Sneeze germs travel 4 metres, last for 45 mins: Study

Australia-based researchers have recently found that pathogens when coughed or sneezed into air, travel up to 4 metres and remain alive for 45 minutes. Further study found cough droplets dried up in varying time spans as they hit the air. While most bacteria had a 10-second half-life, some had a half-life of over 10 minutes, risking airborne infection in humans.
