What are the main sources of indoor viruses and bacteria?

Bacteria are everywhere in our daily lives. There are certain bacteria in the air and dust. When we touch other objects in our lives, we are also easily infected with some bacteria. Indoor viruses and bacteria are better places to reproduce. Generally, the main sources of viruses and bacteria are furniture and indoor air quality. People walking around will also easily emit bacteria.

1. Main sources of indoor bacteria and viruses

The increase in bacteria is directly related to the decrease in the amount of negative ions, because negative ions have the effect of inhibiting bacteria. According to a test conducted in an air-conditioned room, the amount of floating bacteria in the room air decreased by 54.94% within 30 minutes after using negative ion products, and decreased by 85.37% within 1 hour of starting up. As time goes by, the sterilization rate stabilizes between 85% and 92%. The mechanism of action of negative ions is to reverse the electrical polarity of the bacterial protein surface, inhibit bacterial growth, and ultimately cause bacterial death without proliferation.

The role of negative ions, whether in hospitals, homes, or public places, is worthy of recognition and has scientific basis. Compared with ultraviolet rays, the disinfection effect is similar, but it is safer and has very obvious effects on other indoor air pollutants. When purchasing related products, you should pay attention to whether the products contain ozone, static electricity and other pollutants that are harmful to the human body.

2. What are the symptoms of viral infection?

Epidemic viral respiratory infections have the obvious characteristics of group outbreaks, with many people becoming ill in a short period of time, or several people in a family becoming ill; while bacterial respiratory infections are more common in a sporadic manner, with few or no other patients with influenza or fever around the patients. If it is easily transmitted in groups, it is most likely a virus. Bacteria rarely do this. Because the virus can be spread through saliva splashes and other means.

In viral upper respiratory tract infections, nasal runny nose symptoms are generally more obvious than pharyngeal symptoms; while in bacterial upper respiratory tract infections, redness, swelling and pain in the tonsils or pharynx are more obvious. If accompanied by diarrhea or conjunctival congestion, it tends to be a viral infection.

3. What are the symptoms of bacterial infection?

Simple viral respiratory tract infections usually do not have purulent secretions, while purulent sputum is an important evidence of bacterial infection. Why is this so? This is closely related to the cause of the formation of purulent sputum.

Toxic infections have an acute onset, and systemic poisoning symptoms can be mild or severe; whereas bacterial infections have an acute or slow onset, and systemic poisoning symptoms are relatively severe. If the fever is not high at first, but becomes worse after 2-3 days, it is mostly a bacterial infection. Viral infections are more acute and the symptoms are unstable, while bacterial infections start out mild and then become severe. This is also related to the mechanism and size of viruses and bacteria.

Methods for determining the cause of bacterial or viral infections

Blood tests are used to determine whether a respiratory infection is caused by a virus or bacteria.

If this technology is developed, we will be able to get easier and more accurate diagnoses when we see a doctor in the future. Studies have found that three-quarters of patients with acute respiratory infections in the United States are treated with antibiotics, but the actual cause of their illness may be a viral infection. For most viruses, there is no targeted treatment.

When receiving antibiotic treatment, many beneficial bacteria in the human body will also be killed, so many people may experience some gastrointestinal problems. In addition, the overuse of antibiotics has also caused serious problems worldwide because of the emergence of drug-resistant bacteria, and the effectiveness of many drugs is becoming less and less.
