Saobavirus is a virus that created a pandemic in countries south of the continent of Baoji. The first infected person was a citizen of the city of Samihbal, in United Roblox of Indonesia,. The virus started on January 20, 2021, and on December 17, 2021, the vaccine was created and the cure was completely completed. The virus is highly contagious, as Robloxians are advised to call a medical service and stay away from any infected Robloxians immediately should they see an infected Robloxian.

Seven counties of United Roblox of Indonesia had to evacuate survivors due to the infected Robloxians developing a new phase of the virus, which made the infected person behave like a zombie from the movie "World War Z". The Roblox Health Organization placed the virus as "Priority Extreme". As soon as the cure was applied to the last infected person, samples of the virus were sent to Ro-Indi, where they were analyzed by scientists, and the vaccine was launched in Eurobloxia, Baoji and Bloxveld.

In 2029, a smaller outbreak of the dangerous version of the virus ravaged the Central North Dabloxa, but the outbreak was prevented from becoming a pandemic.
