Fever and very high fever
Yellow fever can develop without any noticeable symptoms. One of the less severe signs that you should be aware of is fever. Don't assume anything is wrong, however, if you or your child has a higher-than-average body temperature but no other signs of sickness. The temperature of a person varies during the day and is affected by different everyday activities and emotions. If an adult develops a fever over 105°F (40.5°C) and it does not go away with treatment, it is a medical emergency that could be hazardous to life, and you should call 911.
