Health News: People transmit the virus to mosquitoes ♦ Why we look at pretty faces ♦ Using copper to prevent the spread of respiratory viruses

Dengue: Asymptomatic people transmit the virus to mosquitoes Scientists have provided proof that people infected by dengue virus but showing no clinical symptoms can actually infect mosquitoes that bite them. It appears that these asymptomatic people -- who, together with mildly symptomatic patients, represent three-quarters of all dengue infections -- could be involved in the transmission chain of the virus.
'Post-hospital syndrome' found to be a risk factor for elective surgery A condition known as 'post-hospital syndrome' (PHS) is a significant risk factor for patients who undergo elective outpatient surgery, a new study has found. PHS is defined as having been hospitalized during the previous 90 days. This first-of-its-kind study found that among patients with PHS, 7.6 percent had to be readmitted to the hospital within 30 days of undergoing elective outpatient hernia surgery.
Why we look at pretty faces Few visual impressions can be compared to humans' interest for faces. New research suggests that our brain rewards us for looking at pretty faces.
Using copper to prevent the spread of respiratory viruses Copper can effectively help to prevent the spread of respiratory viruses, which are linked to severe acute respiratory syndrome (SARS) and Middle East respiratory syndrome (MERS), new research shows. Animal coronaviruses that 'host jump' to humans, such as SARS and MERS, result in severe infections with high mortality. Researchers found that a closely-related human coronavirus - 229E - can remain infectious on common surface materials for several days, but is rapidly destroyed on copper
