NewsVentilation in hospitals could cause viruses to spread further
Increased use of ventilation and air cleaners, designed to mitigate the spread of viral infections in hospitals, is likely to have unpredictable effects and may cause viral particles to move around more, according to a new study.

NewsResearchers in Brazil discover a gene that may afford protection against COVID-19
During the pandemic, health worker Maria Tereza Malheiros Sapienza’s curiosity was aroused by her immunity to SARS-CoV-2, even though her husband was infected twice. A new study reveals that an overexpression of IFIT3 protein was responsible.

NewsZika uses human skin as ‘mosquito magnet’ to spread virus further
A new study shows that the Zika virus causes metabolic changes in human skin that essentially transforms it from a protective barrier to a magnet for mosquitoes.
