Flight passengers complain about maskless coughing on board as summer travel heats up

As summer travel kicks off, many Americans are taking to the skies to reach their destination. 

One traveler is sounding off about the passing around of summer sicknesses, calling out "sick people" with "no masks" - and igniting plenty of debate and input from others. 

"I have lung disease and occasionally I get a coughing fit. I'm not sick or contagious. Could be the case here," suggested one user.

"This is why I always wear a mask on planes because I can't control if other people wear them," commented a Redditor.

One user said, "I carry a mask and wash my hands before (and after) I use the bathroom. I don't trust others to have common sense or minimal decency."

Another person said, "If you go out in public, there will be germs. Accept it. Move on. Protect yourself however you wish. Or stay home."

Another comment read, "Keep your mask on. Take an airborne or other Vitamin C pill. More than likely you won't get sick. Relax and move on. You cannot do anything."

The agency says that wearing a "high-quality" and "well-fitting mask" can be "effective in reducing the transmission of respiratory pathogens."

"Close proximity of passengers increases the risk of person-to-person airborne spread before contaminated air can be removed from the breathing zone and exhausted or filtered," the CDC notes.
