communicable respiratory diseases: the common cold, influenza, pneumonia,

strep throat, tuberculosis, and SARS. You will learn the causes, methods of transmission,

symptoms, diagnoses and treatments, and prevention for each disease.

What to Know About CommunicableRespiratory Diseases

Communicable diseases

The common cold A respiratory infec-tion caused by more than 100 differ-ent viruses is the One-third of all colds are caused byrhinoviruses. A rhinovirus is a virusthat infects the nose. High levels ofstress can increase a person’schances of catching a cold. Beingexposed to cold weather or gettingchilled does not cause a cold. A coldcan last from 2 to 14 days.

OTC medicines may help relievesome symptoms, but they will notcure or shorten the length of a cold.Gargling with warm salt water maybring relief to a sore throat. Applyingpetroleum jelly to the nose may helpan irritated nose.

Influenza A highly contagious viralinfection of the respiratory tract is

or the flu. Most peoplerecover within a week or two, but it

can be life-threatening for elderly peo-ple, newborn babies, and people withchronic diseases. The flu can lead topneumonia. Flu viruses are constantlychanging, making it difficult for theimmune system to form antibodies tonew variations of the flu virus. Flu canspread rapidly in crowded places. Theinfected person who spreads it oftendoes not show symptoms, yet can stillspread the disease. An infected personis particularly contagious during thefirst three days of infection.

A physician usually determines ifpeople have the flu by their symp-toms and by whether the flu is pres-ent in the community. Aspirin oracetaminophen may relieve fever anddiscomfort.

Children and teens should not takeaspirin to relieve symptoms as it mayincrease the chances of developingReye’s syndrome.

influenza,

common cold.

Make theConnectionDiseases in theUnited States Formore information onthe nation’s healthconcerns, see page 59in Lesson 6.

Reye’s syndrome is a disease thatcauses swelling of the brain and dete-rioration of liver function. Antibioticsare not effective against flu viruses,but may help prevent the pneumoniathat sometimes follows it.

Flu shots are available. Since fluviruses change often, flu vaccines areupdated each year. They are highlyrecommended for people under age 2and/or over age 65; people withchronic illnesses, and/or a history ofrespiratory infections; pregnantwomen who are in their second orthird trimester during flu season;and health-care workers.

Pneumonia An infection in the lungscaused by bacteria, viruses, or otherpathogens is Pneu-monia bacteria and viruses can bespread by direct contact with aninfected person or with contaminatedobjects. Laboratory tests, chest X rays,and physical examinations are usedto diagnose pneumonia. Prompt treat-ment is critical. Antibiotics are usedto treat bacterial pneumonia, butviral pneumonia is much more diffi-cult to treat. Severe cases may requirehospital care. A vaccine is available toprevent pneumococcal pneumonia, atype which kills more people than allother vaccine-preventable diseases.

Strep throat A bacterial infection ofthe throat is If it is nottreated promptly, rheumatic fevercan occur. is anautoimmune disease in the heartthat can cause fever, weakness, anddamage to heart valves. When some-one has strep throat, the throat mayappear very red and small patches ofpus may be visible. A throat cultureis needed to diagnose strep throat.Antibiotics are prescribed to kill thebacteria and to prevent spread of theinfection. Rest and fluids help thebody fight the infection.

Tuberculosis A bacterial infection ofthe lungs is tuberculosis. Peoplewith a weakened immune system,such as those with HIV and the eld-erly, are highly susceptible to tuber-culosis. Those who are homeless,malnourished, or inject drugs are atincreased risk for tuberculosis.

Tuberculosis bacteria become air-borne through coughing and sneezingby an infected person. Only peoplewith active tuberculosis are conta-gious. Tuberculosis is not likely to bespread through items or objects thathave been touched by a person withthe disease.

A tuberculin skin test is the injec-tion of a protein substance under theskin in the forearm. If within twodays a red welt forms around wherethe protein was injected, the personhas been exposed to tuberculosis.This does not confirm that a personhas tuberculosis. Chest X rays andsputum samples are used to confirma diagnosis. Although antibiotics areused to treat tuberculosis, sometuberculosis pathogens have becomeresistant to them. Drugs are avail-able to prevent tuberculosis in people

who are in close contact with infectedpeople. Rooms with good ventilationand air flow reduce the risk of thespread of tuberculosis.

Severe acute respiratory syndrome(SARS) A contagious respiratory illness caused by a new type of coronavirus is SARS. SARS surfacedin early 2003 in some Asian countriesand then caused outbreaks in other

countries. It is important to under-stand that the symptoms of SARSare typical for many other respira-tory illnesses, including a fever,cough, or shortness of breath. Withthis illness, another criterion fordiagnosis is travel to specific Asiancountries where SARS exists and/orclose contact with a person infectedwith SARS. Since the initial out-break, SARS is now under control.

Asthma and ChildrenAsthma is the mostcommon long-termdisease in school-agechildren.

Acondition in which the bronchial tubes become inflamed and

constrict, making breathing difficult for many people, is

. Asthma is an example of a noncommunicable

disease. Noncommunicable diseases are not spread from person to

person. No type of condition results in as much absenteeism in school as asthma.

What to Know About Asthma

asthma

Asthma Asthma is a chronic diseasethat cannot be cured. Symptoms ofasthma include coughing, wheezing,and shortness of breath. People withasthma have sensitive lungs thatreact to certain asthma triggers.Asthma triggers are substances thatcause the airways to tighten, swell,and fill with mucus. The airwaysbecome narrow and blocked, and it isdifficult to breathe.

Asthma triggers include pollenfrom trees; grasses and weeds; dustand mold; dog, cat, or other animaldander; cigarette smoke; air pollu-tion; having a cold or the flu; aspirinor other OTC drugs; perfumes andfragrances; odors from sprays andpaints; insecticides; certain foods;and smoke from burning wood, paper,or other items.

Asthma also can be triggered byemotional stress, especially duringchildhood and adolescence. Asthmaattacks can be very serious.

An asthma attack is an episodeof coughing, wheezing, shortness ofbreath and tightness in the chestexperienced by a person who hasasthma. Some people may becomeextremely sick from asthma attacksand need to be hospitalized, andsome people have died from them.

Most children who suffer fromasthma continue to have asthma asadults. However, for about one-fourthof children with asthma, the symp-toms decrease significantly as theyget older. Sometimes, however,asthma does not develop until a per-son is an adult.

Exercise-induced asthma A conditionin which a person has difficultybreathing during or shortly afterstrenuous physical activity is calledexercise-induced asthma (EIA).The symptoms of EIA can be mild orsevere and include coughing, wheez-ing, shortness of breath, and tight-ness in the chest.

Some people with EIA suffer anasthma attack only with exercise. Ahigh percentage of people with EIAsuffer asthma from allergies to air-borne substances, such as air pollu-tants, dust, and animal dander.Exposure to cold, dry air duringphysical activity is a major trigger.

Six Warning Signs and Symptoms of Asthma

• coughing• wheezing • shortness of breath

• tightness in the chest• rapid breathing• itchy or sore throat

494 UNIT 8 • Communicable and Chronic Diseases

The following are warning signs of an asthma attack:

Since regular physical activityimproves health status, learning tomanage EIA is important. Propermedication allows most people whohave EIA to participate in regularphysical activity. People with EIAfrequently breathe in puffs of med-ication from an inhaler before theyexercise to prevent an EIA attack.

EIA often can be reduced and pre-vented by improving physical fitness.Breathing warm, moist air usuallyhelps the condition. Swimming andother indoor water sports provide anideal environment for people whohave EIA.

Ways to prevent asthma attacksPeople who have asthma can prevent

asthma attacks by avoiding asthmatriggers. For instance, they may avoidsmoky restaurants, refrain from wear-ing perfumes and fragrances, or tradehousehold chores with siblings so thatthey don’t have to do yard work thatcould aggravate their asthma. Otherways of avoiding asthma attacksinclude recognizing warning signs andtaking certain medication. If they failto recognize these signs, their symp-toms may get worse.

If you have asthma, make a planwith your parents or guardian andyour physician about what to do whenyou notice warning signs and symp-toms of asthma. People with asthmashould always carry their medica-tions with them in case of an attack.

Airborne allergens The most commonairborne allergens are animal dander,feathers, pollens, and mites. Animaldander is flakes of dead skin from ananimal. People who have symptoms,such as dizziness, nausea, skin rash,itchy or watery eyes, drops in bloodpressure, or difficulty in breathingwhen they are near cats, dogs, or otheranimals, are allergic to animal dander.

is a yellowish powder pro-duced by flowers, trees, and grass.Pollen may become airborne and trigger an allergic response. The mostcommon response is hay fever.

is a common term for sea-sonal respiratory allergies that typi-cally occur in the spring and fall.Symptoms include coughing, sneez-ing, and inflammation of the nasalmucous membranes. People who havehay fever may take medicine orreceive shots regularly to lessen theirresponse to pollen.

Some people are allergic to housedust because it usually contains smallfragments of mites and their feces.Mites are tiny, eight-legged animalsthat resemble spiders.

Other allergens Not all allergies areairborne. A person can be allergic tomedication, latex, insect stings, orfoods. One medication to which manypeople are allergic is penicillin, an

antibiotic. A person who is allergic topenicillin may experience breathingdifficulties, rapid pulse, and a suddendrop in blood pressure. Other types ofantibiotics can be used to treat diseaseif a person is allergic to penicillin.

People also can have an allergicreaction to latex or an insect sting.Symptoms include skin rash, respira-tory irritation, and in some cases,shock. To avoid a reaction to latex, aperson could use plastic or vinyl gloves.

Many people are allergic to certaintypes of food. Peanuts, eggs, milk, andshellfish are some common food aller-gens. People with food allergiesshould avoid foods that contain theirallergy trigger.

Allergy tests Skin tests can be usedto identify allergens that produceallergic reactions. A skin patch testinvolves putting allergens on a patch,taping the patch to the skin, andobserving the reaction. Another testinvolves using a needle to place aller-gens under the skin and observingthe reaction. A or a roundskin lump, indicates sensitivity to aparticular allergen.

Treating allergies Medications can helpreduce or eliminate the severity of cer-tain reactions. People may need toreceive medication on a regular basis.
