You get the option to use the cure on the boy or keep it for yourself. If you use it on the boy you keep a permanent -10 hp perk from the disease.
Can you avoid contracting the disease if you never get hit by any of the infected molerats by sneaking around or using followers for combat?
The Vault-Tec Assisted Targetting System first appeared in Fallout 3, and was both inspired and adapted from the combat mechanics of the original Fallout and Fallout 2. The original games were entirely turn based, which differs greatly from the current generation of first person shooter titles that Bethesda make. A main influence in including VATS was the ability to play Fallout 3 with out any skill in first person shooters, which hardcore fans may not necessarily have had. [citation needed]
Primarily, this gives you the benefit of a Turn-Based Strategy Approach. However, there are many other benefits to using VATS, both intentional and unintentional. These benefits include Critical Hits, Threat Detection, and the aesthetic Cinematic Combat. There are also V.A.T.S. Specific Perks that provide benefits when particular actions are performed in V.A.T.S., both to improve your combat ability, and include additional function.
The primary function of V.A.T.S. is to provide a turn-based approach to combat. In V.A.T.S., Fallout 4 drops into slow motion. During this time, you can choose specific body parts, on specific enemies. Each body part will display the percentage chance to hit, and when highlighted, will reflect the approximate damage you would cause on the enemies health bar.
This allows you to tactically plan out your attack. You can see your exact chances of landing a critical head shot. You can see how much damage your current weapon will land on the target, which gives you a good feel for enemy resistances to specific target areas, or from specific weapons. You should also keep in mind that guns tend to allow targeting specific parts of the enemy, where as melee and thrown weapons will only let you target the enemy.
This can be especially helpful at times where you wish to hit a specific part on the enemy for strategical reason. For example, a good shot to a ghouls leg will blow it straight off. The ghoul might still be at half health, but with the leg gone, the fight becomes a lot easier. As another example, you can target a grenade or explosive, either on an enemies belt or as it is being thrown. This can make for an easy way to dispatch of a group of enemies.
You can perform the same shots in real time, V.A.T.S. just makes it easier. You will also receive a 90% damage resistance, as with previous games. The damage reduction can be hard to make use of, due to the game moving in slow motion, but a quick hand can open V.A.T.S. as your player character is about to take a nasty hit, allowing a fair amount of the damage to absorb into V.A.T.S.
Keep in mind that to rely on V.A.T.S. constantly, you want to favor your agility stat and AP maximization. The higher your agility, the higher the weapon hit chances, and the more AP you have, the more shots you can fire off. AP is more directly impacted by a variety of things, including your weight, and your equipped weapon. There are a few consumables you can take to both replenish and temporarily increase it, and the actions of both running and melee attacking drains it regardless of if you are in V.A.T.S.
V.A.T.S not only lets you slow down time to fight the enemy in a strategic sense, but it also gives you the great benefit of critical hits.
Whenever you hit an enemy in V.A.T.S, your critical hit metre fills up. When your critical metre is full, you can hit the reload button to execute an automatic critical, in V.A.T.S. This guarantees a critical hit, which can be used to strategically blow a limb off a difficult enemy, or perform a high damage head shot at a distance normally difficult without luck and skill.
This ability is directly influenced by Luck. Luck not only determines how quickly you fill the metre, but you can unlock a perk that allows you to "bank" your critical hits. This allows you to execute several critical shots in one go, where normally you can only hold a single critical shot at a time.
This tactic comes from previous Fallout titles, and may reduce the experience of the game as it was intended.
V.A.T.S is designed to allow you to assess the enemy, and attack accordingly. As a result, V.A.T.S will detect targets that you normally would not see.
When you are in a dangerous area, you can attempt to enter V.A.T.S to locate potential threats. Enemies that are visible, but far in the distance or partially obscured by cover, will be highlighted. So will land mines. As a result, you can be more aware of the enemy presence, and reduce the risk of being accidentally blown up by land mines. In actual fact, this is a very important feature, if you find yourself easily blown up by unnoticed mines.
This is also a useful tactic, when approaching settlements or wandering NPCs, to determine whether they are aggressive or not. Traditionally, a friendly target will be displayed in a green outline, where a hostile target will be outlined in red.
Providing a great sense of cinematic immersion, actions carried out in V.A.T.S. will be acted out in slow motion. Furthermore, the camera will move to different angles, to give you a better view. It will zoom in on critical hits, and will even follow the enemy, at times. In some situations, this can help you determine the actions of enemies, where they might normally be too far away to tell.
There are several perks in the game that either add function to V.A.T.S., or provide increased ability in its use. Please note that accumulative benefits only count for the shots performed within the same sequence. To ensure I noted everything, I have used the Fallout 4 Wikia, for its page on Fallout 4 perks.
Ricochet
Killshot (Companion Perk, Robert MacCready): Increases the accuracy ,when targeting enemy heads in V.A.T.S., by 20%.
Based on playing the game one and a half times, it appears that the only player stat that automatically increases when you level is your health. I've certainly not observed any of the other stats you listed increasing due to level.
If someone runs across something else, please drop a comment.

You will contract the disease if:
Long story short, don't use a companion (or have them stay by the entrance), don't activate the protectron and Don't Get Hit. I was able to get through without catching the disease by abusing VATS and quick saves.
Note that the mole rats can be hit by grenades even while underground. If you get ambushed and have to reload, toss a Molotov Cocktail at the ground where the Mole Rat would appear and roast it early.
Also note that burrowed mole rats Will trigger mines. I tried to use mines on top of where they would spawn and blew myself up.
