Cold is a common systemic disease, mostly caused by viral infections. After a cold, some systemic symptoms may occur, such as fever, fatigue, joint and muscle pains, and some respiratory symptoms. Some patients may have more eye stools after a cold, and the first consideration is the local acute inflammatory reaction caused by the cold, which may manifest as khat symptoms. Especially in infants and toddlers, it is important to be alert to the fact that children’s body resistance is weak, and after a cold, especially a viral infection, can cause a local eye infection, resulting in viral conjunctivitis, which can manifest as red eyes and increased secretions, which is often seen as more eye stools. If there is a yellow, purulent discharge from the eye, this may be combined with some bacterial infection, and some eye drops, such as acyclovir drops, should be used promptly. If necessary, you can use tobramycin drops for eye drops, and pay attention to actively treat colds to prevent cross-infection.
