Hello, Welcome to HealthcareMagic forum. The symptoms mentioned by you can most probably be due to viral infection or a gram positive bacterial infection( like pharyngoconjunctival fever. The treatment for viral infections is mostly supportive while a bacterial infection needs a course of antibiotics . The confirmation of diagnosis requires a thorough evaluation and investigation by a pediatrician and treatment can be started accordingly with antipyretics analgesics and antibiotics . The eye drops seem appropriate and the red spot can be due to an engorged or inflamed blood vessel. As of now you should try the following . 1. Give the child plenty of fluids ( water ,soups etc) 2. Rest for the eyes , frequent cleaning with water and eye drops as prescribed , avoid scratching , rubbing. 3. The fever can be controlled with prescription drugs like acetaminophen or ibuprofen . 4. The cough is mostly due to congestion and irritation and might be better with saline gargles , steam inhalations thrice daily and decongestant cough syrups with chlorpheniramine ambroxol etc. Hope this answer is helpful for you. Wishing your child a speedy recovery. Regards
