@rby Hello, I will recommend you to visit a doctor and take the prescribed test. It could be anything because the symptoms are almost similar. Most often the usual flu strains come with respiratory symptoms but there are many viruses out there that can produce these same symptoms. Some of the primary symptoms to look for in a Covid 19 infected person are fever, dizziness, breathlessness, headache, dry cough ( eventually resulting in phlegm) and in a few cases loss of smell and taste. A few cases have also reported diarrhea and fatigue. If you develop more serious symptoms you should definitely see a doctor, it is better to take a test. Thanks.
