Why 100.4 degrees Fahrenheit?

[olds442jetaway]

Did you ever wonder why you will be denied admission to a casino to play your favorite vp game at that number or higher? The vast majority of the world uses the Celsius scale. They go by 37 degrees being normal and 38 degrees is a fever. If the casinos used anything less than 100.4 F, it would still be 37 C. Why US casinos don’t just ignore the rest of the world and use say 99.9 F is beyond me. To me, you start feeling crappy around that 99.9 number. Maybe they are taking into account hayfever or other things that can cause a mild fever, but what I really think is they want to let as many people in as possible. At any rate, 100.4 F is what they are using.
Not that anybody cares, but to convert Celsius to Fahrenheit, multiply the Celsius reading by 1.8 and add 32. So a reading of 37 degrees Celsius would be 98.6 degrees Fahrenheit and a reading of 38 degrees Celsius would be 100.4 degrees Fahrenheit.

Generally, a temperature of 100.4 or higher means a person has an infection. I'm sure that is why they use that as a baseline.

The numbers are all over the place for different states and businesses. Anywhere from 99.5 to 100.4. In Wuhan, 44 percent of the people that went to the hospital with covid 19 infections, had a fever of 99.5 or higher. That is the standard Deleware uses 99.5 as far as I know and the most strict. The 100.4 number was chosen by so many places because that is the exact number where the Celsius temp changes from 37 degrees to 38.

100.4F (38C) is way too high imo, especially with "contactless thermometers". If I am over 99F with an under the tongue thermometer, I am running a fever. My "normal" is about 97.3F.

I'd say 99.5F (37.5C) should be the cutoff for ADULTS.

Agree Vman. 97.3 is my normal too and that is the reading they get for me in the casino as I walk in. Hayfever will raise it a bit, but like you once I’m in the mid 99s, I know I’m off. They chose that 100.4 number to march 38 celsius. Too high.

100.4F is the high of the normal temperature range for infants and young children. 99 - 99.5F is normal high for adults (depending upon who you ask). However, some medications, such as antibiotics and drugs used to treat high blood pressure or seizures, and certain inflammatory conditions such as rheumatoid arthritis (medicines many seniors take and conditions many have) and heat exhaustion, will raise one's body temperature according to the Mayo Clinic. Anything over 38C (100.4F) "most often means you have a fever caused by an infection or illness" (the quote is from the US National Library of Medicine, Medline Plus Webpage).

Casinos are on a mission to recover lost revenue regardless of cost, however common sense would tell anyone with a fever to stay home instead of going to a casino and possibly getting others sick.

Gamblers won’t though. I know Mohegan Sun just blocked someone that tried to get in with a fever of 104 plus. Hope someone took him to the hospital.
