BOSTON (CBS) – Did you know that a sneeze is actually a “high-propulsion” cloud that can rapidly infect a room?
Researchers at the Massachusetts Institute of Technology (MIT) have caught it on video and it may someday help improve infection control.READ MORE: 2 Hanover Street Banks Robbed Within 10-Minute Timeframe
They’ve been studying sneezing for years and the group presented their latest findings this week at a meeting of the American Physical Society in Boston.

This time, they recorded high-speed video of two healthy people sneezing about 50 times over the course of several days.READ MORE: NH Fish And Game To Sell 2022 Calendars Featuring K9 Teams
By digging deeper, they discovered how the droplets are formed – “within a high-propulsion sneeze cloud.” They say that’s a critical piece of the sneeze puzzle that they’ve been missing.
“Droplets are not all already formed and neatly distributed in size at the exit of the mouth, as previously assumed in the literature,” MIT professor Lydia Bourouiba, one of the lead researchers in the study, said in a press release.
Sneezes can spread infectious diseases like measles, influenza or SARS, by suspending those viruses in the droplets. People can breathe in those drops or unknowingly come in contact with them with their hands.
The Centers for Disease Control and Prevention (CDC) says on its website that sneezing and cough “etiquette is especially important for infection control.”MORE NEWS: Boston's Famous 'Skinny House' In The North End Sells For $1.25 Million
