'''World 1''' is a grassy-themed world in ''[[Dr. Mario World]]'' which serves as a tutorial for the game. Prior to playing a stage, [[Toad|Dr. Toad]] guides the player through a tutorial stage. The first area, or the first 20 stages give the player infinite hearts. Players start out with [[Dr. Mario]], where players can obtain [[Princess Peach|Dr. Peach]] or [[Bowser|Dr. Bowser]] by stage 3. Players earn their first assistant, the [[Goomba]], after beating Stage 5, as well as unlocking versus mode, staffing and the ability to add friends. Since version 2.0.0, skill summit is also unlocked and [[Toad|Dr. Toad]] is obtained as an extra doctor.

When areas are cleared, [[Toad (species)|Toads]] of different colors appear, including purple, yellow, blue, green, and red. In the second area, [[Dorrie]] also appears after clearing it. The [[virus]]es featured in the regular stages are red, blue and yellow.

|Stage 1
|align=left|Starting with 20 [[capsule]]s, the objective of this stage is to eliminate all viruses (17). 

In this stage, there are three colors of viruses in groups.

Prior to version 1.3.5, this stage only has red viruses, and [[Empty Block]]s exist. Additionally, the layout since that version had changed in version 1.4.0, and taken from version 1.4.0 of Stage 2 for version 2.0.0.

|Stage 2
|align=left|Starting with 25 capsules, the objective of this stage is to eliminate all viruses (25). 

This stage has gaps within the columns of red and blue viruses, along with yellow viruses in groups.

In the initial version of this stage, it only has red and blue viruses. Newer version of this stage has all three colors of viruses. In version 2.0.0, this stage's layout is moved to stage 1 while this stage has a new layout.
|-
|[[File:DrMarioWorld-Stage3-2.1.0.jpg|150px]]
|Stage 3
|align=left|Starting with 25 capsules, the objective of this stage is to eliminate all viruses (24). The only colors available in this stage are red and blue. 

This stage introduces [[Brick Block]]s, which are interspersed among the red viruses. Blue viruses are placed on the two leftmost and two rightmost columns. Since version 2.0.0, when players complete this stage, they can choose to be either Dr. Mario, Dr. Peach, or Dr. Bowser, rendering the other two unavailable after they have made their choice.

In the initial version of this stage, this was the first stage to have three colors of viruses (red, blue and yellow) along with empty blocks. In version 2.0.0, this stage's layout from a later version of this stage is moved to stage 2 while this stage is using a new layout. Prior to version 2.1.0, this stage layout was different, where three viruses of different colors were present.

|Stage 4
|align=left|Starting with 25 capsules, the objective of this stage is to eliminate all viruses (16). 

This stage introduces [[skill charger]]s, energy bottles that grant doctors a substantially-charged skill meter when activated.

In the initial version of this stage, there is a long column and row of yellow viruses, with the two other colors of virus to the left and right of the stage. A later version of this stage is the first stage to introduce skill chargers along with brick blocks, but since version 1.4.0, the stage layout changed in a way that brick blocks are not present.
|-

Additionally, players are introduced to the rainbow capsule, which will appear as the capsule after the next one after making seven clears, as indicated by the rainbow meter at the sides of the stage. Since version 2.0.0, players are able to select different characters, play the versus mode and add friends, as well as obtain their first assistant, a [[Goomba]].

In the initial version of this stage, this is the first stage to introduce [[Brick Block]]s, blocks that are eliminated when an adjacent feature, such as viruses or pills, are destroyed. The current version of this stage's layout used the stage layout of stage 9 prior to version 1.4.0, but with the capsule amount reduced from 30 to 25.
|-
|[[File:DrMarioWorld-Stage6-1.4.0.png|150px]]
|Stage 6
|align=left|Starting with 25 capsules, the objective of this stage is to eliminate all viruses (19).

The former three items are given a freebie each. By clearing this stage, this area of the world map gets cleared from viruses. This stage has viruses interspersed with two shells and an exploder.

After beating stage 10, the first half of Area 1 will be cleared of viruses, leaving the other half uncleared. Moreover, additional data will be downloaded where it must finish downloading before the player can proceed with the rest of the stages. Prior to version 2.0.0, when players complete this stage, they can choose to be either Dr. Mario, Dr. Peach, or Dr. Bowser. 

In the initial version of this stage, viruses are arranged in rows, with brick blocks and empty blocks in the rows between the rows with viruses. A later version of this stage is shaped like a "10".
