Conjunctivitis is a common eye disease. Once conjunctivitis occurs, it usually requires timely treatment, otherwise it is easy to infect others. However, due to different types of conjunctivitis, there are differences in treatment methods selected. For example, the two most common types of conjunctivitis are bacterial conjunctivitis and viral conjunctivitis. Today, let's understand the differences between bacterial conjunctivitis and viral conjunctivitis.1. Different pathogens:The main difference is the different pathogens. As the name suggests, the pathogen of viral conjunctivitis is a virus, while the pathogen of bacterial conjunctivitis is a bacterium. Bacteria and viruses are two different concepts. Viruses cannot survive for a long time after leaving the host, so they are easier to treat. Bacteria can survive for a long time even if they leave the human body. If these two diseases are not properly treated, they are prone to cross-infection, and the treatment is relatively difficult.2. Different symptoms:Viral conjunctivitis has less secretions and the texture is relatively thin. Bacterial conjunctivitis has a large amount of secretions, which are yellow and viscous liquid. Many patients will be stuck to their eyelashes by these secretions when they wake up in the morning, making it impossible to open their eyes normally.3. Different complications:Bacterial conjunctivitis often only causes harm to the conjunctiva of patients, and the impact is relatively simple. Viral conjunctivitis can cause fever, lymphadenitis, and even induce colds in patients. These two diseases need to be treated together with complications, otherwise they may induce each other in the later stage.
