Lung Infection Symptoms Biography

Include rhinitis, pharyngitis/tonsillitis and laryngitis often referred to as a common cold, and their complications: sinusitis, ear infection and ometimes bronchitis (though bronchi are generally classified as part of the lower respiratory tract.) Symptoms of URI's commonly include cough, sore throat, runny nose, nasal congestion, headache, low grade fever, facial pressure and sneezing. Onset of symptoms usually begins 1–3 days after exposure. The illness usually lasts 7–10 days. Group A beta hemolytic treptococcal pharyngitis/tonsillitis(strep throat) typically presents with a sudden onset of sore throat, pain with swallowing and fever. Strep throat does not usually cause runny nose, voice changes or cough.
Pain and pressure of the ear caused by a middle ear infection (Otitis media) and the reddening of the eye caused by viral Conjunctivitisare often associated with upper respiratory infections. Over 200 different viruses have been isolated in patients with URIs. The most common virus is called the rhinovirus. Other viruses include the coronavirus, parainfluenza virus, adenovirus, enterovirus, and respiratory syncytial virus. Up to 15% of acute pharyngitis cases may be caused by bacteria, most commonly Streptococcus pyogenes a Group A streptococcusin Streptococcal pharyngitis ("Strep Throat"). Other bacterial causes are streptococcus pneumoniae, haemophilus influenzae,corynebacterium diphtheriae, bordetella pertussis, and bacillus anthracis. Probiotics may be useful in preventing URTIs. Vaccination may even help prevent URTIs, mostly against influenza viruses,adenoviruses, streptococcus pneumoniae, haemophilus influenzae, diphtheria, bacillus anthracis, and bordetella pertussis. Treatment depends on the underlying cause. There are currently no medications or herbal remedies which have been conclusively demonstrated to shorten the duration of the illness. Treatment comprises symptomatic support usually via analgesics for headache, sore throat and muscle aches. Moderate exercise in sedentary subjects with naturally acquired URTI probably does not alter the overall severity and duration of the illness. Getting plenty of sleep; however, is advisable since even mild sleep deprivation has been shown to be associated with increased susceptibility to infection. No randomized trials have been conducted to ascertain benefits of increasing fluid intake.
Judicious use of antibiotics can decrease adverse effects of antibiotics as well as decrease costs. But more importantly, decreased antibiotic usage will prevent the rise of drug resistant bacteria, which is now a growing problem in the world. Health authorities have been strongly encouraging physicians to decrease the prescribing of antibiotics to treat common upper respiratory tract infections because antibiotic usage does not significantly reduce recovery time for these viral illnesses. Some have advocated a delayed antibiotic approach to treating URIs which seeks to reduce the consumption of antibiotics while attempting to maintain patient satisfaction. Most studies show no difference in improvement of symptoms between those treated with antibiotics right away and those with delayed prescriptions. Most studies also show no difference in patient satisfaction, patient complications, symptoms between delayed and no antibiotics. A strategy of "no antibiotics" results in even less antibiotic use than a strategy of "delayed antibiotics". However, in certain higher risk patients with underlying lung disease, such as chronic obstructive pulmonary disease (COPD), evidence does exist to support the treatment of bronchitis with antibiotics to shorten the course of the illness and decrease treatment failure. According to a Cochrane review single oral dose of nasal decongestant in the common cold is modestly effective for the short term relief of congestion in adults; however, "there is insufficient data on the use of decongestants in children." Therefore decongestants are not recommended for use in children under 12 years of age with the common cold. Oral decongestants are also contraindicated in patients with hypertension, coronary artery disease, and history of bleeding strokes. The use of Vitamin C in the inhibition and treatment of upper respiratory infections has been suggested since the initial isolation of vitamin C in the 1930s. Some evidence exists to indicate that it could be justified in persons exposed to brief periods of severe physical exercise and/or cold environments. The benefits versus risk of nasal irrigation are currently unclear and therefore is not recommended.
