Rocky Mountain spotted fever:
Signs and symptoms
(Professional Guide to Diseases (Eighth Edition))
The incubation period is usually about 7 days, but it can range from 2 to 14 days. Generally, the shorter the incubation time, the more severe the infection. Signs and symptoms, which usually begin abruptly, include a persistent temperature of 102° to 104° F (38.9° to 40° C); a generalized, excruciating headache; nausea and vomiting; and aching in the bones, muscles, joints, and back. In addition, the tongue is covered with a thick white coating that gradually turns brown as the fever persists and rises.
Initially, the skin may simply appear flushed. Between days 2 and 5, eruptions begin around the wrists, ankles, or forehead; within 2 days, they cover the entire body, including the scalp, palms, and soles. The rash consists of erythematous macules 1 to 5 mm in diameter that blanch on pressure; if untreated, the rash may become petechial and maculopapular. By the third week, the skin peels off and may become gangrenous over the elbows, fingers, and toes.
The pulse is strong initially, but it gradually becomes rapid (possibly reaching 150 beats/minute) and thready.
Alert A rapid pulse rate and hypotension (systolic pressure less than 90 mm Hg) herald imminent death from complete vascular collapse.
Other signs and symptoms include a bronchial cough, a rapid respiratory rate (as high as 60 breaths/minute), anorexia, constipation, abdominal pain, hepatomegaly, splenomegaly, insomnia, restlessness and, in extreme cases, delirium. Urine output falls to half of the normal level or less, is dark in color, and contains albumin. Complications, although uncommon, include lobar pneumonia, otitis media, pa-rotitis, disseminated intravascular coagulation (DIC) and, possibly, renal failure. In rare cases, RMSF leads to death.

Colorado tick fever:
Signs and symptoms
(Professional Guide to Diseases (Eighth Edition))
After a 3- to 6-day incubation period, Colorado tick fever begins abruptly with chills; temperature of 104° F (40° C); severe aching of back, arms, and legs; lethargy; and headache with eye movement such as extraocular movement. Photophobia, abdominal pain, nausea, and vomiting may occur. Rare effects include petechial or maculopapular rashes and central nervous system involvement. Symptoms subside after several days but return within 2 to 3 days and continue for 3 more days before slowly disappearing. Complete recovery usually follows.

Lassa fever:
Signs and symptoms
(Professional Guide to Diseases (Eighth Edition))
After a 7- to 18-day incubation period, this disease produces a fever that persists for 2 to 3 weeks, exudative pharyngitis, oral ulcers, lymphadenopathy with swelling of the face and neck, purpura, conjunctivitis, and bradycardia. Severe infection may also cause hepatitis, myocarditis, pleural infection, encephalitis, and permanent unilateral or bilateral deafness.
Virus multiplication in reticuloendothelial cells causes capillary lesions that lead to erythrocyte and platelet loss; mild to moderate thrombocytopenia (with a tendency toward bleeding); and secondary bacterial infection. These capillary lesions may also cause focal hemorrhage in the stomach, small intestine, kidneys, lungs, and brain and, possibly, hemorrhagic shock and peripheral vascular collapse.

Relapsing fever:
Signs and symptoms
(Professional Guide to Diseases (Eighth Edition))
The incubation period for relapsing fever is 5 to 15 days (the average is 7 days). Clinically, tick- and louse-borne diseases are similar. Both begin suddenly, with a temperature approaching 105° F (40.6° C), prostration, headache, severe myalgia, arthralgia, diarrhea, vomiting, coughing, and eye or chest pains. Splenomegaly is common; hepatomegaly and lymphade-nopathy may occur. During febrile periods, the victim's pulse and respiratory rates rise, and a transient macular rash may develop over his torso.
The first attack usually lasts from 3 to 6 days; then the patient's temperature drops quickly and is accompanied by profuse sweating. A skin rash on the trunk lasting 1 to 2 days is common after the primary febrile episode. The rash may be petechiae, macular, or papular. About 5 to 10 days later, a second febrile, symptomatic period begins. In louse-borne infection, additional relapses are unusual; but, in tick-borne cases, a second or third relapse is common. As the afebrile intervals become longer, relapses become shorter and milder because of antibody accumulation. Relapses are possibly due to antigenic changes in the Borrelia organism.
Complications from relapsing fever include nephritis, bronchitis, pneumonia, endocarditis, seizures, cranial nerve lesions, paralysis, and coma. Death may occur from hyperpyrexia, massive bleeding, circulatory failure, splenic rupture, or a secondary infection.

Rheumatic fever and rheumatic heart disease:
Signs and symptoms
(Professional Guide to Diseases (Eighth Edition))
In 95% of patients, rheumatic fever characteristically follows a streptococcal infection that appeared a few days to 6 weeks earlier. A temperature of at least 100.4° F (38° C) occurs, and most patients complain of migratory joint pain or polyarthritis. Swelling, redness, and signs of effusion usually accompany such pain, which most commonly affects the knees, ankles, elbows, or hips. In 5% of patients (generally those with carditis), rheumatic fever causes skin lesions such as erythema marginatum, a nonpruritic, macular, transient rash that gives rise to red lesions with blanched centers. Rheumatic fever may also produce firm, movable, nontender, subcutaneous nodules about 3 mm to 2 cm in diameter, usually near tendons or bony prominences of joints (especially the elbows, knuckles, wrists, and knees) and less often on the scalp and backs of the hands. These nodules persist for a few days to several weeks and, like erythema marginatum, often accompany carditis.
Later, rheumatic fever may cause transient chorea, which develops up to 6 months after the original streptococcal infection. Mild chorea may produce hyperirritability, a deterioration in handwriting, or an inability to concentrate. Severe chorea (Sydenham’s chorea) causes purposeless, nonrepetitive, involuntary muscle spasms; poor muscle coordination; and weakness. Chorea always resolves without residual neurologic damage.
The most destructive effect of rheumatic fever is carditis, which develops in up to 50% of patients and may affect the endocardium, myocardium, pericardium, or the heart valves. Pericarditis causes a pericardial friction rub and, occasionally, pain and effusion. Myocarditis produces characteristic lesions called Aschoff bodies (in the acute stages) and cellular swelling and fragmentation of interstitial collagen, leading to formation of a progressively fibrotic nodule and interstitial scars. Endocarditis causes valve leaflet swelling, erosion along the lines of leaflet closure, and blood, platelet, and fibrin deposits, which form beadlike vegetations. Endocarditis affects the mitral valve most often in females; the aortic, most often in males. In both females and males, endocarditis affects the tricuspid valves occasionally and the pulmonic only rarely.
Severe rheumatic carditis may cause heart failure with dyspnea; right upper quadrant pain; tachycardia; tachypnea; a hacking, nonproductive cough; edema; and significant mitral and aortic murmurs. The most common of such murmurs include:
❑ a systolic murmur of mitral insufficiency (high-pitched, blowing, holosystolic, loudest at apex, possibly radiating to the anterior axillary line)
❑ a midsystolic murmur due to stiffening and swelling of the mitral leaflet
❑ occasionally, a diastolic murmur of aortic insufficiency (low-pitched, rumbling, almost inaudible). Valvular disease may eventually result in chronic valvular stenosis and insufficiency, including mitral stenosis and insufficiency, and aortic insufficiency. In children, mitral insufficiency remains the major sequela of rheumatic heart disease.

Rheumatic fever and rheumatic heart disease:
Signs and symptoms
(Handbook of Diseases)
In 95% of patients, rheumatic fever characteristically follows a streptococcal infection that appeared a few days to 6 weeks earlier. A temperature of at least 100.4° F (38° C) occurs.
Joint pain
Most patients complain of migratory joint pain or polyarthritis. Swelling, redness, and signs of effusion usually accompany such pain, which most commonly affects the knees, ankles, elbows, or hips.
Skin lesions and nodules
In 5% of patients (generally those with carditis), rheumatic fever causes skin lesions, such as erythema marginatum. This nonpruritic, macular, transient rash gives rise to red lesions with blanched centers.
Rheumatic fever may also produce firm, movable, nontender, subcutaneous nodules ⅛" to ¾" (0.5 to 2 cm) in diameter, usually near tendons or bony prominences of joints (especially the elbows, knuckles, wrists, and knees) and less commonly on the scalp and backs of the hands. These nodules persist for a few days to several weeks and, like erythema marginatum, often accompany carditis.
Chorea
Later, rheumatic fever may cause transient chorea, which develops up to 6 months after the original streptococcal infection.
Mild chorea may produce hyperirritability, a deterioration in handwriting, or an inability to concentrate. Severe chorea causes purposeless, nonrepetitive, involuntary muscle spasms; poor muscle coordination; and weakness. Chorea always resolves without residual neurologic damage.
Carditis
The most destructive effect of rheumatic fever is carditis, which develops in up to 50% of patients. It may affect the endocardium, myocardium, pericardium, or the heart valves.
Pericarditis causes a pericardial friction rub and, occasionally, pain and effusion. Myocarditis produces characteristic lesions called Aschoff bodies (in the acute stages) and cellular swelling and fragmentation of interstitial collagen, leading to formation of a progressively fibrotic nodule and interstitial scars.
Endocarditis causes valve leaflet swelling, erosion along the lines of leaflet closure, and blood, platelet, and fibrin deposits, which form beadlike vegetations. Endocarditis usually affects the mitral valve in females and the aortic valve in males. In both sexes, endocarditis affects the tricuspid valves occasionally and the pulmonic valve only rarely.
Severe rheumatic carditis may cause heart failure with dyspnea, right-upper-quadrant pain, tachycardia, tachypnea, significant mitral and aortic murmurs, and a hacking, nonproductive cough.
The most common murmurs include:
❑ a systolic murmur of mitral insufficiency (high-pitched, blowing, holo-systolic, loudest at apex, possibly radiating to the anterior axillary line)
❑ a midsystolic murmur caused by stiffening and swelling of the mitral leaflet
❑ occasionally, a diastolic murmur of aortic insufficiency. Valvular disease may eventually result in chronic valvular stenosis and insufficiency, including mitral stenosis and insufficiency and aortic insufficiency. In children, mitral insufficiency remains the major after-effect of rheumatic heart disease.

Measles (Rubeola, First Disease):
Measles - signs & symptoms
(The 5-Minute Pediatric Consult)
- The disease involves fever, cough, conjunctivitis, or coryza with an erythematous rash, which has a characteristic progression.
- The rash appears on the face (often the nape of the neck, initially) and abdomen 14 days after exposure. The rash is erythematous and maculopapular and spreads from the head to the feet often becoming confluent at the more proximal sites.
- Pharyngitis, cervical lymphadenopathy, and splenomegaly may accompany the rash.
- Atypical measles:
- This group of young adults (2nd and 3rd decades of life) may become quite ill, with sudden onset of fever from 103–105°F associated with headache. The rash, unlike typical measles, appears 1st on the distal extremities and progresses in a cephalad direction.
- Virtually all patients with atypical measles have respiratory distress with clinical and radiographic signs of pneumonia, often with pleural effusions.
- Diagnosis depends on recognition and on acute and convalescent measles antibody titers.

Article Excerpts About Symptoms of Rocky Mountain spotted fever:
Rocky Mountain spotted fever: DVRD (Excerpt)
Initial signs and
symptoms of the disease include sudden onset of fever, headache, and
muscle pain, followed by development of rash. (Source: excerpt from Rocky Mountain spotted fever: DVRD)
Rocky Mountain spotted fever: Signs and Symptoms: DVRD (Excerpt)
The early clinical
presentation of Rocky Mountain spotted fever is nonspecific and
may resemble a variety of other infectious and
non-infectious diseases.
Initial symptoms may include:
- fever
- nausea
- vomiting
- severe headache
- muscle pain
- lack of appetite
Later signs and symptoms include:
- rash
- abdominal pain
- joint pain
- diarrhea
The classic triad of findings for this disease are
fever, rash, and history of tick bite. However, this combination is often
not identified when the patient initially presents for
care.
The rash first appears 2-5 days after the
onset of fever and is often not present or may be very subtle when the
patient is initially seen by a physician. Younger patients usually develop
the rash earlier than older patients. Most often it begins as small,
flat, pink, non-itchy spots (macules) on the wrists, forearms, and ankles
(Figure 13). These spots turn pale
when pressure is applied and eventually become
raised on the skin. The characteristic red, spotted (petechial) rash of Rocky
Mountain spotted fever is
usually not seen until the sixth day or later after onset of symptoms, and
this type of rash occurs in only 35% to 60% of patients with Rocky
Mountain spotted fever (Figure 14). The rash involves the palms or soles in as
many as 50% to 80% of patients; however, this distribution may not occur
until later in the course of the disease. As many as 10% to 15% of patients may never develop a rash. (Source: excerpt from Rocky Mountain spotted fever: Signs and Symptoms: DVRD)
