When in university, my brother gave me a 'protest button' with:
             New Mexico
       Land of the flea
     Home of the plague


From the New Mexico Dept. of Health:
Quote
Plague is an infectious disease of animals and humans caused by a bacterium named Yersinia pestis. People usually get plague from the bite of a rodent flea that is carrying plague bacteria or by handling an infected animal.

Although plague is a rare disease, about half of US cases each year occur in New Mexico. Antibiotics are effective against plague, but if an infected person is not treated promptly the disease can be life-threatening.

...

There has been one Human Plague Case in New Mexico in 2019 ...
There have been no human plague cases in 2018.
There were four Human Plague Case in New Mexico in 2017 ...
There were four Human Plague Cases in New Mexico in 2016 ... All survived the illness.

DR Congo Measles: Nearly 5,000 Dead In Major Outbreak
https://www.bbc.co.uk/news/world-africa-50506743

Measles has killed nearly 5,000 people in the Democratic Republic of Congo in 2019, authorities said, after the disease spread to all the provinces in the country. Close to a quarter of a million people have been infected this year alone.

The World Health Organization (WHO) says this is the world's largest and fastest-moving epidemic.

Four million children have been vaccinated, but experts warn that this amounts to less than half of the total in the country - and not enough vaccines are available. The majority of those infected with measles in the country are infants.

Measles in DR Congo has now killed more than twice the number who have died of Ebola there in the last 15 months.

It is estimated that a global total of 110,000 people die from measles each year.

Border Patrol Denies Undocumented Immigrants Free Influenza Vaccine
https://abcnews.go.com/amp/Health/border-patrol-denies-undocumented-immigrants-free-influenza-vaccine/story?id=67237256

Peak flu season is fast approaching North America and the U.S. government is actively encouraging anyone over 6 months old to vaccinate – that is, unless you are one of the thousands of people being detained in Customs and Border Protection facilities for undocumented entry

“To us in the medical community the situation is alarming. When the CBP stated in August that they weren’t planning on vaccinating we saw this as egregious to deny basic health care access to people forced to stay in their care," said Dr. Bonnie Arzuaga, a Boston-based pediatrician and one of the founders of Doctors for Camp Closure.

The organization is a volunteer group of 2,000 U.S. based physicians who support the closing of the Customs and Border camps because of public health concerns. The organization volunteered to provide free influenza vaccines to those detained but the government never responded.

“We got no response, not even an acknowledgement of the letter," said Arzuaga.

Polio eradication program faces hard choices as endgame strategy fails

The “endgame” in the decadeslong campaign to eradicate polio suffered major setbacks in 2019. While the effort lost ground in Afghanistan and Pakistan, which recorded 116 cases of wild polio—four times the number in 2018—an especially alarming situation developed in Africa. In 12 countries, 196 children were paralyzed not by the wild virus, but by a strain derived from a live vaccine that has regained its virulence and ability to spread. Fighting these flare-ups will mean difficult decisions in the coming year.

The culprit in Africa is vaccine-derived polio virus type 2, and the fear is that it will jump continents and reseed outbreaks across the globe. A brand new vaccine is now being rushed through development to quash type 2 outbreaks. Mass production has already begun, even though the vaccine is still in clinical trials; it could be rolled out for emergency use as early as mid-2020. At the same time, the Global Polio Eradication Initiative (GPEI) is debating whether to combat the resurgent virus by re-enlisting a triple-whammy vaccine pulled from global use in 2016. That would be a controversial move, setting back the initiative several years, as well as a potential public relations disaster—an admission that the carefully crafted endgame strategy has failed.

...

The heart of the problem is the live oral polio vaccine (OPV), the workhorse of the eradication program—the only polio vaccine powerful enough to stop viral circulation. Given as two drops into a child’s mouth, OPV for decades contained a mix of three weakened polio viruses, one for each of the three wild serotypes that have long plagued humanity. All three serotypes in the vaccine have the potential to revert to more dangerous versions; that’s why the endgame strategy calls for deploying OPV in massive campaigns to eradicate the wild virus, then ending its use entirely.

Wild serotype 2 was last sighted in 1999, so in 2016, as a first step in the endgame, all 155 countries using OPV replaced the trivalent version with a bivalent one, lacking the type 2 component. Announced with great fanfare, “the switch” was billed as the biggest vaccine rollout ever. Some type 2 outbreaks would inevitably occur for several years, GPEI realized, but those would be fought, somewhat paradoxically, by rushing in essentially the same vaccine that gave rise to them in the first place: a live, monovalent vaccine targeted against type 2 (mOPV2). If used in well-run campaigns, and only in outbreak regions, mOPV2 could stop outbreaks without seeding new ones, models suggested.

It often has not turned out that way. Instead of fading away, the number of type 2 outbreaks in Africa almost tripled from 2018 to 2019. Most of today’s outbreaks stem from mOPV2 responses to previous ones, and GPEI is burning through its emergency stockpile of mOPV2 faster than it can be replenished. (Based on a small study in Mozambique, a WHO advisory panel recently recommended halving the dose to one drop if supplies run critically low, despite what it calls “a relatively weak level of evidence” that the smaller dose is as effective.) Meanwhile, the risk of explosive outbreaks around the globe is ratcheting up, because millions of children born since the switch have little or no immunity to type 2 virus.

China Investigates SARS-like Virus as Dozens Struck by Pneumonia
https://dw.com/en/china-investigates-sars-like-virus-as-dozens-struck-by-pneumonia/a-51843861

Chinese health authorities on Tuesday said they are investigating 27 cases of viral pneumonia in central Hubei province, amid online speculation that it could be linked to the SARS flu-like virus that killed hundreds of people a decade ago.

Wuhan health officials issued an emergency notification on Monday after local hospitals treated a "successive series of patients with unexplained pneumonia."

Of the 27 reported cases, seven are in a critical condition and 18 are stable, the Wuhan Municipal Health Commission said on Tuesday on its Weibo social media account. ...

A 2003 outbreak of the highly-contagious SARS virus was covered up and killed hundreds of people.

China Confirms More Cases of Mystery Viral Pneumonia
https://medicalxpress.com/news/2020-01-china-cases-mystery-viral-pneumonia.html

China on Friday confirmed more cases of a mystery viral pneumonia that has sparked fears about a resurgence of SARS, the flu-like virus that killed hundreds of people more than a decade ago.

The 44 cases, up from the initial 27 announced Tuesday, include 11 "severe cases," health authorities in the central Chinese city of Wuhan said in a statement.

The authorities are still in the process of identifying the cause of the infection, but "influenza, avian influenza, adenovirus infection and other common respiratory diseases have been excluded," the Wuhan health commission said on Friday, without mentioning SARS, which is caused by a coronavirus.
