Being a magical disease, the L-Virus (now the LAR Virus), had 100% communicability. Thus any girl Maria had come into contact with (within a few feet) had been infected last night. Having gone to a crowded nightclub, the virus was now spreading across the city rapidly.
Meanwhile, the original L-Virus had been spread by Shannon and Gina across a shopping mall. While this version was not as extreme in it's effect, as the original version, it too, was prone to mutation. By morning, the third variant of the virus had appeared, what would later be known as the "Cutie Strain". While it didn't reverse the aging process, nor did it's victims exude emotion-controlling pheromones, this version of the virus did cause physical changes- those affected became more attractive and girlish in appearance, typically losing about 6" of height, and becoming more slender. Gina was likely the source of this version.
The vast majority of the victims didn't report their condition, either not noticing or not caring. Thus for some time, the LAR version was considered to be the true epidemic, and even then, not all it's victims suffered from extreme regression. Most only had their age reduced by 10-20% or so. A 20 year old becoming 16 again was noteworthy, but could be missed. As would a 30 year old becoming 24 again.
Less common were those girls who lost about 30-40% of their years; such a regression couldn't be ignored. And finally, there were those who lost 50-70% of their age; Maria herself, who went from 39 to 13 and change (being reduced to 35% of her original age), and poor Rachel, who went from 25 to about 7 and a half.
The speed of the regression varied; while the bulk of Maria's regression had taken place over the course of a couple of hours, it didn't fully halt for a few hours after that. Doctors around the world were completely baffled- for a human being to lose so much mass raised a lot of questions. Where did the missing mass go? How did the victim's body manage to restore itself to a younger state?
The change in the victim's sexuality, as it wasn't life threatening, along with the hypersexuality went without comment for the first few months, but once it was realized that the effected no longer had any desire for men, there was a panic.
Jack watched all of this with some amusement, though he realized that the new world he had envisioned would present some problems- while it was fun watching pretty girls kiss and make out with each other all the time, pretty soon, no girl would want to have sex with him. Not to mention the fact that so many girls were basically underaged lolis- cute to look at, but even he felt a little dirty perving on them.
Something needed to be done. He could cure the virus, of course, the ring gave him such power. But that was boring! He'd long been curious about what it would like to become a woman himself, so he decided to create a new virus. One that would turn men into sexy babes!
But first, he created another virus, one that would go unnoticed at first. The affected women would gain the ability to impregnate other women by passing on genetic information through an enzyme in their saliva. If this enzyme entered the blood stream, say by a bite, it would eventually cause a woman's egg to become fertilized, resulting in a child that had the DNA of both women.
Then he created his Sexy Virus. Rather than turning the victims into lolis or petite girls, this virus, which only affected men, rewrote their DNA and caused their bodies to change gender. They would retain their original height, and gain wide hips and large breasts, becoming sexy bombshells. Hypersexuality, of course. Some age regression, but rather than simple math, he calculated a formula to where, the older you were, the more you would regress, while younger victims would be barely affected at all.
Now, to find his Patient Zero. He could have changed himself first, but he didn't want to draw attention to himself.
