Colds and fevers are also known as upper respiratory tract infections, so you can consult the respiratory medicine department of the hospital. Routine blood tests and C-reactive protein tests are needed, and a chest X-ray should be taken if there is a cough. If there is a bacterial infection, antibiotics should be used. Viral infections do not cause elevated blood counts, and antiviral medications are the mainstay of this type of cold. During treatment, you should drink plenty of water, at least 2,000 ml a day, and eat plenty of vegetables and fruits to replenish vitamin C. During treatment, you should pay more attention to rest and avoid overwork. The treatment period for colds is 5-7 days, mainly taking oral medicines. In the case of more severe colds, infusion treatment may be required.
