The beginning of the end - zombie apocalypse

After that, you went about your business, and after a long day of work, you were about to go home. But what the news was saying was true: there was a screening campaign. So you went, and upon entering, they checked your arms and legs, your eyes, and a scanner. It beeped, indicating a negative result, so you left. But as you were leaving the tent, one of your companions tried to escape, but a soldier shot and killed him. Then you returned home, and a week passed since that event. The news continued to worsen; the reports of the first five days were fewer, and then one afternoon they stopped broadcasting altogether. You didn't hear any police or military cars, so you broke quarantine and went out. As you were walking through a park, it was almost night because you were alone, but you felt that something was wrong. You saw a person, and when you spoke to them, they turned around and looked at you. You were frightened because their eyes were bloodshot and yellow, and they were growling. But the zombie started running towards you. What will you do?
