This document defines communicable diseases and provides information on several specific diseases including chickenpox, measles, mumps, polio, pertussis, AIDS, dengue, tetanus, typhoid fever, cholera, and rabies. It describes the causative agents, signs and symptoms, treatment, nursing management, and prevention for each disease.
A home visit is one of the essential parts of the community health services because most of the people are found in a home. Home visit fulfils the needs of individual, family and community in general for nursing service and health counselling. A home visit is considered as the backbone of community health service. A home visit is a family –nurse contact which allows the health worker to assess the home and family situation in order to provide the necessary nursing care and health-related activities.
Immunization, or immunisation, is the process by which an individual's immune system becomes fortified against an infectious agent (known as the immunogen).

Measles is an acute respiratory viral infection, contagious in nature. It may lead to epidemic if susceptible population is more than 40%. But with very effective vaccine, it can be eliminated
Measles is a highly infectious disease of childhood caused by Measles virus. It is characterized by fever, catarrhal symptoms of the upper respiratory tract infections followed by typical rash.
Measles is defined as an acute and highly contagious viral disease characterized by fever, runny nose, cough, red eyes and a spreading skin rash.
Causative agent: Rubeola virus, a RNA virus of paramyxoviridae family
Reservoir: Human
Source: Infected Human
Period of Communicability: Approximately 4 days prior and 4 days after the appearance of the rash
Mode of Transmission:
Airborne transmission(virus remains active and contagious in the air or on infected surfaces for up to 2 hours)
Droplet transmission i.e. it is spread by coughing and sneezing, close personal contact or direct contact with infected nasal or throat secretions
Portal of entry: Respiratory tract and Conjunctiva
Incubation Period: 10-15 days
Host:
Children between age of 1 and 5 years
Older children
Malnourished children
Environment: Winter and spring month ,Low socio-economic status .
Clinical manifestations of measles are in three stages:
STAGE 1: Prodromal/ Catarrhal Stage:
starts after 10 days of infection and lasts up to 3-5 days-
- Fever
- Malaise
- Coryza
- Sneezing
- Nasal Discharge
- Brassy Cough
- Redness of eye
- Lacrimation
- Photophobia
- Lymphadenopathy
- Vomiting
- Diarrhea
- Koplik spot – grayish or bluish white spots, fine tiny grain like papules on a faint red base, smaller than the head of pin.
- Spots appear before the appearance of rash
- Found on buccal mucosa opposite to first and second molar
- Usually disappear after the rash, appears a day
Stage 2: Eruptive Stage:
- Typical irregular dusky red macular or maculopapular rash found behind the ears and face first, usually 3-5 days after the onset of disease
- Then it spread to neck, trunk, limbs, palms and soles in the next 3-4 days.
- Anorexia
-Malaise
-Cervical lymphadenopathy
-Fever and rash usually disappear in 4-5 days in the same order of appearance
- Fine shedding of superficial skin of face, trunk and limbs leaving brownish discoloration that persists 2 months or more
Stage 3: Convalescent or Post- Measles Stage:
-Fever and rash disappear
-Child remains sick for number of days and lose weight
- Gradual deterioration into chronic illnesses due to bacterial or viral infections, nutritional and metabolic disturbances or other complications.
prevention- Active Immunization with live attenuated vaccines 0.5 ml subcutaneously in single dose at 9-12 months of age.

21. ACQUIRED IMMUNO DEFICIENCY SYNDROME:
Introduction:
Epidemiology:
– 2.3 million children are living with HIV.
– 18% of children are died because of HIV infection.
– 4% children are in ARV therapy.
– India, thailand, myanmar, indonesia are HIV affected regions.
HIV IN INDIA:
One third of children will die by their 1st birthday.
More than half of the children will die by the age of 2 years.
AP, karnataka, maharastra, manipur , nagaland, TN bear this burden.
22. MODE OF TRANSMISSION:
– Sexual, mucosal, blood, semen, and vaginal fluids.
– In India, spread in adults through heterosexual intercourse.
– Sexually abused children are also at high risk of HIV infection.
– Drug use, infected needles.
– Commonly from perinatally from an infected mother to her infant.
PATHOPHYSIOLOGY:
• HIV virus infects T lymphocytes, CD4 T cells
• The virus takes over CD4 cells and reduce the cell function.
• The CD4 count decreases leads to immunodeficiency.
• The count reaches the low level and cause illness followed by death.
24. DIAGNOSTIC EVALUATION:
• Serological tests
and
• Virology tests.
GENERAL CARE:
– Immunization,
– Anti retro viral therapy,
– Prevention of pediatric HIV,
– Prevention of mother to child transmission(ante, intra, post natal),
– Immediate new born care.
