Penyakit Infeksi berdasar Sistem
Infeksi Multi-sistem
• Vector-borne
• Zoonosis
• Fever of Unknown Origin (FUO)
• Infection of the compromised host
Vector Borne Disease
• Arboviruses are arthropod-borne viruses
• Arbovirus replicate in: – Vascular endothelium
– CNS
– Skin and Muscle
• Arbovirus infection: – Yellow fever
– Dengue fever
– Arbovirus encephalitis
– Arbovirus and hemorrhagic fever
Yellow Fever
• Yellow fever virus is transmitted by mosquitoes and is restricted to Africa, Central and South America and the Caribbean
• Clinical features of yellow fever may be mild, but liver damage can prove fatal
• The diagnosis is usually clinical, there is no specific treatment, but there is a vaccine
Dengue Fever
• Dengue virus is transmitted by mosquitoes
and occurs in southeast Asia, the Pacific
area, India and the Caribbean
• Dengue fever may be complicated by
dengue hemorrhagic fever shock
syndrome
• There is no antiviral therapy or vaccine for
dengue fever
Arbovirus Enchephalitis
• The encephalitic arboviruses only
occasionally cause encephalitis
Arboviruses and hemorrhagic fevers
Zoonosis
• Some multisystem infections in man
are animal diseases (i.e. zoonoses)
• Viral Haemorrhagic Fever caused by:
– Arenaviruses
– Filoviruses
– Bunyaviruses
– Flaviviruses
ARENAVIRUS INFECTIONS
• Arenaviruses are transmitted to humans in rodent excreta
• Arenavirus infection is diagnosed by serology, virus isolation or viral genome detection
• Lymphocytic choriomeningitis virus occurs worldwide
• Lassa fever virus is an arenavirus that infects a bush rat in parts of west Africa
KOREAN HEMORRHAGIC FEVER
• The Hantaan virus causes Korean
hemorrhagic fever and infects rodents

SMALLPOX atau VARIOLA
MORBILLI atau MEASLES (RUBEOLA)
Koplik’s spots
MORBILLI atau MEASLES (RUBEOLA)
• Measles outbreaks occur every few years in unvaccinated populations
• Clinical features of measles include respiratory symptoms, Koplik's spots and a rash
• Measles rash results from a cell-mediated immune response
• Complications of measles are particularly likely among children in developing countries
• Measles is usually diagnosed clinically; there is no antiviral treatment, but there is a vaccine
RUBELLA (GERMAN MEASLES)
• Rubella virus infection causes a
multisystem infection, but its main impact
is on the fetus
• Rubella is diagnosed serologically; there is
no treatment, but there is a vaccine
