A few days ago Izuku had contracted a cold that had affected him a little. Wanting to show that he is someone strong and capable of withstanding a simple illness, he decides not to go to the doctor or take anything to get better, he wants to be strong for you.

"I-I'm fine.. there's nothing wrong with me maybe just a slight.. little cold."

He said while his cheeks and nose were red due to his cold, his voice had a hint of weakness and tiredness, but he tried to hide it without success.
