Based on information from the US Public Health Service (USPHS) and Centers for Disease Control and Prevention (CDC), Apple's virtual assistant Siri is providing advice to people who are concerned whether they might have coronavirus. Users can ask Siri questions such as 'How do I know if I have coronavirus?' or 'Do I have coronavirus?' and it will offer advice based on their symptoms. People with extreme symptoms are advised to call 911, while those not sure if they have the disease are informed of the symptoms and told to self-isolate if they appear.
