More than 90% of such cold, cough and fever are secondary to viral infections. Contrary to what many people think antibiotics are actually not needed to cure them. Just take cold medicines containing cetirizine and pseudoephidrine etc plus paracetamol 3 times a day. If cough starts then cough syrup. Main thing would be to maintain adequate hydration i.e. around 4-5 lt fluids per day and take adequate rest. You may get repeated fever spiked for upto 3 days but it will reduce later. Also steam inhalation and salt water gargles will help.
