Consider the following statements regarding African swine fever.

1. ASF is a highly contagious and fatal animal disease that infects domestic and wild pigs, typically resulting in an acute form of hemorrhagic fever.

3. There is no approved vaccine, which is also a reason why animals are culled to prevent the spread of infection.

Which of the statements given above is/are correct?
