash spreads to other parts of the body. It most commonly affects the arms, legs, chest, back, or buttocks.
As the rash develops, the skin may appear pink or red, form a lacy or blotchy pattern, and feel slightly raised to the touch. The skin does not usually blister or ooze. The itching is often mild to moderate. Some children barely notice it, while others may scratch more often.
The itching occurs as the body’s immune response causes mild inflammation in the skin. This reaction can stimulate nerve endings near the surface of the skin, creating the urge to scratch. In some individuals, the itching may appear at the same time as the rash, while in others it becomes more noticeable after the rash has already spread.
Heat, sunlight, or physical activity can make both the rash and itching more noticeable. Warm baths or tight clothing may also increase skin irritation. Repeated scratching can irritate the skin surface and lead to dryness or small scratch marks.
6. Coryza
Coryza refers to a runny or stuffy nose and is a common early symptom of fifth disease. It often appears during the initial stage of infection, before the cheek and body rash develops. As the virus affects the lining of the nasal passages, irritation occurs. This leads to clear nasal discharge and a feeling of nasal congestion.
The nasal lining may also become mildly swollen as the immune system reacts to the virus. This swelling can narrow the nasal passages and make breathing through the nose more difficult. Because of this, some children may breathe through the mouth or sound slightly congested when speaking. Coryza commonly occurs alongside other mild, cold-like signs such as low-grade fever, headache, mild sore throat, or general tiredness.
Sneezing may also occur as the irritated nasal passages react to the infection. In many cases, these symptoms remain mild and improve on their own within a few days, often before the characteristic rash of fifth disease appears.
7. Abdominal Pain
Abdominal pain is not among the most common signs of fifth disease, but it can occur in some children and adults. When present, it usually appears during the early stage of illness and may develop alongside fever, headache, or other mild viral symptoms. In some cases, it occurs before the characteristic rash becomes visible.
The virus can cause general body discomfort that may include mild stomach pain. This pain is typically dull and spread out rather than sharp or focused in one specific area. Children may say their stomach hurts and may also show a reduced appetite, mild nausea, or increased tiredness. These digestive complaints may develop as the immune system reacts to the viral infection and temporarily affects the digestive tract.
Some individuals may also feel a sense of abdominal fullness or mild cramping during this stage. Because the discomfort is usually mild and short-lasting, it often improves as the body begins to control the infection and other symptoms progress. Severe or persistent abdominal pain is not typical of fifth disease.
8. Arthralgia
Arthralgia refers to joint pain. It is more common in teens and adults with fifth disease than in young children. The pain most often affects the hands, wrists, knees, and ankles. It usually occurs on both sides of the body at the same time. Some people also notice mild joint swelling, stiffness, or reduced range of motion.
These symptoms are more noticeable in the morning or after periods of rest. Joint pain may develop after the rash appears or may occur without a noticeable rash at all. In some adults, it becomes the main or only symptom of the illness. The joints may feel sore during movement, gripping objects, or walking.
The discomfort occurs when the immune system reacts to the virus and temporarily affects the tissues surrounding the joints. Mild inflammation can make the joint lining more sensitive, leading to stiffness and soreness. In most cases, the symptoms are temporary and improve as the immune response settles.
Joint discomfort may last from a few days to several weeks. In adults, it may last longer but usually improves over time and does not cause permanent joint damage.
9. Chills
Chills can appear early in fifth disease, often before the cheek rash develops. They usually occur with a low-grade fever and can cause sudden feelings of cold, even in a warm room. Chills happen as the body raises its temperature to fight the virus.
As the immune system responds, the brain signals the body to conserve and generate heat, which can trigger shivering. The skin may feel cool or goose-bumped while the internal body temperature is rising. Some individuals may also feel tired, achy, or generally unwell during this stage of infection.
In most cases, the fever linked with chills remains mild and does not rise very high. Chills may come and go for several hours or during the first day or two of illness. As the illness progresses and the rash appears, chills usually fade. At this stage, the person becomes less likely to spread the virus.
10. Red Cheeks
Red cheeks are often the first clear visible sign of fifth disease. The rash gives the face a bright red appearance, sometimes described as a “slapped cheek” look, and usually affects both cheeks at the same time. This facial rash typically appears a few days after mild cold-like symptoms such as low-grade fever, runny or stuffy nose, sore throat, or headache.
By the time the cheeks turn red, the child often feels well and may seem back to normal. The skin on the cheeks may feel warm and can be mildly itchy, but it is usually not painful. The redness is smooth and evenly colored and does not usually form blisters or open sores.
The area around the mouth often remains pale, which can make the cheek redness appear more noticeable. The rash on the cheeks usually lasts several days before fading or spreading to other parts of the body, such as the arms, legs, or trunk. At this stage, the person is usually no longer contagious.
11. Anemia
Anemia can develop as a complication of fifth disease when the virus affects the bone marrow, where red blood cells are produced. Because red blood cells carry oxygen to body tissues, a reduced number can lead to noticeable symptoms. However, people with underlying blood disorders such as sickle cell disease or thalassemia are at higher risk.
In these individuals, the virus can temporarily slow or stop red blood cell formation, causing a sudden drop in blood levels. This may lead to symptoms such as unusual tiredness, weakness, pale skin, shortness of breath, or a fast heartbeat. Some people may also feel dizzy or have difficulty with normal physical activity because the body receives less oxygen.
This condition is sometimes called a temporary aplastic crisis because the bone marrow briefly stops producing enough red blood cells. Although this reaction can be serious in people with existing blood disorders, it is uncommon in otherwise healthy individuals.
12. Miscarriage
Fifth disease is usually mild, but infection during pregnancy can raise concern. If a pregnant woman becomes infected, the virus can pass to the unborn baby. This does not happen often, but in some cases it can affect the pregnancy.
A miscarriage refers to the loss of a pregnancy before 20 weeks. The overall risk related to fifth disease is low, though it is higher when infection occurs during the first half of pregnancy. In rare cases, the virus can interfere with the baby’s red blood cell production, leading to severe anemia and related complications. Severe anemia in the fetus may cause a condition called hydrops fetalis, in which fluid builds up in body tissues and organs.
Some pregnant women may experience only mild symptoms or no symptoms at all, which can delay recognition of infection. Because of this, healthcare providers may monitor the pregnancy more closely with blood tests or ultrasound if exposure to the virus is suspected.
13. Treatment
Fifth disease usually resolves on its own, and most healthy children and adults recover without the need for special medical treatment. Care focuses on easing symptoms while the body clears the virus. For fever, joint pain, headache, or body aches, doctors may recommend over-the-counter pain relievers like acetaminophen or NSAIDs.
Rest is important, especially during the early stages of illness when symptoms are most noticeable. Drinking enough fluids and avoiding heavy physical activity, particularly during the fever stage, can help support recovery. If the rash becomes itchy, soothing lotions, cool compresses, or an oral antihistamine may be recommended to calm skin irritation.
Joint pain may last longer in adults. Gentle movement, stretching, and warm compresses can help reduce stiffness and swelling as the joints recover. Some people may need closer medical care. Individuals with blood disorders, weakened immune systems, or pregnancy-related concerns may require monitoring or supportive treatment.
14. Prevention
Fifth disease spreads mainly through droplets from the nose and mouth. The virus spreads most easily before the rash appears, when symptoms may be mild or not noticed at all. Regular handwashing helps lower the risk of infection.
Hands should be washed with soap and water for at least 20 seconds, especially after coughing, sneezing, wiping the nose, or being in public places. Alcohol-based hand sanitizers can be used when soap and water are not available. Covering the mouth and nose when coughing or sneezing also helps reduce spread.
Avoiding the sharing of drinking glasses, utensils, towels, or other personal items can also reduce the chance of spreading the virus. Cleaning frequently touched surfaces such as door handles, toys, and tables may help limit transmission in shared environments.
Children and adults should avoid close contact with people who are sick and stay home when symptoms appear. Schools and daycare centers can help by cleaning shared surfaces and toys and keeping rooms well ventilated. There is no vaccine for the fifth disease, so good hygiene is the main way to reduce the risk of infection.
