On the high-speed train back to Shenzhen yesterday, I suddenly had a sore throat + cough + chills, feeling like I caught the flu. So I directly ordered a Marbofloxacin, and now I only have a slight cough and dizziness left. The effect is particularly amazing; it must be taken immediately when problems arise, because this medicine blocks viral replication. The side effects should be slow metabolism, and it may increase resistance, but to avoid infecting the child, I decisively took it.
