Hemoptysis, chest pain, conjunctivitis, skin symptoms, or digestive system symptoms such as nausea, emesis, and diarrhea may also indicate COVID-19.	Fever and cough are common.

C, unnecessary detail	Samples are collected by physicians, nurses, and medical technicians at designated locations. Upper respiratory tract sampling is mandatory, while lower respiratory tract sampling is optional for patients with sputum. You may experience discomfort or pain while the sample is being collected. The upper respiratory tract sample is a combination of a nasopharyngeal and oropharyngeal swab in one tube. A nasopharyngeal swab involves inserting a cotton swab into the nostril until it reaches the posterior nares. An oropharyngeal swab includes inserting a cotton swab to scrape the inside of the throat. A lower respiratory tract sample is collected by spitting sputum into a container, ensuring that it is not contaminated by other liquids.
