Connecting the dots

The measles are making a big comeback. 

The latest figures from the World Health Organization show that 2018 will be another (modern) record-setting year for the highly contagious yet easily preventable disease, with 301,702 suspected and confirmed cases worldwide through the end of October. But those represent just a fraction of the actual number of infections, as most cases in the developing world go unreported.

Late last month, the WHO and the U.S. Centers for Disease Control, published a report that found a 31 per cent rise in worldwide measles cases in 2017, estimating 110,000 deaths due to the disease, mostly children under the age of five. Reported cases have increased in five of the six world health regions, with only Western Pacific nations like Australia and Japan showing progress.

Targeted vaccination campaigns have reduced the number of measles deaths by 80 per cent over the past two decades, from an estimated 545,000 fatal cases in 2000. But vaccine coverage, which needs to be at 95 per cent to offer “herd immunity” and effectively end outbreaks of the disease, has stalled at around 85 per cent and has been falling in several countries. 

The reason is the anti-vaxxer movement, which has lately been gaining strength and support from populist governments who share their science skepticism.

A report in today’s Guardian newspaper captures the frustration of the European Union’s health commissioner, Dr. Vytenis Andriukaitis, at the close to 64,000 cases and 72 deaths across the continent so far this year.
“Not just me – all of scientific society is concerned – epidemiologists, paediatricians, infectious disease experts and a lot of health ministers,” he told the paper. “It is unimaginable that we have deaths because of measles – children dying because of measles. We promised that by 2020 Europe would be measles free.”

Immunization rates have fallen in places like Romania, Italy, Poland and France, as the internet continues to spread discredited concerns about the safety of the MMR vaccine and governments have made it easier for parents to opt out. And the number of cases across Europe have grown exponentially, from 5273 in 2016, to 23,927 last year and now almost triple that figure.

This year, Europe has experienced a particularly large measles outbreaks in Ukraine — 45,000 sickened — and sizeable ones in Serbia, Greece, and Albania among others, with cases now documented in 42 of its 53 nations. In fact, Europe now has more suspected and confirmed cases than Africa, and ranks second behind Southeast Asia, where India is currently experiencing the world’s worst outbreak.

But the problem is global.

Venezuela has seen a sharp spike in the measles in the midst of its economic and political meltdown, with more than 6,000 confirmed cases since the summer of 2017, as has neighbouring Brazil, which reports 9,800 cases. Madagascar has had more than 10,000 cases over just the past three months

And this week, Israel saw its second measles death in a month, as the nation grapples with an outbreak that has affected 2,690 people, resulting in 948 hospitalizations.

It has been a relatively quiet year for measles in North America, with 292 cases reported across the United States, and 29 in Canada — the latest leading to a public health alert this week in the Greater Toronto region

The highly contagious disease, which can be spread by coughs or sneezes, usually manifests itself with cold-like symptoms and a rash. But in certain cases it can cause serious and potentially deadly complications, including encephalitis, meningitis and pneumonia. 

Before the MMR vaccine became widely available in 1980, the measles used to kill 2.6 million people every year. And the the WHO estimates that the two dose treatment has prevented 21.1 million deaths since 2000.


Brexit fuels ‘brain drain’ fears

The U.K.’s departure from the EU has many scientists reconsidering their future, writes CBC London correspondent Thomas Daigle.

A born-and-bred Briton, Emma Bell hadn’t planned to leave the U.K.

That’s until Britain voted to leave the EU.

“I don’t understand why we’re intentionally self-destructing,” she said.

As a PhD-trained bioinformatician at Imperial College London, Bell uses computer programming to analyze DNA and identify cancer risks.

But she won’t be here for long.

She’s moving to Toronto by early February to work at the Princess Margaret Cancer Centre.

“I decided not to look for a position here in the U.K. because I have concerns about what life will be like and what my work will be like after March 29,” the day Brexit takes effect.

She’s not the only one.

Despite the British government’s assurances that it is managing the risks of a no-deal Brexit, scientists fear research material could be delayed at the border, international scientific cooperation could be held up and EU funding could vanish.

Nearly all London-based scientists (97 per cent) who responded to a recent survey said they believe a “hard” Brexit would be bad for their field. More than 1,000 staff took part in the study at the Francis Crick Institute, the country’s biggest biomedical research lab.

Jasmin Zohren says she took the 2016 vote “quite personally at the time.” A sex chromosome biology researcher at the Crick, Zohren is considering a move back to her native Germany once her contract runs out.

She predicts Brexit with no deal would lead to “chaos.”

“No one knows what’s going to happen.”

In just over three months, Britain is set to leave the European Union. But many uncertainties remain for the scientific community. The CBC’s Thomas Daigle met with a scientist who is moving to Canada because of Brexit. 2:17

5,800 test positive, 74 die of coronavirus at least 14 days after getting fully vaccinated

Published

on

By

(Natural News) The Centers for Disease Control and Prevention (CDC) on Thursday, April 15, confirmed some 5,800 breakthrough coronavirus (COVID-19) cases in the U.S.

A breakthrough COVID-19 case is defined as someone who has detectable levels of SARS-CoV-2 – the virus that causes COVID-19 – at least 14 days after getting fully vaccinated against the disease.

Nearly 400 breakthrough cases required treatment at hospitals and 74 died. A little over 40 percent of the infections were in people 60 years and above and 65 percent were female. About 29 percent of the vaccine breakthrough infections were reportedly asymptomatic. The figures were for cases through April 13.

CDC Director Rochelle Walensky told a congressional hearing on Thursday that the causes of the breakthrough cases are being probed. “Some of these breakthroughs are, of course, failure of an immune response in the host. And then some of them we worry might be related to a variant that is circulating. So we’re looking at both,” she said.

The CDC is monitoring reported cases “for clustering by patient demographics, geographic location, time since vaccination, vaccine type or lot number, and SARS-CoV-2 lineage.” It has created a national COVID-19 vaccine breakthrough database, where state health departments can enter, store and manage data for cases in their region.

Where available, respiratory specimens that tested positive for COVID-19 will be collected for genomic sequencing “to identify the virus lineage that caused the infection.”

Positive test less than two weeks after getting fully vaccinated is not a breakthrough case

The number of cases the CDC has identified does not include people who contracted COVID-19 less than two weeks after their final dose. The two-week marker is important, said infectious disease expert Dr. Amesh Adalja, senior scholar at the Johns Hopkins Center for Health Security.

A human body should have enough time to develop antibodies to SARS-CoV-2 after that timeframe. Before then, a person won’t necessarily have the built-up immunity needed to fight off an infection. According to Dr. Adalja, cases that occur before the two-week mark are not considered breakthrough cases.

Dr. Adalja also noted that more research is needed to determine if highly infectious variants of the virus are behind the breakthrough cases. “It is crucial to study breakthrough cases to understand their severity, their contagiousness and what role variants may be playing,” Dr. Adalja said.

More than 78 million people have been fully vaccinated against COVID-19 in the U.S. as of April 15.

“To date, no unexpected patterns have been identified in case demographics or vaccine characteristics,” the CDC said in a statement. “COVID-19 vaccines are effective and are a critical tool to bring the pandemic under control.”

But the CDC conceded that “thousands of vaccine breakthrough cases will occur even though the vaccine is working as expected.”

Dr. William Schaffner, an infectious disease specialist and professor at the Vanderbilt University School of Medicine, agreed with the CDC. “These vaccines that we’re using are fabulous but they’re not perfect,” he said. “At best, they’re 95 percent effective in preventing serious illness, but minor illnesses can occur.”

According to U.S. drug regulators, Pfizer’s COVID-19 vaccine is 95 percent effective in preventing infection. Moderna’s was shown in a clinical trial to be 94.1 percent effective while Johnson & Johnson’s was 66.9 percent effective. Only Johnson & Johnson vaccine, which received its emergency use authorization from the Food and Drug Administration (FDA) on Feb. 27, was tested when variants were circulating.

The percentages are based on results from vaccine recipients two weeks after the final vaccination.

Dr. Anthony Fauci, head of the National Institute of Allergy and Infectious Diseases, stated in a briefing last week that the breakthrough cases are not a cause for concern.

“I think the important thing is to look at what the denominator of vaccinated people is. Because it is very likely that the number of breakthrough cases is not at all incompatible with the 90-plus percent vaccine efficacy,” he said. “So I don’t think that there needs to be concern about any shift or change in the efficacy of the vaccine.”

More info needed before drawing conclusions from breakthrough cases

The percentage of vaccine breakthroughs in a population depends on multiple factors, including vaccine efficacy, the amount of virus circulating and the length of time since vaccination, according to Natalie Dean, an assistant professor of biostatistics at the University of Florida.

“I love to see small numbers as much as anyone, but know that numbers like this cannot be directly interpreted as a measure of vaccine efficacy (although I have a feeling they will be). We can only interpret them against a background rate in unvaccinated people,” Dean wrote on Twitter.

“Similarly, ‘most breakthroughs have been in elderly adults’ should not be read as the vaccine is less effective in elderly adults. The majority of vaccinations (and the longest amount of follow-up time) have been in elderly adults. Again, we need more info to interpret.”

More people died from fentanyl overdose than coronavirus in San Francisco last year

Published

on

By

(Natural News) More people died from fentanyl overdose than coronavirus (COVID-19) in San Francisco last year, a microcosm of a larger nationwide problem coinciding with the pandemic.

Data from San Francisco’s Office of the Chief Medical Examiner shows that 708 people were killed by fentanyl in 2020, an astonishing 118 times more since the introduction of the drug in the city just five years earlier.

That figure nearly tripled the 254 COVID-19 deaths recorded in the city for the whole of last year. More than 8 in 10 deaths were male, and just under half were white. People aged 55 to 64 made up nearly a quarter of the fatalities. Nearly 40 percent of the deaths occurred in open-air drug markets such as the Tenderloin and South of Market.

The number of overdose deaths in the city could have been far worse as more than 3,000 addicts suffering from an overdose were administered with naloxone, the lifesaving medication that reverses overdoses.

San Francisco’s death rate from fentanyl overdose continues to rise this year as 135 died by overdose in January and February, putting the city on pace for more than 800 deaths by the end of the year.

The city has become a significant part of a larger trend. The Centers for Disease Control and Prevention (CDC) released data on Wednesday, April 14, showing that more than 87,000 Americans died from drug overdose over the 12-month period that ended in September last year – the highest since the opioid epidemic began in the 1990s.

Lockdowns lead to more cases of drug overdose

The surge represents an increasingly urgent public health crisis that may be correlated to the government’s monotonous battle plan against the COVID-19 pandemic.

On March 19 last year, California became the first state in the U.S. to implement a stay-at-home order. It subsequently endured the longest lockdown of any state in the country.

The pandemic and accompanying lockdowns are believed to be partly responsible for the soaring number of drug deaths for obvious reasons. Lockdowns have badly disrupted the social services in the city, including drug addiction treatment. Drug experts say the isolation of the past 12 months is causing vulnerable residents to turn to opioids.

“We see the death and devastation getting worse right in front of us,” said Matt Haney, San Francisco Board of Supervisors member. “It’s an unprecedented spiraling, directly connected to the introduction of fentanyl in our city.”

Fentanyl first appeared on the streets of San Francisco in 2015. There were just six deaths from the synthetic opioid that year, 12 deaths in 2016 and 37 deaths in 2017. The figure skyrocketed when the drugs became widely available in the city in 2018.

Kristen Marshall, manager of the national drug harm reduction DOPE Project, noted the grim irony that while social isolation could save lives from COVID-19, it had undoubtedly contributed to the number of overdose deaths.

“Isolation is also the thing that puts people at the absolute highest risk of overdose death,” she said.

Pandemic exacerbates rise in deaths from drug overdose

The number of deaths from drug overdose started rising in the months leading up to the coronavirus pandemic, making it hard to gauge how closely the two phenomena are linked. But the pandemic unquestionably exacerbated the trend. The biggest jump in overdose deaths took place in April and May when fear and stress were rampant, job losses were multiplying and the strictest lockdown measures were in effect.

Many treatment programs closed during that time while drop-in centers, which provide support, clean syringes and naloxone, cut back services.

The data released by the CDC shows a 29 percent rise in overdose deaths from October 2019 through September 2020 compared with the previous 12-month period. Illicitly manufactured fentanyl and other synthetic opioids were the primary drivers, although many fatal overdoses have also involved stimulant drugs like methamphetamine.

Unlike in the early years of the opioid epidemic, when deaths were largely among white Americans in rural and suburban areas, the current crisis is affecting Black Americans disproportionately.

“The highest increase in mortality from opioids, predominantly driven by fentanyl, is now among Black Americans,” Dr. Nora Volkow, the director of the National Institute on Drug Abuse, said at a national addiction conference last week.

“And when you look at mortality from methamphetamine, it’s chilling to realize that the risk of dying from methamphetamine overdose is 12-fold higher among American Indians and Alaskan Natives than other groups.”

Dr. Volkow added that more deaths than ever involved drug combinations, typically of fentanyl or heroin with stimulants.

“Dealers are lacing these non-opioid drugs with cheaper, yet potent, opioids to make a larger profit,” she said. “Someone who’s addicted to a stimulant drug like cocaine or methamphetamine is not tolerant to opioids, which means they are going to be at high risk of overdose if they get a stimulant drug that’s laced with an opioid like fentanyl.”

The Drug Enforcement Administration (DEA) supported Dr. Volkow’s claim, saying that transnational criminal organizations cause a spike in overdoses by mixing fentanyl into illicit narcotics.

According to the DEA, Mexican cartels often purchase the drug components in China and use human mules to smuggle the narcotics to lucrative drug markets north of the border.
