Diphtheria
an upper respiratory tract illness characterized by sore throat,
low fever, and an adherent membrane (a pseudomembrane) on the tonsils, pharynx, and/or
nasal cavity
![Page 3: Infectious Diseases](https://reader035.vdocuments.net/reader035/viewer/2022062323/5695d3cf1a28ab9b029f46b8/html5/thumbnails/3.jpg)
causes the progressive deterioration of myelin sheaths in the central
and peripheral nervous system leading to degenerating motor control and
loss of sensation.

a contagious disease spread by direct physical contact or breathing the aerosolized secretions of infected
individuals
![Page 5: Infectious Diseases](https://reader035.vdocuments.net/reader035/viewer/2022062323/5695d3cf1a28ab9b029f46b8/html5/thumbnails/5.jpg)
Schick test
• test used to determine whether or not a person is susceptible to diphtheria
• named after its inventor, Béla Schick (1877–1967), a Hungarian-born American pediatrician
![Page 6: Infectious Diseases](https://reader035.vdocuments.net/reader035/viewer/2022062323/5695d3cf1a28ab9b029f46b8/html5/thumbnails/6.jpg)

Nursing Diagnosis
• Risk for infection
• Knowledge deficit
• Altered body temperature
• Altered comfort:pain (sore throat)
• Risk for altered breathing pattern
• Risk impaired gas exchange
![Page 8: Infectious Diseases](https://reader035.vdocuments.net/reader035/viewer/2022062323/5695d3cf1a28ab9b029f46b8/html5/thumbnails/8.jpg)
Nursing Interventions
• Encourage the patient and significant others to avoid contact with infected individuals
• Educate the public
• Encourage compliance to treatment regimen
![Page 9: Infectious Diseases](https://reader035.vdocuments.net/reader035/viewer/2022062323/5695d3cf1a28ab9b029f46b8/html5/thumbnails/9.jpg)
Treatment
in more severe cases lymph nodes in the neck may swell, and breathing and swallowing will be more difficult. People in this
stage should seek immediate medical attention, as obstruction in the throat may require intubation or a tracheotomy. Abnormal
cardiac rhythms and can occur early in the course of the illness or weeks later, and can lead to heart failure. Diphtheria can also cause paralysis in the eye, neck, throat, or respiratory muscles.
Patients with severe cases will be put in a hospital intensive care unit (ICU) and be given a diphtheria anti-toxin.
Since antitoxin does not neutralize toxin that is already bound to tissues, delaying its administration is associated with an
increase in mortality risk. Therefore, the decision to administer diphtheria antitoxin is based on clinical diagnosis, and should
not await laboratory confirmation.
![Page 10: Infectious Diseases](https://reader035.vdocuments.net/reader035/viewer/2022062323/5695d3cf1a28ab9b029f46b8/html5/thumbnails/10.jpg)
•
Erythromycin (orally or by injection) for 14 days (40 mg/kg per day with a maximum of 2 g/d), or
Procaine penicillin G given intramuscularly for 14 days (300,000 U/d for patients weighing <10 kg and
600,000 U/d for those weighing >10 kg). Patients with allergies to penicillin G or erythromycin can use
rifampin or clindamycin
![Page 11: Infectious Diseases](https://reader035.vdocuments.net/reader035/viewer/2022062323/5695d3cf1a28ab9b029f46b8/html5/thumbnails/11.jpg)
Pertussis
![Page 12: Infectious Diseases](https://reader035.vdocuments.net/reader035/viewer/2022062323/5695d3cf1a28ab9b029f46b8/html5/thumbnails/12.jpg)
bacterial infection of the respiratory tract. It is also called "whooping cough.“
Pertussis is a very contagious disease of the
mucous membranes that line the air passages
![Page 13: Infectious Diseases](https://reader035.vdocuments.net/reader035/viewer/2022062323/5695d3cf1a28ab9b029f46b8/html5/thumbnails/13.jpg)
spread easily from person to person. People get Pertussis by breathing in
airborne droplets expelled from the nose or throat of an infected person.
Despite an effective vaccine, Pertussis continues to cause serious illness and
death. Young children are most at risk for
Pertussis, but the disease is increasing in adolescents and adults.
![Page 14: Infectious Diseases](https://reader035.vdocuments.net/reader035/viewer/2022062323/5695d3cf1a28ab9b029f46b8/html5/thumbnails/14.jpg)
caused by Bordetella Pertussis, a bacterium
![Page 15: Infectious Diseases](https://reader035.vdocuments.net/reader035/viewer/2022062323/5695d3cf1a28ab9b029f46b8/html5/thumbnails/15.jpg)
s/sx: Cold, including sneezing, runny nose, low-grade fever, and a mild cough. Within 2 weeks, the
cough becomes much worse. Children with pertussis often have episodes of rapid, spasmodic
coughing followed by a characteristic intake of breath that sounds like a "whoop." The violent
coughing spells are worse at night and can last for as long as 1 to 2 months
The spells can make it hard for a child to eat, drink, or even breathe. Infants under age 6 months, adolescents, and adults generally have milder
symptoms without the typical whoop.
![Page 16: Infectious Diseases](https://reader035.vdocuments.net/reader035/viewer/2022062323/5695d3cf1a28ab9b029f46b8/html5/thumbnails/16.jpg)
Nursing Diagnosis
• Risk for infection
• Knowledge deficit
• Altered body temperature
• Altered comfort:pain (sore throat)
• Risk for altered breathing pattern
• Risk impaired gas exchange
![Page 17: Infectious Diseases](https://reader035.vdocuments.net/reader035/viewer/2022062323/5695d3cf1a28ab9b029f46b8/html5/thumbnails/17.jpg)

![Page 18: Infectious Diseases](https://reader035.vdocuments.net/reader035/viewer/2022062323/5695d3cf1a28ab9b029f46b8/html5/thumbnails/18.jpg)
Treatment
Treated with antibiotics. Infected persons can still spread the disease until 5 days after treatment begins
The most important way to prevent pertussis is through complete
immunization.
![Page 19: Infectious Diseases](https://reader035.vdocuments.net/reader035/viewer/2022062323/5695d3cf1a28ab9b029f46b8/html5/thumbnails/19.jpg)

Signs & Symptoms
painful spasms of the muscles. The first sign is often "lockjaw", caused by a spasm of the masseter muscle.
Other early signs are headache, difficulty swallowing, neck stiffness,
irritability, and restlessness
![Page 21: Infectious Diseases](https://reader035.vdocuments.net/reader035/viewer/2022062323/5695d3cf1a28ab9b029f46b8/html5/thumbnails/21.jpg)

Poliomyelitis
acute viral infectious disease spread from person to person, primarily via
the fecal-oral route
genus Enterovirus known as poliovirus
![Page 24: Infectious Diseases](https://reader035.vdocuments.net/reader035/viewer/2022062323/5695d3cf1a28ab9b029f46b8/html5/thumbnails/24.jpg)
Pathophysiology
A blockage of the lumbar anterior spinal cord artery due to polio
(PV3)
![Page 25: Infectious Diseases](https://reader035.vdocuments.net/reader035/viewer/2022062323/5695d3cf1a28ab9b029f46b8/html5/thumbnails/25.jpg)

![Page 26: Infectious Diseases](https://reader035.vdocuments.net/reader035/viewer/2022062323/5695d3cf1a28ab9b029f46b8/html5/thumbnails/26.jpg)
Prognosis
Patients with abortive polio infections recover completely
![Page 27: Infectious Diseases](https://reader035.vdocuments.net/reader035/viewer/2022062323/5695d3cf1a28ab9b029f46b8/html5/thumbnails/27.jpg)
Treatment
A modern negative pressure ventilator (iron lung)
used to artificially maintain respiration during an acute polio infection until a person could breathe independently
(generally about one to two weeks
![Page 28: Infectious Diseases](https://reader035.vdocuments.net/reader035/viewer/2022062323/5695d3cf1a28ab9b029f46b8/html5/thumbnails/28.jpg)
Continuation..
• There is no cure for polio. The focus of modern treatment has been on providing relief of symptoms, speeding recovery and preventing complications. Supportive measures include antibiotics to prevent infections in weakened muscles, analgesics for pain, moderate exercise and a nutritious diet. Treatment of polio often requires long-term rehabilitation, including physical therapy, braces, corrective shoes and, in some cases, orthopedic surgery.

Complications of Mumps
The most important is perhaps the brain (encephalitis), which is fatal in 2% of
cases. Infection of the testes (orchitis) in boys can lead to sterility. The
pancreas, kidneys, joints, thyroid, heart, ears, and eyes are also affected
sometimes.

your child will develop an itchy rash consisting of small red bumps that start on the scalp, face and trunk and then spread to the arms and legs (but may also occur in the
mouth and genitalia). The bumps then become blisters with clear and then cloudy
fluid, and then become open sores and finally crust over within about twenty four
hours, but your child will continue to get new bumps for about four more days

Nursing Diagnosis
• Altered comfort pain: headache, joint pains, abdominal pain
• Risk for auditory impairment: hearing loss
• Altered nutrition: less than body requirements r/t decreased appetite
• Risk for visual impairment

Pharmacology
• Antihistamines to reduce itching (taken by mouth or applied to the skin)
• Pain medicines
• Zostrix, a cream containing capsaicin (an extract of pepper) to prevent post-herpetic neuralgia

Nursing Responsibilities
• Cool wet compresses can be used to reduce pain. Soothing baths and lotions, such as colloidal oatmeal bath, starch baths, or calamine lotion, may help to relieve itching and discomfort.
• Resting in bed until the fever goes down is recommended.
• The skin should be kept clean, and contaminated items should not be reused. Nondisposable items should be washed in boiling water or otherwise disinfected before reuse. The person may need to be isolated while lesions are oozing to prevent infection of others -- especially pregnant women.

Outlook (Prognosis)
usually clears in 2 to 3 weeks and rarely recurs. If the virus affects the nerves that control movement (the motor nerves),
you may have temporary or permanent weakness or
paralysis

Prevention
• Avoid touching the rash and blisters of persons with shingles or chickenpox if you have never had chickenpox or the chickenpox vaccine.
• The chickenpox vaccine may be recommended for teenagers or adults who have never had chickenpox. Medical evidence has shown that older adults who receive the vaccine are less likely to have complications from shingles. Adults older than 60 should receive the vaccine as part of routine medical care.

KEY FACTS
• Dengue is a mosquito-borne infection that causes a severe flu-like illness, and sometimes a potentially lethal complication called dengue hemorrhagic fever.
• Global incidence of dengue has grown dramatically in recent decades.
• About two fifths of the world's population are now at risk.
• Dengue is found in tropical and sub-tropical climates worldwide, mostly in urban and semi-urban areas.

Continuation..
• Dengue hemorrhagic fever is a leading cause of serious illness and death among children in some Asian countries.
• There is no specific treatment for dengue, but appropriate medical care frequently saves the lives of patients with the more serious dengue hemorrhagic fever.
• The only way to prevent dengue virus transmission is to combat the disease-carrying mosquitoes.

Nursing Diagnosis
• Risk for infection
• Knowledge deficit
• Risk for altered peripheral tissue perfusion
• Risk for altered body temperature
• Risk for fluid volume deficit
• Altered comfort: abdominal pain r/t gastrointestinal irritation

Prevention and control
![Page 85: Infectious Diseases](https://reader035.vdocuments.net/reader035/viewer/2022062323/5695d3cf1a28ab9b029f46b8/html5/thumbnails/85.jpg)
Continuation..
• Vector control is implemented using environmental management and chemical methods. Proper solid waste disposal and improved water storage practices, including covering containers to prevent access by egg-laying female mosquitoes are among methods that are encouraged through community-based programmes.
• The application of appropriate insecticides to larval habitats, particularly those that are useful in households, e.g. water storage vessels, prevents mosquito breeding for several weeks but must be re-applied periodically. Small, mosquito-eating fish and copepods (tiny crustaceans) have also been used with some success.
