Rhinovirus infection is influenced by atmospheric conditions and
outdoor-air virus
R
hinovirus are picornavirus with over 150 serotypes and 3 species. Although usually
causing common colds, in Asthma, COPD and elders it may cause life-threatening
disease. Transmission routes may involve human-to-human and indirect transmission. To
the best of our knowledge, no outdoor-air based transmission has been reported.
In the present study we evaluated the role of outdoor and indoor air-borne virus in the
transmission of rhinovirus.
Monthly nasal swabs were collected from 89 volunteers. Weekly outdoor and indoor
air samples were collected. Daily atmospheric parameters were collected from the FP-
ENAS meteorological station and the public air quality monitoring infrastructure. RNA
was purified with Qiagen column-based kits. Viral RNA was quantified by RTqPCR on
Lightcycler 1.1 (Roche).
No indoor-air samples showed rhinovirus. Outdoor air samples showed rhinovirus presence
with a peak in November, closely resembling the frequency of positive nasal samples.
Sun Radiation (p<0.0001), and atmospheric SO2 (R=-0.843; p<0.009) and benzene levels
(R=0.809; p<0.001) were found to significantly relate to the presence of nasal rhinovirus.
Conclusions:
Air-borne rhinovirus correlates with human infection. This may be influenced
by viral stability due to atmospheric conditions. Additionally, immune-system interfering
pollutants such as atmospheric benzene may also influence airborne rhinovirus infectivity.
