Do you have the proper supplies to protect yourself from TB, etc. I think the air filtration may filter out TB, but I am not sure.
I’m starting to worry about that. One is beginning to cough.
As many as 15 percent of U.S. commercial airlines that carry more than 100 passengers lack HEPA filters. And there are currently no standards or regulations that enforce filtration. Even though cabin air is exchanged through the system about 20 to 30 times per hour, there remains a risk, albeit minor, of airborne disease transmission. But who exactly is at risk of infection? And what are they at risk of catching?
Risk of transmission
Generally speaking, your risk of airborne disease transmission depends on how close you’re seated to an infected individual. A safe distance of at least two rows during an eight-hour flight was traditionally assumed sufficient, but this estimate came from studies on the spread of tuberculosis, a contagious bacterial infection of the lower lungs. When a single passenger with severe acute respiratory syndrome (SARS), a viral respiratory infection, infected 22 fellow passengers on a flight from Hong Kong to Beijing back in 2003, researchers realized that passengers as far away as seven rows were at risk.While increasing ventilation can help to decrease the risk of airborne transmission to nearby passengers, the greater risk of infection comes not necessarily from the air, but from direct contact. Diseases like influenza, for example, are more likely to be contracted when someone coughs or sneezes directly on or near you or when you touch an infected surface and then touch an entry pathway on the body, like the eyes or mouth. In many respects, then, airplanes are not much different than other forms of public transportation, like buses or trains. Washing your hands and avoiding touching your face will therefore help to further prevent disease above and beyond proper air filtration.
