It is up to you if you want to go back to work. You could also ask your boss at DHL for advice.
From what you have posted I believe you could return to work if you wanted.
Just for your information:
The classic features for COVID-19 (coronavirus):
59-67% dry cough
40% loss of appetite
14-35% muscle aches
18-31% trouble breathing
27-33% increased phlegm/sputum
14% sore throat
HOWEVER -- some patients have minimal symptoms which can mimic the regular cold or flu (sore throat, diarrhea, runny nose, a low grade fever only)
Please read the USA CDC website for the latest clinical information:
The NHS guidelines ask that you self-isolate for 7 days if you have 1) a fever or 2) a new continuous cough. DO NOT go to your doctor or hospital to get this evaluated UNLESS you have significant difficulty breathing.
If you are over 70 -- staying at home (self isolation) is the best option for now to reduce your potential exposure to the coronavirus.
