Pneumonia:
Signs and symptoms
(Professional Guide to Diseases (Eighth Edition))
The main symptoms of pneumonia are coughing, sputum production, pleuritic chest pain, shaking chills, shortness of breath, rapid shallow breathing, and fever. Physical signs vary widely, ranging from diffuse, fine crackles to signs of localized or extensive consolidation and pleural effusion. There may also be associated symptoms of headache, sweating, loss of appetite, excess fatigue, and confusion (in older people).
Complications include hypoxemia, respiratory failure, pleural effusion, empyema, lung abscess, and bacteremia, with spread of infection to other parts of the body, resulting in meningitis, endocarditis, and pericarditis.

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.

Pneumocystis carinii pneumonia:
Signs and symptoms
(Professional Guide to Diseases (Eighth Edition))
The patient typically has a history of an immunocompromising condition (such as HIV infection, leukemia, or lymphoma) or procedure (such as organ transplantation).
PCP begins insidiously with increasing shortness of breath and a nonproductive cough. Anorexia, generalized fatigue, and weight loss may follow. Although the patient may have hypoxemia and hypercapnia, he may not exhibit significant symptoms. He may, however, have a low-grade, intermittent fever.
Other signs and symptoms include tachypnea, dyspnea, accessory muscle use for breathing, crackles (in about one-third of patients), marked pallor, and decreased breath sounds (in advanced pneumonia). Cyanosis may appear with acute illness; pulmonary consolidation develops later.

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.

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.

Community-acquired Pneumonia:
Presentation
(Pediatric Infectious Disease)
Recent reviews have suggested that the presence of an increased respiratory rate
may be the best method to distinguish lower respiratory tract infection from
the more common upper respiratory tract infections. The World Health
Organization has issued guidelines for the clinical diagnosis of pneumonia in
developing countries; the guidelines state that tachypnea and intercostal
retractions are the best indications of lower respiratory tract disease.

Article Excerpts About Symptoms of Q fever:
Only about one-half of all people infected
with C. burnetii show signs of clinical illness. Most acute
cases of Q fever begin with sudden onset of one or more of the following: high fevers
(up to 104-105° F), severe headache, general malaise ,
myalgia , confusion, sore
throat, chills, sweats, non-productive cough, nausea, vomiting, diarrhea,
abdominal pain, and chest pain. Fever usually lasts for 1 to 2 weeks.
Weight loss can occur and persist for some time. Thirty to fifty percent
of patients with a symptomatic infection will develop pneumonia.
Additionally, a majority of patients have abnormal results on liver function tests
and some will develop hepatitis .
In general, most patients will recover to good health within several
months without any treatment. Only 1%-2% of people with acute Q fever
die of the disease. (Source: excerpt from Q Fever: DVRD)
Q fever as a Cause of Symptoms or Medical Conditions
When considering symptoms of Q fever, it is also important to consider Q fever as a possible cause of other medical conditions.
The Disease Database lists the following medical conditions that Q fever may cause:

Q fever: Onset and Incubation
Incubation period for Q fever: 2 to 4 weeks
Incubation period for Q fever: The incubation
period for Q fever varies depending on the number of organisms that
initially infect the patient. Infection with greater numbers of organisms
will result in shorter
incubation periods. Most patients become ill within 2-3 weeks after
exposure. Those who recover fully from infection may possess lifelong
immunity
against re-infection. (Source: excerpt from Q Fever: DVRD)
