Fortunately, few monkeys can afford airfare. It won't go pandemic, I don't think. But something else will.

Think about how the world would deal with something like airborne HIV.

Ebola kills too many too fast. The hosts die before they can travel, most of the time. And it happens in a part of the world where most people use "their feet for their only carriage", as Bob Marley said. Ebola would have already gone pandemic if it was going that way.

Maybe if it mutates to something even worse at some point.

The worst part I see is that survivors can still shed virus. Eventually, that might mean that pockets of Ebola will be treated by genocide.

A 48-year-old man from Wisconsin recently contracted a rare blood infection that led to the amputation of his legs and parts of his arms, according to news reports. And the most likely source of the devastating infection was his own dog.

Greg Manteufel went to the hospital with what he thought was the flu, local news outletFox 6 Nowreported yesterday (July 30). But within a week, the doctors had to amputate both of his legs and, later, portions of his hands and forearms. The amputations were necessary after the infection caused Manteufel's blood pressure to drop drastically, which severely reduced blood flow to his limbs and led to tissue death.

Blood tests revealed that Manteufel's infection was caused by abacterium calledCapnocytophaga, according to Fox 6 Now. [11 Ways Your Beloved Pet May Make You Sick]

These bacteria are found in the mouths of cats and dogs, according to the Centers for Disease Control and Prevention(CDC). Up to 74 percent of dogs and 57 percent of cats have Capnocytophaga, but the bacteria don't cause illness in dogs and cats, the CDC says.

In humans, however, it's a different story. In very rare cases, the bacteria can spread to humans through bites, scratches or close contact with cats and dogs. The people most at risk for this infection are those with weakened immune systems, according to the CDC. (It's unclear if Manteufel had a weakened immune system).

If a person becomes infected withCapnocytophaga, the bacteria can spread to the bloodstream and cause infections in various parts of the body, including ablood infectionknown as sepsis. Sepsis occurs when the immune system responds overwhelmingly to an infection, triggering body-wide inflammation and, potentially, organ failure.

Most people who get sick with the bacteria typically start experiencing symptoms within three to five days of becoming infected, but symptoms may occur anywhere from one to 14 days after infection, according to the CDC. Symptoms include blisters, redness, swelling, pus or pain around the animal bite location (if a bite was involved), fever, diarrhea, headache, vomiting and muscle or joint pain.

As in Manteufel's case, the infection can sometimes lead to gangrene, ortissue death, and require amputations to save the rest of the body.

Dr. Silvia Munoz-Price, an infectious-disease specialist with Froedtert & the Medical College of Wisconsin told Fox 6 Now that the case is extremely rare. "More than 99 percent of the people that have dogs will never have this issue. It's just chance," she said.

I've heard anecdotal accounts from respectable colleagues that point to weird occasional dental disease situations that seem to only happen to cat fanciers.  There is enough there to make me believe stuff like that does happen.

I have dogs and a cat, and my own dog is attracted to, and wants to lick, any tiny scratch or scab that has the tiniest bit of bleeding. I am at risk, I'm sure.

🦠 Typhus reaches 'epidemic levels' in parts of Los Angeles area

Typhus reaches 'epidemic levels' in parts of Los Angeles area
by Dennis Romero and Andrew Blankstein / Oct.05.2018 / 4:25 PM AKDT

LOS ANGELES — Health officials on Friday reported a typhus outbreak in Los Angeles County and say it has reached "epidemic levels" in the city of Pasadena.

Twenty cases have been reported in Pasadena, most in the last two months, health officials told NBC News, noting that a normal year would typically only see five infections. The city of Long Beach, California, has 12 cases so far in 2018 — double the normal annual number, said Emily Holman, the city's infectious disease response coordinator.

The number of cases in the rest of the county since July is nine, which counts as an "outbreak," Los Angeles County Department of Public Health officials said in a statement. Pasadena and Long Beach have their own health departments even though they exist within the county.

“The Pasadena Public Health Department is reporting epidemic levels of typhus fever this year," read a statement from that city on Friday.

The official source of the outbreak is said to be fleas from domestic and wild animals.

"Infection happens when the feces from infected fleas are rubbed into cuts or scrapes in the skin or rubbed into the eyes," the county health department states on its website.

Some experts, however, say the true culprit is the inhumane conditions the county's expanding homeless population lives in.

"All of the cases have a history of living or working in the downtown Los Angeles area," a county health spokeswoman said via email.

Andy Bales, the CEO of the Union Rescue Mission, which has nearly 1,400 beds for those fleeing or avoiding downtown's Dickensian streets, said, "The conditions on Skid Row are ripe for even more serious issues than this."

In 2014, Bales had a leg amputated after he was exposed to flesh-eating bacteria downtown.

The office of Mayor Eric Garcetti said it's on the case.

"We're deploying every available resource to help control and stop this outbreak," mayoral spokesman Alex Comisar said via email. "The City and County have formed a dedicated task force through our Unified Homelessness Response Center to keep Angelenos safe, and ensure everyone gets the treatment they need as quickly as possible."

Typhus or typhus fever is a flea-borne infectious disease that can cause high fever, headache, chills, and body aches, rashes and in rare cases, meningitis and death.

Health officials in Pasadena are blaming the outbreak on a warm summer and fall and human interaction with animals in neighborhoods that have an "interface" with wildlife in canyons and the Angeles National Forest. They say the disease has nothing to do with homelessness in their high-income city.

The Los Angeles County Department of Public Health spokeswoman said via email that officials are investigating the source of the typhus in downtown L.A. by searching specifically for "high concentrations of infected fleas and/or infected rats, feral cats and opossums."

Bales noted, "There are lots of rats on Skid Row, and there are lots of dogs that belong to homeless people."

In September the nonprofit research organization Economic Roundtable released an analysis that concluded the county has 102,955 homeless people — nearly double what government officials had previously reported.

"The numbers on the sidewalk have increased dramatically," said Alice Callaghan, founder of the Skid Row services organization Las Familias del Pueblo. "They're like refugee camps."

Asian ticks have arrived in the United States, and they’ve brought disease with them
Mike Wehner @MikeWehner
November 29th, 2018 at 6:43 PM


Outdoor adventurers in the United States have plenty of tick problems of their own, and anyone who ventures into the woods in many areas of the country needs to be on the lookout for the tiny parasites and make sure none have latched on. Now, a new invasive tick species is getting a foothold in the country, posing a danger to humans and animals.

The ticks are a nuisance in their native Asia where they have been blamed for spreading disease to humans as well as affecting livestock. As the Washington Post reports, the ticks are capable of carrying many diseases and drink enough blood to affect the output of dairy cattle production by up to 25 percent.

A new report by the CDC highlights the dangers posed by the ticks. According to the organization, the tick species has been spotted in the United States in 2017 and 2018, located in a number of states including Arkansas Connecticut, Maryland, New Jersey, New York, North Carolina, Pennsylvania, Virginia and West Virginia.

The species, called the Asian longhorned tick (Haemaphysalis longicornis), has a knack for spreading. Females of the species can lay eggs without mating, making it fairly easy for the parasites to bolster their numbers in short order.

“The presence of H. longicornis in the United States represents a new and emerging disease threat,” the CDC says. “Characterization of the tick’s biology and ecology are needed, and surveillance efforts should include testing for potential indigenous and exotic pathogens.”

If you believe you’ve found one of these ticks there’s a few things you should do, according to the CDC. For starters, if you find it on your body or pet or animal, remove it immediately. Then place the tick in a jar or vial of rubbing alcohol and seal it. Contact your state’s agriculture department for information on tick identification and, if necessary, follow up with your veterinarian (if the tick was found on a pet).

Second-largest Ebola outbreak in history spreads to major Congo city

Ebola’s spread from Congo growing as WHO calls risk ‘very high'

DAKAR, Senegal — The second-largest Ebola outbreak in history has spread to a major city in eastern Congo, as health experts worry whether the stock of an experimental vaccine will stand up to the demands of an epidemic with no end in sight.

Butembo, with more than 1 million residents, is now reporting cases of the deadly hemorrhagic fever. That complicates Ebola containment work already challenged by rebel attacks elsewhere that have made tracking the virus almost impossible in some isolated villages.

“We are very concerned by the epidemiological situation in the Butembo area,” said John Johnson, project coordinator with Medecins Sans Frontieres in the city. New cases are increasing quickly in the eastern suburbs and outlying, isolated districts, the medical charity said.

The outbreak declared on Aug. 1 is now second only to the devastating West Africa outbreak that killed more than 11,300 people a few years ago. There are currently 471 Ebola cases, of which 423 are confirmed, including 225 confirmed deaths, Congo’s health ministry said late Thursday.

Without the teams that have vaccinated more than 41,000 people so far, this outbreak could have already seen more than 10,000 Ebola cases, the health ministry said .

This is by far the largest deployment of the promising but still experimental Ebola vaccine, which is owned by Merck. The company keeps a stockpile of 300,000 doses, and preparing them takes months.

“We are extremely concerned about the size of the vaccine stockpile,” WHO’s emergencies director, Dr. Peter Salama, told the STAT media outlet in an interview this week, saying 300,000 doses is not sufficient as urban Ebola outbreaks become more common.

Health workers, contacts of Ebola victims and their contacts have received the vaccine in a “ring vaccination” approach, but in some cases all residents of hard-to-reach communities have been offered it. The prospect of a mass vaccination in a major city like Butembo has raised concerns. Salama called the approach “extremely impractical.”

A WHO spokesman said shipments of doses arrive almost every week to ensure a sufficient supply for the ring vaccination. “No interruptions of vaccine supply have occurred to date,” Tarik Jasarevic said in an email to The Associated Press. “Merck is actively working to ensure sufficient number of doses continue to be available to meet the potential demand.”

This Ebola outbreak is like no other, with deadly attacks by rebel groups forcing containment work to pause for days at a time. Some wary locals have resisted vaccinations or safe burials of Ebola victims as health workers battle misinformation in a region that has never encountered the virus before.

A “fringe population” has regularly destroyed medical equipment and attacked workers, Health Minister Dr. Oly Ilunga Kalenga told reporters on Wednesday.

The Ebola virus is spread via bodily fluids of those infected, including the dead.

The outbreak “remains serious and unpredictable,” the World Health Organization said in an assessment released Wednesday. Nine health zones have reported new cases in the last week, and some have been unrelated to known victims, meaning that gaps in tracking remain in a region with a dense, highly mobile population.

Thousands of people have been organized by Red Cross societies and others to go house-to-house dispelling rumors and checking on possible contacts of victims.

Dr. Fatoumata Nafo-Traore, Africa regional director for the International Federation of Red Cross and Red Crescent Societies, joined one awareness campaign in the outbreak’s epicenter, Beni, this week.

The head of one family thanked her for the face-to-face contact, saying he didn’t even have a radio and didn’t understand what was happening. “Ignorance is the enemy,” another resident said.

Given the years of conflict in eastern Congo, it’s essential that households trust why the health workers are there, Nafo-Traore told the AP.

While she called the insecurity “very worrying,” she said that with new tools at hand, including vaccines, “there is great hope.”
