West Nile encephalitis:
Causes and incidence
(Professional Guide to Diseases (Eighth Edition))
WNV is transmitted to humans by the bite of a mosquito (primarily the Culex species) infected with the virus. It's considered the primary vector for WNV and the source of the August 1999 outbreak in New York, New Jersey and Connecticut. Mosquitoes become infected by feeding on birds contaminated with the West Nile virus and then transmitting it to humans and animals during a blood meal or “bite.” (See Transmission routes of West Nile virus, page 256.)
Ticks have been found infected with WNV in Africa and Asia only. The role of ticks in the transmission and maintenance of the virus remains uncertain, and to date they aren't considered vectors for WNV in the United States.
The Centers for Disease Control and Prevention has reported that there is no evidence that a person can contract the virus from handling live or dead infected birds. However, avoid barehanded contact when handling dead animals, including birds, and use gloves or double plastic bags to dispose of a carcass. Report the finding to the local health department.

Inclusion conjunctivitis:
Causes and incidence
(Professional Guide to Diseases (Eighth Edition))
C. trachomatis is an obligate intracellular organism of the lymphogranuloma venereum serotype group. Serotypes D through K are sexually transmitted, and secondary eye involvement in adults occurs in about 1 in 300 genital cases. Because contaminated cervical secretions infect the eyes of the neonate during birth, inclusion conjunctivitis is an important cause of ophthalmia neonatorum. Ocular chlamydial disease occurs most frequently in adults between ages 18 and 30.

Encephalitis:
Causes
(Handbook of Diseases)
Encephalitis generally results from infection with arboviruses specific to rural areas. In urban areas, it’s most frequently caused by enteroviruses (coxsackievirus, poliovirus, and echovirus).
Other causes include herpesvirus, mumps virus, human immunodeficiency virus, adenoviruses, and demyelinating diseases after measles, varicella, rubella, or vaccination.
Between World War I and the Depression, a type of encephalitis known as lethargic encephalitis, von Econ-omo’s disease, or sleeping sickness occurred with some regularity. The causative virus was never clearly identified, and the disease is rare today. Even so, the term sleeping sickness persists and in many cases is mistakenly used to describe other types of encephalitis as well. The most recent outbreak of mosquito-borne encephalitis was West Nile encephalitis.

Ticks infected with WNV have been found in Africa and Asia, but their role in transmission and maintenance of the virus is uncertain; they aren’t considered vectors for WNV in the United States.
The Centers for Disease Control and Prevention has reported that there’s no evidence that a person can contract the virus from handling live or dead infected birds. However, barehanded contact when handling dead animals, including dead birds, should be avoided; if a dead animal must be handled, gloves or other protective measures should be used to dispose of the carcass. A dead bird is a sign that there may be infected mosquitoes in the area; findings should be reported to the nearest Emergency Management Office.

Inclusion conjunctivitis:
Causes
(Handbook of Diseases)
C. trachomatis is an obligate intracellular organism. It usually infects the urethra in males and the cervix in females and is transmitted during sexual activity.
Because contaminated cervical secretions infect the eyes of the neonate during birth, inclusion conjunctivitis is an important cause of ophthalmia neonatorum. Rarely, inclusion conjunctivitis results from autoinfection, by hand-to-eye transfer of the organism from the genitourinary tract.

Encephalitis:
Encephalitis - pathophysiology
(The 5-Minute Pediatric Consult)
- Direct or delayed (postinfectious) reaction by the immune system to a virus, bacteria, fungus, or parasite
- Organisms enter the CNS via the systemic circulation, direct inoculation (trauma), or neural pathways (rabies, herpes simplex virus [HSV]).
- Infiltration/activation of inflammatory cells in the CNS with release of cytokines
- Inclusion bodies (intranuclear, HSV, subacute sclerosing panencephalitis [SSPE], viral, intracytoplasmic, rabies); CSF; and serological changes
Encephalitis - etiology
- The most common causes of encephalitis are viruses:
- Summer (enteroviruses)
- Summer and fall (western and eastern equine, St. Louis, La Crosse, and West Nile encephalitis)
- Winter (varicella)
- Nonviral causes (tuberculosis, Lyme disease, toxoplasmosis, cat scratch disease, rickettsial disease, tick-borne infections) are sometimes associated with specific environmental or geographic exposure.
- The most common cause of sporadic encephalitis is HSV (rabies and HIV also occur in all seasons).

Measles (Rubeola, First Disease):
Measles - pathophysiology
(The 5-Minute Pediatric Consult)
Transmission of measles is thought to occur mainly by microaerosolized droplets of respiratory secretions.
Measles - etiology
- Measles is a paramyxovirus, genus Morbillivirus.
- 1st isolated in 1954 in human and monkey kidney tissue cultures
