The Democratic Republic of Congo continues to fight off the worst Ebola outbreak in years. Butembo, a major regional hub of 1 million people, has now had a confirmed death.

The World Health Organization is worried, and recommends you worry too.

Via HuffPo:

The Democratic Republic of Congo has confirmed its first Ebola death in the eastern city of Butembo, a trade hub with Uganda that is home to almost a million people. This first urban death, combined with ongoing violence in the northeastern outbreak area in DRC and some community resistance, is worrying experts that the slowing outbreak could still escalate.

Having already killed 87 people, this outbreak is close to becoming the eighth-largest Ebola outbreak in history. While officials have been pleased with the decreasing pace of cases and a successful vaccination and contact tracing campaign, this new case in an urban setting is worrisome, Peter Salama, the World Health Organization’s emergency response chief, told HuffPost.

“When you have an Ebola case confirmed in a city with 1 million people, no one should be sleeping well tonight around the world,” Salama said.

The patient traveled from the current outbreak hotspot, the town of Beni, 35 miles southwest, to Butembo after disregarding medical advice, Salama said. The patient died at a health facility there.

While WHO team members are on site and working to quickly trace and vaccinate those with whom the patient came into contact, the potential for further spread could “change the trajectory of the outbreak,” Salama said.

Last year in Yemen, cholera ran rampant. In a single week, the United Nations reported 50,000 new cases of the diarrhea and vomit-inducing illness. In 2018, thanks to computer modeling, the number of individuals that have succumb to the virus have dropped to an average of 2,500 cases over a seven-day period.

From The BBC:

The Met Office [the UK government's meteorological authority,] produces a rainfall forecast for Yemen. Using its supercomputers, it is to determine the specific amount of rain that will fall and pinpoint the areas it will hit within a 10km (six-mile) radius.

These are important because downpours overwhelm the sewerage system and spread the infection.

The forecasts are used in conjunction with a computer model developed by Prof Rita Colwell, at the University of Maryland, and Dr Antar Jutla, at West Virginia University.

Once in the numbers pulled from the Met forecast and the computer model are available, the information is cross-referenced with factors such as the suspected outbvreak area's population density, what access to clean water there may be in the area (cholera is spread, rapidly by ingesting contaminated water,) and the seasonal temperature in the region as the virus LOVES it when it's warm... like, warm for Yemen warm.

According to The BBC, by referring to all of the available data, scientists have been able to accurately predict large scale cholera outbreaks up to four weeks in advance. This provides aid workers, hospitals and what health authorities are able to operate in the war-torn country to vaccinate locals in the target area. Read the rest

A few days after skipping out on the Democratic Republic of Congo, Ebola decided, ‘nah,’ cropping back up in a town of around 60,000 potential carriers called Mangina, located in Congo’s North Kivu province. Since the latest outbreak was identified, four people have died of the hemorrhagic fever. The World Health Organization is hoping that the strain of Ebola that’s shown up in North Kivu province is the same as the one that Congolese health workers and an international team of medical professionals were able to put down, this past July: they have a vaccine for that particular strain and it works fabulously. The WHO plans on giving the vaccine a go with this new outbreak—fingers crossed! Unfortunately, in addition to the possibility that the vaccine might not work for this Ebola outbreak, those tasked with stemming the spread of the disease are facing a threat that doesn’t involve contracting a virus: Working in an active war zone.

From The New York Times:

But North Kivu Province, the volatile region in the Democratic Republic of Congo where the new outbreak is centered, creates security complications that health officials did not confront in the outbreak they just defeated in northwest Équateur Province, 1,550 miles away. The World Health Organization is worried about the safety of medical workers in North Kivu and their access to areas controlled by militants.

“This new cluster is occurring in an environment which is very different from where we were operating in the northwest,” said Dr. Peter Salama, the deputy director general of the health agency and the head of its emergency response unit.

So… remember a few days ago when the World Health Organization declared the Ebola outbreak in the Democratic Republic of Congo as having come to an end. Well, the disease is back on its bullshit again with a brand-new outbreak in the same damn country.

From Al Jazeera:

Four cases of the virus were confirmed in northeastern North Kivu province, the DRC's health minister said in a statement on Wednesday, though there was no indication they were linked to the country's previous - and ninth - Ebola outbreak in northwestern Equateur Province.

"Although we did not expect to face a tenth epidemic so early, the detection of the virus is an indicator of the proper functioning of the surveillance system," Health Minister Oly Ilunga said.

However, it might be impossible to use a vaccine to tackle the new outbreak, Peter Salama, a senior World Health Organization (WHO) official, said.

Yeah, that’s right: the vaccine that worked a miracle this past go-around with Ebola may not be able to do anything for anyone during the latest outbreak of the disease. Experts currently believe that the iteration of Ebola that Congo is currently facing could be one of three strains Zaire, Sudan or Bundibugyo. If it’s the Zaire strain of the disease? Party time: the vaccine developed by Merck should work a treat on it. Unfortunately, if one of the other two possible strains is responsible for the latest outbreak, The WHO admits that there may not be a vaccine option for them to undertake. Read the rest

Last week, officials in charge of stemming the latest outbreak of Ebola virus in the Democratic Republic of Congo began the process of inoculating healthcare workers and other individuals who may have come in direct contact with infect individuals, in the Congolese city of Mbandaka. According to The Globe & Mail, inoculations are now also being doled out in Bikoro, a town in the northwest of Congo, where 5 of the 12 confirmed cases of Ebola are believed to have originated.

It’s believed that there are at least 56 cases of the Ebola: 35 cases have been confirmed, leaving 13 probable cases and 13 suspected cases for doctors to deal with and patients to fret over.

From The Globe & Mail:

Amid worries of the spread of Ebola, several schools in the Iboko health zone, about 180 kilometres (112 miles) southeast of Mbandaka, have been closed, according to reports by U.N.-backed Radio Okapi.

Many residents in one of the Iboko localities told Radio Okapi that they prefer to stay at home to avoid infection, following the death of a woman who had Ebola in the nearby Bobala area.

One resident said that what they first thought were rumours were becoming reality with the death and that they were very scared to interact. Four confirmed Ebola deaths have taken place in the Iboko health zone, according to Congo’s health ministry.

Given that the hemorrhagic fever-causing virus has up to a 90% chance of killing those that it infects, to say that such precautions and the fear that those living in areas where the virus has cropped up during this most recent outbreak are reasonable would be an understatement. Read the rest

Last week, the Democratic Republic of Congo’s latest Ebola outbreak was confirmed to have spread to Mbandaka, a transportation hub, home to over one million people. As of the time that this post was written, 31 cases of the disease have been confirmed in the west African nation. Of those confirmed to have been afflicted, nine have died.

Oh, and three individuals confirmed to have contracted the disease, two of which who were showing significant symptoms, managed to escape quarantine and mingle with an unknown number of people.

From the Washington Post:

In a briefing in Geneva, Jean-Clement Cabrol, a doctor who had just returned from Congo, said "the patients were in the active phase of the disease, vomiting" when their families removed them from the hospital, put them on motorcycles, and took them to a religious gathering of 50 people. Ebola is contagious through bodily fluids, and both patients, who were at an acute phase of the illness, died within hours.

Those two were among the three Ebola patients who left a hospital isolation ward and reentered the general population, according to the Doctors Without Borders mission in the Congolese city of Mbandaka.

That two of the patients, at the height of their power to infect others, opted to leave the quarantine that they’d been put under reads like something monstrous. But it couldn’t be more human. In their final hours, the pair, knowing that death couldn’t have been closer, turned to the comfort of their families and their faith, hoping that it would be a balm against the unspeakable misery that they must have been in.

The latest Ebola outbreak in Congo has moved from the rural area in which is was first discovered to Mbandaka: a city home to approximately one million people. That the disease has spread to an area with such a dense population is extremely troubling all on its own. Add to this the fact that Mbandaka is a major transportation hub with an airport, river traffic and direct transport options to Kinshasa, Congo's capital city, and you've got a scenario with the potential to keep World Health Organization personnel awake at night.

From the BBC

Forty-two people have now been infected and 23 people are known to have died.

Confirmed, probable and suspected cases of Ebola have been recorded in three health zones of Congo's Equateur province, the World Health Organisation (WHO) said.

The WHO's Peter Salama said health workers had identified 430 people who may have had contact with the disease and were working to trace more than 4,000 contacts of Ebola patients, who had spread across northwest Congo.

As part of efforts to stem the spread of the often deadly disease, drug manufacturer, Merick, shipped 4,000 doses of an unlicensed Ebola vaccine to Congo that was proven to have been effective in a previous outbreak of the disease in West Africa. There's just one problem: the vaccine needs to be stored between -60 and -80 Celsius. In a first world country, that mightn't be an issue--we've the facilities and infrastructure to make chilling the vaccine to those temperatures a piece of cake. Read the rest

The Centers for Disease Control & Prevention tweeted this image with the question: "Can you spot all 5 ticks in this photo?" Of course ticks generally don't hang out in pastries. The point was just to show how difficult it can be to spot ticks. But apparently the thought (and image) of a tick-infested muffin grossed out many Twitter users. The CDC apologized with, of course, a pun about ticking people off.

Anyway, here is the CDC's guide to "Avoiding Ticks."

Sorry we ticked some of you off! Don't let a tick bite ruin your summer. Protect yourself: https://t.co/zT2cMR2kKW.

If you enjoyed British supermarkets' bleach-dipped rotten turkeys, perhaps you like to try their antibiotic-resistant superbug-infested chickens.

The FSA has also noted that the proportion of campylobacter-infected chickens which showed resistance to key antibiotics, in this case ciprofloxacin, “has increased significantly” compared with a previous survey of chickens sold at retail 10 years ago. More than 4,000 samples were tested, then samples of smaller numbers exhibiting campylobacter infections retested to detect whether they carried bacteria resistant to the key antibiotics. Ciprofloxacin resistance was identified in more than half of the samples of one form of campylobacter tested, 237 out of 437 tests on Campylobacter jejuni, and in nearly half (52 out of 108) of another strain, Campylobacter coli.

The results were taken by experts to show that the use of antibiotics to treat farm animals is giving rise to the spread of resistant bacteria, which can have major effects on human health because one of the main methods of transmission to many strains of resistant bacteria is through contact with livestock in the food chain. While proper hygiene practices and thorough cooking can kill the bugs, any lapses can result in serious infection.

One approach to fight mosquito-borne diseases is to introduce huge numbers of sterilized male mosquitos to beat out the wild males in competition for female mosquitos. The challenge is that it's expensive to airdrop the mosquitos from airplanes and often difficult to traverse developing nations by ground. Now, WeRobotics has prototyped a drone that carries hundreds of thousands of mosquitos and releases them at just the right moment. The first experiments in South or Central America will take place in the next few months. From IEEE Spectrum:

The goal is to pack as many mosquitoes as possible into the drone. However, clumping is a problem because the insects form “a big collection of legs and wings,” he says. The trick, according to Klaptocz, is to keep them inside a precooled container: “Between 4 °C and 8 °C, they’ll fall asleep, and you can pack them up fairly densely.”

It’s also important to control the release of the mosquitoes, rather than dumping them out all at once. “We tried different systems to get the mosquitoes out of the holding canister, including vibrations and a treadmill,” he says. “Right now, we’re using a rotating element with holes through which individual mosquitoes can fall.” Once the mosquitoes fall out of the canister, they spend a few seconds in a secondary chamber warming up to the outside air temperature before exiting the drone, to make sure they’re awake and ready to fly.

Oriental Rat Flea

(Xenopsylla cheopis)

SIZE: Up to 1/6 in (4 mm)

FAMILY: Pulicidae

HABITAT: Near rats, their primary food source

DISTRIBUTION: Worldwide, particularly tropical and subtropical climates, but some temperate zones as well

MEET THE RELATIVES: The cat flea, Ctenocephalides felis, is a relative, as is the dog flea C. can is—but in the United States, it is primarily the cat flea that preys on both cats and dogs. They are known to transmit tapeworms.

On an autumn day in 1907, two brothers in San Francisco found a dead rat in the cellar. Inspired by their father, an undertaker, they decided to find a coffin for the rat to give it a proper funeral.

When they ran home for dinner that night, the boys brought along a souvenir of their adventures—bloodthirsty fleas, starved for a meal after their rat host had died. Along with the fleas came a deadly disease—the plague.

The rat flea would prefer to leave humans, cats, dogs, and chickens alone, but when rat populations experience a massive die off—as they do during epidemics of the plague—the fleas turn to other warm-blooded creatures for their food. This is exactly what happened to those two unfortunate boys. Within a month, the plague had killed their parents but spared the boys, leaving them orphans. Read the rest

Shu Lam, a 25-year-old PhD student at the University of Melbourne's School of Engineering, has developed a polymer that rips apart the cell walls of superbug strain bacteria.

From Science Alert:

The polymers - which they call SNAPPs, or structurally nanoengineered antimicrobial peptide polymers - work by directly attacking, penetrating, and then destabilising the cell membrane of bacteria.

Unlike antibiotics, which 'poison' bacteria, and can also affect healthy cells in the area, the SNAPPs that Lam has designed are so large that they don't seem to affect healthy cells at all.

"With this polymerised peptide we are talking the difference in scale between a mouse and an elephant," Lam's supervisor, Greg Qiao, told Marcus Strom from the Sydney Morning Herald. "The large peptide molecules can't enter the [healthy] cells."

At least 90 people have been hospitalized from an anthrax outbreak in Russia, including 50 children. Eight are confirmed as infected with anthrax. Doctors believe at least 6 patients have the more virulent intestinal form of the disease, which killed one boy, age 12. Authorities say it's the first fatal anthrax outbreak in Russia in more than 75 years. Read the rest

Approximately 350,000 people in the US are diagnosed with gonorrhea each year. According to the CDC, it may soon be untreatable. Currently, the sexually-transmitted disease, not-so-fondly known as The Clap or The Drip, is treated with two antibiotics, azithromycin and ceftriaxone. Data is currently showing a rise in gonorrhea samples that are resistant to those drugs.

Companies are developing new antibiotics but could be "years away," says CDC medical epidemiologist Robert D. Kirkcaldy.

"We think … it’s a matter of when and not if with resistance,” he says. “This bug is so smart and can mutate so rapidly.”

The Centers for Disease Control and Infection reported the first confirmed case of Zika transmitted from a woman to a man during sex. Previously, they thought that the disease was only likely to be sexually-transmitted from a male to female or male to male. The CDC will soon update their advisory "for sexually active people in which the couple is not pregnant or concerned about pregnancy and for people who want to reduce personal risk of Zika infection through sex." From CNN:

A non-pregnant woman in her 20s had unprotected vaginal sex with a male partner on the day she returned from travel to a country where Zika is circulating. The next day, she came down with Zika-like symptoms, including fever, rash, fatigue and muscle pain, along with numbness and tingling in her fingers and toes. On day three, she visited her primary care doctor, who took blood and urine samples, and sent them off to the NYC health department. Both tested positive for the virus.

On day seven after intercourse, her male partner, also in his 20s, began to show the same typical signs of Zika, such as fever, rash, joint pain and red eyes, despite the fact that he had not traveled outside the United States for more than a year...

While this is the first documented case of female to male sexual transmission, it's not the first clue that the Zika virus might be hiding in the female genital tract. A case report published this week in The Lancet Infectious Diseases journal tells the story of a 27-year old Guadeloupean woman who came down with Zika in May.
