Viral fevers usually last about 1 week, with most clearing up in 3-5 days. Viral fever usually presents with a stuffy nose, runny nose, sneezing, and sore throat. Most fevers are low to moderate fever, but some patients present with high fever. Others present with a cough and coughing sputum. If there are symptoms of cough and sputum, it is recommended to take antiviral and cough suppressants. If it is prolonged, it is recommended to go to the hospital to check if there is a combination of bacterial infection. So patients who come to the hospital, especially those with fever, are advised to check their white blood cells and whether their white blood cells are elevated. Because high white blood cells are usually combined with bacterial infection, viral infection white blood cells are generally not high, of course, there are patients with low resistance or some elderly patients may have inflammatory infections, white blood cells may not be high. In terms of treatment, you can usually keep cold medicine, Pancreatin and Pudillan at home. The main thing is to pay attention to keep warm, especially in winter, and in summer most patients will have cold symptoms such as nasal congestion and runny nose after staying in air-conditioned rooms for a long time.
