Introduction The cold is very fierce, how to distinguish viral and bacterial colds? Know it in one article! Cold is a general term for upper respiratory tract infection in the folks, because no matter what kind of microorganisms infect the upper respiratory tract, there may be symptoms of sore throat, fever, sneezing, runny nose, cough and sputum.
In real life, common pathogens that cause upper respiratory tract infections include: common cold virus, influenza virus, bacteria and mycoplasma.
So how to distinguish which kind of microbial infection a patient's cold is? Today I will explain this problem through 4 cases.
Case 1: A patient with a cold caused by a common cold virus infection had sneezing and runny nose two days ago, accompanied by an uncomfortable throat, a little body fatigue, but no fever, no body aches, and occasionally coughing and unobvious sputum.
Here are the results of his test: Look at his test results, no white blood cells, neutrophils and their proportions have not increased.
The influenza virus test is also negative, but the adenovirus antibody is positive, indicating an adenovirus infection.
Adenovirus is one of the common cold viruses.
Therefore, this person is a common cold.
For treatment, it is recommended to sleep more and drink plenty of water, and usually heal by itself in about a week.
Case 2: A cold patient caused by bacteria had a sore throat and fever two days ago.
The highest body temperature was 38°C.
There was no sneezing or runny nose, no obvious cough or sputum.
After taking common cold capsules at home for two days, he felt the effect.
Not obvious.
The following is his test result: Everyone sees his laboratory results suggest that: white blood cells, neutrophils and their proportions have increased significantly, C-reactive protein has also increased significantly, five items of respiratory virus are negative, and influenza is also negative.
The performance of a typical bacterial infection.
Therefore, considering that this person has a bacterial infection, antibiotics are recommended for treatment.
Case 3: Mycoplasma infection patient developed uncomfortable throat 3 days ago and took self-medicine for common cold.
Consciously started coughing and sputum production 1 day ago, and coughing was severe at night, which affected falling asleep.
No fever.
The following is the examination report of this patient: Look at the laboratory results of this patient: white blood cells, neutrophils and their proportions are not high, but mycoplasma antibodies are positive, combined with his severe cough symptoms, suggesting mycoplasma infection.
After mycoplasma infection, most people have a more severe cough, and some people have a cough that lasts for a long time.
Therefore, azithromycin or levofloxacin is recommended for treatment.
Note that children, pregnant women and breastfeeding women cannot take levofloxacin orally.
Case 4: Influenza patient developed fever 2 days ago, the highest temperature is 39.
4℃, accompanied by body aches and headaches, accompanied by general weakness, and the effect of self-administered cold medicine is not good.
Look at his test results: white blood cells, neutrophils and their proportions are not high, the flu test showed negative for influenza A, and positive for influenza B.
Combined with the symptoms of high fever and body aches, it can be considered that the diagnosis of influenza B virus infection can be clear.
.
For treatment, it is recommended to take 75 mg of oseltamivir orally twice a day, a course of treatment for five days, and usually heal on its own in about a week.
