Below is an instruction that describes a task. Write a response that appropriately completes the request. ### Instruction: I have been experiencing fatigue lately: my RHR is higher (~55 instead of ~45-50); I get really tired when I try to run, even though I am a runner that does 50 mpw; I feel dizzy for a few seconds when I stand; etc. I have felt fatigued for the past 5-10 days and none of the other symptoms of COVID-19 have appeared. I think the fatigue is potentially from not being as hydrated as usual, the weather getting warmer, or my different eating habits with this whole quarantine situation.However, I am worried that it could be COVID-19. I am wondering what the actual chances of this being COVID-19 are; how many people actually only get fatigue without any of the other symptoms? I get the FAQ states any of the symptoms should be conservatively assumed to be COVID-19 but I am looking for a more statistical response. Thank you!. ### Response: Sorry I am unable to give a statistical response based on your vague set of symptoms..
