Respiratory viruses, including coronaviruses, are known to have a high incidence of
infection during winter, especially in temperate regions. Dry and cold conditions during …

In 1981, R. Edgar Hope-Simpson proposed that a 'seasonal stimulus' intimately associated
with solar radiation explained the remarkable seasonality of epidemic influenza. Solar …

In the temperate regions, seasonal influenza virus outbreaks correlate closely with
decreases in humidity. While low ambient humidity is known to enhance viral transmission …

Using the guinea pig as a model host, we show that aerosol spread of influenza virus is
dependent upon both ambient relative humidity and temperature. Twenty experiments …

Antigenic and genetic analysis of the hemagglutinin of∼ 13,000 human influenza A (H3N2)
viruses from six continents during 2002–2007 revealed that there was continuous circulation …

Many viruses are capable of infecting the human respiratory tract to cause disease. These
viruses display various transmission patterns among humans; however, they all share the …

Recent developments in complete-genome sequencing, antigenic mapping and
epidemiological modelling are greatly improving our knowledge of the evolution of human …

Humidity has been associated with influenza's seasonality, but the mechanisms underlying
the relationship remain unclear. There is no consistent explanation for influenza's …

A key question for infectious disease dynamics is the impact of the climate on future burden.
Here, we evaluate the climate drivers of respiratory syncytial virus (RSV), an important …

Background. Although influenza is a vaccine-preventable disease that annually causes
substantial disease burden, data on virus activity in tropical countries are limited. We …
