Presidential campaign in chaos as campaign manager passes away after a mysterious illness! Will this cause just a minor blip in polling numbers or is this a harbinger of something more ominous?
—Case Teaser

Patient Zero is a case featured in Criminal Case: Disease Control as the first case of the game. It is the first case to take place in Transmission stage.


The player was welcomed in the squad by Chief Alexis Farley, a world-class epidemiologist. Before the player could be introduced to the rest of the team, Chief Farley briefed the player and Deng that US presidential candidate Ernie Samuels had reported a weird disease in his campaign manager, Faizan Shakoor and thus the duo went to Faizan's house to investigate his illness. However, they found Faizan dead when they reached his place.

Natalina confirmed that the campaign manager indeed died due to a previously undiscovered virus that attacked the victim's cardiac muscles and mimicked the action of a heart attack. Natalina said the possibility of murder could not be ignored in this case, therefore the team would be treating the case as a murder investigation until disproved otherwise.

During the investigation, the team learned that the campaign staff booked an Indian restaurant for a party and Faizan ate chicken curry there which infected him. The team also learned that Faizan was engaged with George Curtis and had beefed with intern Charlotte Berry and Candidate Ernie Samuels himself on how to run the campaign. The team also discovered the victim intended to sue Indian Chef Ishram Panday for negligent and unclean cooking. After quarantining Faizan's brother Rehman Shakoor as he was in contact with the victim, the team incriminated Ishram Panday as the chef who cooked the infected curry.

Ishram said that he was hired as the chef who cooked on the campaign night celebration. He cooked up the chicken curry that infected Faizan, but claimed to have no idea of the curry being contaminated. Panday claimed that all of the campaign staff including the presidential candidate ate from the infected curry. However, Panday said the restaurant had not yet served anyone else after the campaign event. After handing the chef to the authorities, the duo reported to the chief who was horrified at the possibility of all the campaign staff including the presidential candidate getting infected.

Chief Farley introduced the player to their other partner, Abbas, with whom the player went to talk to Ernie Samuels and tell him to quarantine himself and his staff. Ernie was concerned how he could avoid the public when the Iowa Caucuses were in two days, so he asked the player to check if the technological equipment he had in his campaign office worked well enough to allow Ernie a chance to campaign digitally. After the team confirmed Ernie could campaign virtually, the duo looked who Faizan was in contact with recently to quarantine them. After finding Faizan's journal and looking at his schedule, they determined everyone had been quarantined except for an activist Rosie Allen who was based in San Francisco.

Meanwhile, the team's microbiologist Arjuna wanted to talk to the player. Arjuna told the player that the virus had an incubation period of two days in Faizan but took only one day from the onset of symptoms to his death, likely making the virus highly lethal. The microbiologist also determined that the symptoms were mainly chest pain and fever, with a high blood pressure. Arjuna wanted the player to look for the actual agent of transmission. After analyzing chicken from the restaurant, Arjuna determined that the chicken was the carrier of the virus. The player and Arjuna talked to Ishrwar where he got his chicken, to which the chef said it was delivered to him by GoodChick poultry farm.

The team reported their findings to the chief when the team's consultant, Andres, told the team he could find nothing on the poultry farm that Ishwar mentioned; it is as if the farm never existed. The chief found the findings concerning, but decided the important thing to do right now was to ensure the virus does not spread, and ordered the team to go to San Francisco to quarantine Rosie Allen.
