They figured the virus comes from the dead bodies because they haven't buried them. The number of the dead bodies was so huge and they start to bury the bodies. Then. The workers who are bury the bodies has been affect with the same virus because they did not get shot to avoid the disease. Researchers protested because they did not find a solution to the virus. They have done many test but no one without side effect. They have only the one option but the side effect maybe will be more dangerous. It is give them a shot but the shot may turn the workers to animals because the shot will change the genes in human body. The change will be in the chromosome 20 and that chromosome charge in human shape. If the human takes the shot immediately will change to monkeys and this is the biggest issue but the researchers have no other solution to replace the shot. They made a big meeting to see if they agree about that. The meeting ends with vote to give the workers the shot without tell them about the side effect. The workers took the shot and after two days while the do their jobs the change to monkeys and no one know what is happening. After three days, they have been unknown to their family and their friends.
