[Alien Nation] what is the world like now, 30 years after the new comer arrival?

Have they spread out more through the country? The world?  Has recovered and studied newcomer tech become wide spread?
What might some the main characters be up to by this point?

The first people to notice the odd flaking disease were eventually identified to be those who had extensive relationships with the Newcomers, many of them sexual.  Scientists called it a "fungal analog", a benign growth that pervaded the circulatory ducts in the slave ship the Tenctonese arrived in.  

Unfortunately humans had no immunity to the spores, which took several months to germinate.  By the time the vector was identified, the disease had spread around the world, carried in the upper atmosphere by outventing of the *Gruza*.  

Symptoms invariably progressed from sloughing skin to open sores to necrotic rot within a year, unless extensive debridement of the wounds took place.  Victims would lose their fingers, eyes, ears, and nose first.  Death would eventually occur due to septic infections from the loss of protective skin cover.

The Newcomers were, sadly, unable to help to human race as it wasted away because they themselves were succumbing at alarming rates to native Earth infections.  Many previously undescribed bacteria, fungi, protists, and other disease-causing agents were able to make themselves at home in the Tenctonese biology.  The worst of them was known as 'corn canker' from its origin in maize crops and the way that it caused rows of blisters on Newcomer skin to burst out that looked like corn kernels.

Within a decade most of the human food crops had perished from another disease scientists likened to terran roundworms.  They originated in the sewage systems of the alien ship and ravenously ate their way through all plant life they encountered. 

Native ecosystems collapsed from the loss of the primary photosynthetic producers.  Wild animal populations disappeared with their food sources.  Many of the remaining humans starved.

Global climate patterns altered from the loss of vegetation as entire regions were impacted by changes in reflectivity, heat absorption, water retention, and erosion.  Civilization as we know it came to an end with the "lucky" survivors eking out a meager existence in an increasingly hostile world.

Fortunately for them, the alien species who the Newcomers had escaped from arrived on Earth, searching for their lost slaves.  They found a ripe new species to exploit - humans.  Easily rounding up the primitive tribal groups, the new aliens made a sport of it, holding royal "hunts" and awarding trophies to each other.  They eventually acquired enough new fodder to trade and breed and create an entire new class for their pleasure.

Thus did humanity survive.
