How Is Viral Cold Diagnosed?
There are many reasons for catching a cold, such as blowing a cold, infecting viruses, etc., which can be divided into anemofrigid and wind-heat cold and viral flu according to the difference of causes. Although the symptoms are relatively similar, there are also subtle differences. Patients should pay attention to clarify the type of cold according to their symptoms so that the medication can be more instructive and targeted.
Viral influenza is a common respiratory infectious disease caused by a variety of viruses. Incentives include cold, rain, fatigue, malnutrition, and so on. Mainly manifested as sneezing, nasal congestion, runny nose, dry throat, sore throat, cough, hoarseness, and other symptoms. Manifested as headache, body aches, fatigue, loss of appetite, and other symptoms. Mode of Transmission: Sneezing, coughing, and talking spread the virus into the air and infect others. Healthy people can also get sick by using the patient's towels, washbasins, or tableware to infect the virus.
Diagnosis is easier when a cold is prevalent, based on: contact history and collective disease history. Typical symptoms and signs. Sporadic cases are not easy to diagnose. If there are more patients with upper respiratory tract infections in the unit in a short period, the possibility of influenza should be considered and further examination should be carried out to confirm.
In the United States, 200,000 patients are hospitalized each year due to influenza, and 36,000 people die. However, when the patient goes to the hospital, even if the symptoms are very similar to "the flu", it is difficult for the doctor to diagnose "the flu", and can only diagnose a "flu-like case". By definition, an "influenza-like illness" can be diagnosed as long as the body temperature (armpit temperature) is greater than 38°C, accompanied by at least one respiratory symptom (such as sore throat, cough, etc.). However, the diagnosis of "influenza" requires "etiological diagnosis", including the cultivation of the influenza virus or the detection of influenza virus antigens from respiratory specimens. At present, most general hospitals cannot pathogenic detection.
In addition to symptoms such as nasal congestion, headache, sneezing, runny nose, and sore throat, viral colds can also cause fever due to virus invasion. Patients should pay attention to reducing fever. Physical methods can be used to reduce temperature to help the body reduce fever.
