Respiratory syncytial virus infection:
Signs and symptoms
(Professional Guide to Diseases (Eighth Edition))
Clinical features of RSV infection vary in severity from mild, coldlike symptoms to bronchiolitis or bronchopneumonia and, in a few patients, severe, life-threatening lower respiratory tract infections. Symptoms usually include coughing, wheezing, malaise, pharyngitis, dyspnea, and inflamed mucous membranes in the nose and throat. Reinfection is common, producing milder symptoms than the primary infection.
Otitis media is a common complication of RSV in infants. RSV has also been identified in patients with a variety of central nervous system disorders, such as meningitis and myelitis.

Ebola virus infection:
Signs and symptoms
(Professional Guide to Diseases (Eighth Edition))
The patient's health history usually reveals contact with an infected person. However, no clear line of infection may be apparent at the beginning of an Ebola virus outbreak. The patient usually complains of flulike signs and symptoms (such as headache, malaise, myalgia, fever, cough, and sore throat), which first appear within 3 days of infection.
As the virus spreads through the body, inspection reveals bruising as capillaries rupture and dead blood cells infiltrate the skin. A maculopapular eruption appears after the fifth day of infection. The patient may also display melena, hematemesis, epistaxis, and bleeding gums. As the infection progresses, severe complications, including liver and kidney dysfunction, dehydration, and hemorrhage, may develop. In pregnant women, the Ebola virus leads to abortion and massive hemorrhage.
In the final stages of the disease, the skin blisters and sloughs off, blood seeps from all body orifices, and the patient begins vomiting his liquefied internal organs. Death usually results during the second week of illness from organ failure or hemorrhage.

Viral hepatitis:
Signs and symptoms
(Professional Guide to Diseases (Eighth Edition))
Assessment findings are similar for the different types of hepatitis. Typically, signs and symptoms progress in several stages.
In the prodromal (preicteric) stage, the patient typically complains of easy fatigue and anorexia (possibly with mild weight loss), generalized malaise, depression, headache, weakness, arthralgia, myalgia, photophobia, and nausea with vomiting. He also may describe changes in his senses of taste and smell.
Assessment of the patient’s vital signs may reveal a fever of 100° to 102° F (37.8° to 38.9° C). As the prodromal stage ends, usually 1 to 5 days before the onset of the clinical jaundice stage, inspection of urine and stool specimens may reveal dark-colored urine and clay-colored stools.
If the patient has progressed to the clinical jaundice stage, he may report pruritus, abdominal pain or tenderness, and indigestion. Early in this stage, he may complain of anorexia; later, his appetite may return. Inspection of the sclerae, mucous membranes, and skin may reveal jaundice, which can last for 1 to 2 weeks. Jaundice indicates that the damaged liver is unable to remove bilirubin from the blood; however, its presence doesn’t indicate the severity of the disease. Occasionally, hepatitis occurs without jaundice.
During the clinical jaundice stage, inspection of the skin may detect rashes, erythematous patches, or urticaria, especially if the patient has hepatitis B or C. Palpation may disclose abdominal tenderness in the right upper quadrant, an enlarged and tender liver and, in some cases, splenomegaly and cervical adenopathy.
During the recovery (posticteric) stage, most of the patient’s symptoms decrease or subside. On palpation, a decrease in liver enlargement may be noted. The recovery phase commonly lasts from 2 to 12 weeks, although sometimes this phase lasts longer in the patient with hepatitis B, C, or E.Little is known about hepatitis G.

A maculopapular eruption appears after the 5th day of infection, followed by desquamation. The patient may also display melena, hematemesis, epistaxis, and bleeding gums. At day 10 or 12, the fever may break and the patient eventually recovers. If the infection progresses, severe complications, including liver and kidney dysfunction, dehydration, and hemorrhage, may develop. In pregnant women, Ebola virus disease leads to abortion and massive hemorrhage.

Human immunodeficiency virus infection:
Signs and symptoms
(Handbook of Diseases)
HIV infection manifests itself in many ways.
Clinical tip After a high-risk exposure and inoculation, the infected person usually experiences a mononucleosis-like syndrome, which may be attributed to the flu or another virus, and then may remain asymptomatic for years. In this latent stage, the only sign of HIV infection is laboratory evidence of seroconversion.
When symptoms appear, they may take many forms:
❑ persistent generalized adenopathy
❑ nonspecific symptoms (weight loss, fatigue, night sweats, fevers)
❑ neurologic symptoms resulting from HIV encephalopathy
❑ opportunistic infection or cancer.
The clinical course varies slightly in children with AIDS. Apparently, their incubation time is shorter, with a mean of 17 months. Signs and symptoms resemble those in adults, except for findings related to STDs. Children show virtually all of the opportunistic infections observed in adults, with a higher incidence of bacterial infections, such as otitis media, sepsis, chronic salivary gland enlargement, Mycobacterium avium complex function, and pneumonias, including Pneumocystis carinii and lymphoid interstitial pneumonias.

Hepatitis, viral:
Signs and symptoms
(Handbook of Diseases)
Assessment findings are similar for the different types of hepatitis. Typically, signs and symptoms progress in three stages — prodromal (preicteric), clinical (icteric), and recovery (posticteric).
Prodromal stage
In the prodromal stage, the patient typically complains of easy fatigue, anorexia (possibly with mild weight loss), generalized malaise, depression, headache, weakness, arthralgia, myalgia, photophobia, and nausea with vomiting. He also may describe changes in his senses of taste and smell.
Assessment of vital signs may reveal a temperature of 100° to 102° F (37.8° to 38.9° C). As the prodromal stage draws to a close, usually 1 to 5 days before the onset of the clinical jaundice stage, inspection of urine and stool specimens may reveal dark-colored urine and clay-colored stools.
Clinical jaundice stage
If the patient has progressed to the clinical jaundice stage, he may report pruritus, abdominal pain or tenderness, and indigestion. Early in this stage, he may complain of anorexia; later, his appetite may return. Inspection of the sclerae, mucous membranes, and skin may reveal jaundice, which can last for 1 to 2 weeks.
Jaundice indicates that the damaged liver can’t remove bilirubin from the blood, but it doesn’t indicate the severity of the disease. Occasionally, hepatitis occurs without jaundice.
During the clinical jaundice stage, inspection of the skin may detect rashes, erythematous patches, and urticaria, especially if the patient has hepatitis B or C. Palpation may disclose abdominal tenderness in the right upper quadrant, an enlarged and tender liver and, in some cases, splenomegaly and cervical adenopathy.
Recovery stage
During the recovery stage, most of the patient’s symptoms decrease or subside. On palpation, a decrease in liver enlargement may be noted. The recovery stage commonly lasts from 2 to 12 weeks, although sometimes this stage lasts longer in patients with hepatitis B, C, or E.
