Strain B started with a genetic mutation in patient zero that caused them to turn into a zombie. This strain differs from A in that all zombies can infect new people. Zombies infected with strain B can infect 1 person every minute.

This rapid transmission rate of 1 person per minute for zombies infected with strain B makes it highly contagious and poses a significant threat to population health. The infection potential increases exponentially as more and more people get turned into zombies.

As a result, strain B has the potential to cause a fast-spreading zombie apocalypse if not controlled immediately. The time it takes for strain B to infect a large population would be considerably shorter than strain A, which typically has a slower infection rate and limited transmission mechanisms.

With each infected individual turning into a zombie and being capable of infecting a new person every minute, the number of zombies would rapidly multiply. This exponential growth of the infected population would quickly overwhelm human populations and deplete resources.

Efforts to contain and combat strain B would require rapid response measures, including quarantine procedures, effective communication, and the development of potential vaccines or treatments. It would be crucial to identify and isolate infected individuals as quickly as possible to prevent the spread of the virus beyond manageable levels.

Overall, strain B, with its ability to rapidly infect new people, would present a highly dangerous and challenging situation. Responding to and containing such an outbreak would require immediate and coordinated efforts from medical professionals, governmental agencies, and the general public.
