VIROLOGY URTs
Why common?
Large volume in RT
• Respiratory tract>> large surface area
• Respiratory viruses>>High quantity
• Viruses>everywhere in the world
• all year+ seasonal (winter)

Aetiology
Respitaory Viruses
Affects mainly respiratory tract
Classic respiratory viruses
Orthomyxoviruses
Paramyxoviruses
Rhinovirus 1 to ±100
oFTEN CHILDREN
TRANSMISSION OF RTI
Droplets>>Large/medium/small
fomites>> Substances contaminated with infection
Airborne/aerosol
Resp. infections in winter
Viruses=underground work
2ndary bacterial infection invasion
Same organism>>different syndromes
Same syndrome>different organisms
RTI in children
Immature immunity:↑ viruses/serotypes
Viral evolution>>emerging of new strains
Why we keep getting infections: poor immunity, Viral
evolution,↑ viruses/serotypes
