Everyone sympathizes with abused and impoverished people. But individuals who use their troubles to justify asylum in the U.S. is ridiculous. Most who flee, choose the U.S. because it offers the longest and most sumptuous list of entitlements. Aliens granted asylum become wards of the U.S. taxpayer at a colossal cost. Most American citizens find illegal migration abhorrent because it accomplishes nothing for either nation.
If the pandemic is real, these people need to "shelter in place" and practice "social distancing" like the rest of the world. They have no special immunity and if already infected, leave a trail of sickness through several nations. They're also dangerous in other ways because many are criminals. Their primary problem isn't different from ours except in magnitude. The primary problem of course is the government. It rarely helps except in time of war.
They need to have their revolutions and adopt the U.S. system, a constitutional republic. If they don't like that system, they need to find another nation within which to seek asylum. No other system ensures the freedoms and prosperity provided by nations with intelligent constitutions and law enforcement to protect peaceable, lawful citizens from their government. They should create it for themselves instead of running away.
Funding anything beyond deportation is not a responsibility of taxpayers. Medical care is expensive and an individual responsibility unless the home nation provides it. Regarding creature comforts while under arrest, most citizens would rescue dogs before illegal aliens. The message is clear. Find another nation willing to provide free food, shelter, medical care, education, transportation, cell phones and money for creature comforts.
