Coronavirus Updates: Can Asymptomatic Carriers SpreadCOVID-19?

New evidence suggests asymptomatic transmission is less likely than previously thought.

On Monday, a representative from the World Health Organization called asymptomatic transmissions of the coronavirus "very rare." This was quickly bolstered by conservative lawmakers to call for the end of social distancing guidelines and the mandatory wearing of face masks. Many health experts and scientists questioned WHO's statement, citing a lack of evidence.

Today, WHO has walked back their original statement, clarifying that the observation "was based on a relatively small set of studies," and, "Evidence suggests people with symptoms are most infectious, but the disease can be passed on before they develop."

So What Happened?

Essentially, the original statement was referring to a small set of data from various countries in instances where an asymptomatic case had been followed up and secondary infections among the asymptomatic person's contact had been sought out. This data suggested that infections among the people the asymptomatic person had come in contact with were "very rare."

The WHO emphasized today that there is no way of knowing if this trend is true on a global scale.

According to the BBC, the Director of the WHO's health emergencies program, Dr Michael Ryan, said he was "absolutely convinced" asymptomatic transmission was occurring, but "the question is how much."

What Exactly Does Asymptomatic Mean, Anyway?

According Dr Van Kerkhove, the WHO's head of emerging diseases, there are three categories within the designation of "asymptomatic."

  • People who never develop symptoms (asymptomatic)
  • People who test positive when they don't yet have symptoms - but go on to develop them (pre-symptomatic)
  • People with very mild or atypical symptoms who do not realise they have coronavirus
So, while people who never develop symptoms are unlikely to pass on the virus, it's impossible to know if someone who has tested positive is truly asymptomatic or merely pre-symptomatic. If they are pre-symptomatic, then they are more likely to pass on the virus.

Should I Continue to Social Distance and Wear a Mask?

Yes. There is still so much that experts don't know about the spread of COVID-19, so while some evidence may suggest the virus isn't as easily passed on by as many people as previously thought, that doesn't mean you won't contract the virus if you aren't careful.

We Shouldn't Be This Worried About Bernie Sanders' Health

It's time we stop acting like the leading Democratic candidate is the only old guy who's ever had a heart attack.

Whoever your pick might be in the 2020 Presidential Election, there's an overarching issue that's been largely prominent: the age of the Democratic front-runner, Bernie Sanders.

At 78, Sanders would be the oldest elected president in the country's history (a title currently held by Trump). The topic of his health became more hotly debated after he suffered a heart attack last October, resulting in him having two stents inserted. Though he bounced back to give one of his best debates yet that very same month, critics have been quick to cite Sanders' declining health as a hindrance to his electability. The backlash is getting even louder as Sanders claims he won't divulge his comprehensive health records. "We have released a detailed medical report, and I'm comfortable on what we have done," he said this week during a CNN town hall.

Sanders' campaign has released letters from three doctors who all asserted the senator is in good health. "I do not see a reason why he would not be able to function effectively in a high stress job," said Dr. Mary Ann McLaughlin, director of cardiovascular health and wellness at Mount Sinai Heart in New York. Why are Sanders' opposers so adamant that his health will fail him in office?

Yes, the senator is the oldest candidate in the race, but not by much: Michael Bloomberg and Joe Biden are 78 and 77 respectively, while Sanders' fellow progressive Elizabeth Warren is 70—the same age as Trump when he was elected. The health of Bloomberg, Biden, and Warren hasn't been scrutinized nearly as much as Sanders'. Sure, he might be the only one of the bunch who's suffered a heart attack, but that alone shouldn't be a disqualifier; notable politicians including President Dwight D. Eisenhower, President Lyndon Johnson, and Vice President Dick Cheney all proceeded with lengthy, successful careers in office despite suffering heart attacks early on.

A heart attack should not render an otherwise healthy candidate unfit for presidency, and Sanders' campaign has offered enough proof of his well-being. Our country's entire history has been predominantly dictated by old white men—why make an exception for someone who can actually instigate radical change?

Most Environmentally-Responsible Meat You Can Eat

Better meat options exist.

Every year, humans eat 70 billion animals around the globe, and 9 billion of them are killed in the U.S.

According to a recent article in The Guardian, the most significant way to lower your impact on the environment is cut out meat and dairy from your diet: "The new analysis shows that while meat and dairy provide just 18% of calories and 37% of protein, it uses the vast majority – 83% – of farmland and produces 60% of agriculture's greenhouse gas emissions."

This presents environmentally-conscious animal eaters with a stark choice: Give up eating animals, or give up on your beliefs. But there is a middle ground, which involves choosing options that have, if not a zero-impact, perhaps a lower one. Here is a list of choices, going from best to worst.

Chicken

For those who aren't ready to give up meat but want a more environmentally-friendly option, switching to chicken is one of the best choices. Slate explains that chickens produce a much lower amount of carbon dioxide than cows. Cows generate about four times more greenhouse gases than chickens. In addition, chickens only create two to four pounds of manure per pound of weight, which is less than the 35 to 65 pounds cows make per pound of beef, according to Slate. Experts recommend looking for free-range chickens raised without antibiotics.

Pork

Pork is a better environmental choice than beef because pigs produce about 50% less carbon dioxide than cows, according to the BBC. Pigs are also omnivores (they'll eat anything), and this is actually better for the environment than cows that require grass or grains. A hog can help reduce food waste by consuming vegetable scraps and other food that would have been discarded. Another positive is that pigs need less feed overall compared to cows.

Mussels

Technically, mussels aren't meat because they're categorized as seafood. However, they're an option for people who don't want to go vegan and still want a good source of protein. The BBC explains that mussels actually capture carbon dioxide, so they're an environmentally-responsible alternative and a better choice than farm-raised fish. They don't need to eat other food sources to grow because they filter nutrients from the water, so their impact is lower. Moreover, they don't contribute to pollution.

Meat-Buying Tips

Shoppers who are worried about the environmental impact of their meat purchases should consider the following tips. First, try to reduce the number of days per week that you eat meat. You can switch to meatless Mondays or make the weekends meat-free. Another option is to use meat alternatives like tofu more often when you cook. Look for free-range and organic meat products. Some other label names to watch for include cage-free or barn-roaming.

There are meat options that are more environmentally-friendly. Consider making chicken, pork, and mussels more frequently for dinner.

8 Recent Disease Outbreaks You Should Know About

The best way to minimize risk is to stay informed.

Modern medicine, especially vaccines, have drastically reduced the likelihood of getting infected by a deadly disease in first world countries.

But new strains, unvaccinated people, and other unforeseen factors can still pose a threat, and when an outbreak does occur, disease can spread like wildfire. This is especially true in third world countries, where access to medicine is lacking. These are just eight recent disease outbreaks you need to know about to keep yourself safe.

1. Yellow Fever - Nigeria

medium.com

Yellow Fever, named for the yellowing effect it causes on skin, is currently spreading in Nigeria's Edo State. The virus is mainly spread through mosquitoes. This outbreak is unusually large in scale and severity, especially considering it's coming at a time of year when many travelers vacation to Nigeria. The World Health Organization (WHO) is not currently recommending any travel or trade restrictions, but they do implore any potential travelers to get vaccinated against the virus.

2. Ebola Virus - Democratic Republic of the Congo

abcnews.com

An ongoing Ebola epidemic has been raging in the Democratic Republic of the Congo, with 16 new cases confirmed between December 27, 2018 and January 2, 2019. Ebola is incredibly deadly, causing bloody vomit and internal bleeding, and spreads easily through saliva, bodily fluids, and contact with contaminated surfaces. Since there is no current accredited vaccine for Ebola, travelers are recommended to seek medical advice beforehand.

3. Measles - New York

gannett-cdn.com

In 2019, confirmed cases of Measles have hit record highs in New York, at least dating back for a few decades. Measles is the most deadly vaccine-preventable virus, mainly affecting young children and resulting in a red, blotchy skin rash. The virus, which had been mostly irrelevant for decades due to vaccines, has been experiencing a global resurrection propelled by parents not vaccinating their children.

4. Hantavirus Disease - Republic of Panama

grancorenviro.com

Hantavirus disease has been ramping up in the Republic of Panama with 103 confirmed cases during 2018. Infection can progress to Hantavirus Pulmonary Syndrome (HPS), which is a fatal respiratory disease. The disease is primarily spread through rodents, and early treatment has a high success rate of mitigating lasting effects.

5. Typhoid Fever - Islamic Republic of Pakistan

medicalnewstoday.com

A drug-resistant outbreak of Typhoid Fever has recently been reported in the Islamic Republic of Pakistan. Typhoid Fever is a very serious disease that causes high fever, stomach issues, and in rare cases can result in internal bleeding and death. The illness is primarily spread through contaminated food and water, and the WHO notes that this outbreak highlights the importance of public health measures to prevent such spreads.

6. Candida Auris - US

infectioncontroltoday.com

A type of yeast, Candida Auris is a relatively new infection that has proven difficult to combat. In 2018 there were nearly 500 confirmed cases in the US, and the trend seems to be continuing into 2019. Unfortunately the infection is largely drug-resistant, hard to spot, and prone to outbreak within the healthcare community.

7. Influenza - U.S.

southernresearch.org

This past flu season, over 80,000 people died from influenza, giving 2017-2018 the highest influenza death toll in 40 years. This was partially a result of the flu vaccine not being as successful as in previous years. People are still strongly recommended to continue getting their yearly flu vaccine to prevent future outbreaks of preventable strains.

8. E. Coli - U.S.

internapcdn.net

In June of 2018, an E. coli outbreak linked to contaminated romaine lettuce killed 5 people in the US. This strain of E. coli produced life-threatening toxins in the body which caused severe diarrhea, amongst other illnesses. 197 people were affected in total, but luckily the outbreak was contained. Yet another outbreak of E.coli linked to California-grown romaine lettuce ended on January 9, 2019, this time infecting 62 people. Unfortunately, E. coli and Salmonella poisoning is a relatively common occurrence now, especially considering how understaffed the U.S. Food and Drug Administration is currently. The ongoing government shutdown has served to further this problem, making safe oversight of food a serious issue right now.

Ultimately, sometimes you can do all the right things and still get infected with a disease or illness. That being said, with access to modern medicine, it's important to take every possible precaution to avoid preventable outcomes. This means making sure you, your family, and your friends are properly vaccinated, as well as avoiding those who are not. It also means doing your research before traveling to prepare for any possible outbreaks. Should you follow those basic rules, your risk of infection will be at a minimum.

CDC Warns Untreatable Illness Is Afflicting U.S. Children

The rare condition is known to have polio-like symptoms, but no vaccine and no treatment.

An untreatable illness is afflicting young children at an alarming rate in the U.S. this year.

According to the Centers for Disease Control, 62 cases of acute flaccid myelitis (AFM) have been confirmed, spanning across 22 states. Last year, there were 33 confirmed cases across 16 states. To date, there are as many as 65 additional cases still under investigation in a total of 30 states. While the CDC is testing every confirmed patient in search of a cause for the flare of incidents this season, results offer no answers.

The CDC is raising concerns over the marked increase in the condition's occurrence since August 2014. On average, one in a million people in the U.S. contract AFM. The disease presents with polio-like symptoms such as weakness or sudden loss of muscle tone in the arms and legs. Other symptoms include fever or respiratory problems. Youth are particularly vulnerable to the illness; 90% of cases affect children under the age of 18, while the average age of patients is only 4 years old. The rare condition severely compromises the nervous system, particularly the gray matter surrounding the spinal cord, potentially causing paralysis or death. Although the disease is known to be caused by a virus, it's unknown why some people are more susceptible than others or why some patients recover quickly while AFM proves fatal to others.

NPR

Dr. Nancy Messonnier, director of the CDC's National Center for Immunization and Respiratory Diseases, confirms, "We have not been able to find a cause for the majority of these AFM cases." She suggests, "AFM may be caused by other viruses, including enterovirus, environmental toxins and a condition in which the body's immune system attacks and destroys tissue that it mistakes for foreign material."

Despite its likeness to polio, there is no vaccine to prevent AFM. No specific treatments or interventions have been established in the medical community. Current treatment plans only include palliative care and physical therapy for chronic nerve pain, as well as medical intervention in the event that nerve weakness renders patients incapable of breathing on their own. Antidepressants are also recommended to help a patient cope.

ABC News

The CDC is urging parents and caretakers to remain vigilant of possible AFM symptoms in young people. As for prevention, the health agency is left grappling, recommending general precautions similar to those against the flu: thorough hand-washing, staying up-to-date on other vaccines, and using insect repellent to protect against mosquito bites. "This is a pretty dramatic disease," Dr. Messonnier said. "This is a mystery so far, and we haven't solved it yet, so we have to be thinking broadly."

What the Monsanto Court Ruling Means for the Future

What's next for Monsanto?

Monsanto has been accused of not revealing the hazards of using its Roundup™ weed killer.

Research has shown a potential link between the glyphosate in Roundup and cancer. In addition, glyphosate may cause kidney and liver problems. Although an estimated 4,000 lawsuits have been filed against Monsanto, Dewayne Johnson is the first person to be awarded $289 million in damages after he developed terminal cancer, which he attributed to being exposed to Roundup as a school groundskeeper. What does this landmark lawsuit mean for the future?

More Lawsuits Against Monsanto

A federal judge has already ruled that lawsuits against Monsanto from 400 plaintiffs can move forward to trial. U.S. District Judge, Vince Chhabria, concluded that a jury should decide if glyphosate causes cancer in their cases. Ranging from landscapers to farmers, the plaintiffs claim that Roundup causes non-Hodgkin's lymphoma, which Monsanto denies. Considering Dewayne Johnson's successful case against Monsanto, it's reasonable to expect that the company's future will include hundreds and possibly thousands of lawsuits.

Bayer Will Appeal the Verdict

Bayer paid $66 billion to acquire Monsanto, and the merger will eliminate Monsanto's name. However, Bayer plans to appeal the $289 million verdict in the Dewayne Johnson case and wants a judge to reverse the jury's decision. If reversing the ruling fails, then Bayer plans to take the case to California appellate courts. In addition, Bayer has indicated it's not willing to settle out of court. It appears the company is prepared for years of lawsuits.

Roundup May Disappear From Store Shelves

Bayer is allegedly considering the option of removing Roundup from common gardening uses but may continue to sell it to farmers. This means that the average consumer may not be able to buy it in the future. It's important to note that the company hasn't confirmed these plans.

Roundup Bans May Increase

Roundup is already banned in several countries, and more may follow suit in the near future. Roundup is currently banned in Argentina, Belgium, El Salvador, Netherlands, and Sri Lanka. Germany and France have also announced their intention to ban the weed killer, and some stores have already started to remove it. In the United States, multiple cities and states (parts of Colorado, California, and Florida) around the country have glyphosate restrictions or bans.

Concerns About Glyphosate in Food Will Grow

The lawsuit against Monsanto and the bans around the world are making people more aware of Roundup. Concerns about glyphosate, the active ingredient in the weed killer, showing up in food are also on the rise. A recent report from the Environmental Working Group (EWG) found Roundup in popular cereals, granola, and oats. Even some of the organic products tested positive for glyphosate. About 75 percent of all the samples tested by EWG had levels that were higher than the group considers safe for children. The EWG is encouraging people to demand that the United States Environmental Protection Agency (EPA) restrict Roundup use.

The Dewayne Johnson v. Monsanto Company was the first case to go to trial, but it will not be the last. You can expect to see more Roundup lawsuits and bans in the future.

Trying to Pack a Healthy Lunch? Avoid Using These Items

Stay away from these lunch containers and packing items.

Once you've conquered the temptation of eating out for lunch every day, packing your own food seems like the perfect alternative. However, if you're packing certain items, then that brown bag lunch could be doing more harm than good. Before you start stuffing a lunchbox with cut vegetables and sandwiches, consider the following packing items you should avoid.

Where Do the Vitamins and Minerals In Your Supplements Come From?

The sourcing of many vitamin supplements is murky at best.

When exercise and nutrition coach Ryan Andrews was researching his story for Precision Nutrition on how vitamins and minerals in nutritional supplements are sourced, he ran into some interesting—and frankly, ironic—informational barriers.

"I emailed Nature Made about vitamin B-1," Andrews writes. "They said: 'We appreciate your questions concerning our supplements. Nature Made Vitamin B-1 is manufactured in a laboratory from chemicals. It is synthetically made in our manufacturing facilities in Southern California.'"

Is DEET Safe?

DEET has a bad reputation, but is it warranted?

It's summertime and mosquitoes are out in full force, invading barbecues and pool parties like Napoleon through continental Europe. In primitive times, mosquitos' reign of terror went unabated. They'd bite everyone, spreading disease and discomfort all over the globe. But eventually, humanity got fed up and in 1944 a man by the name of Samuel Gertler invented N,N-diethyl-meta-toluamide or DEET, a chemical compound designed to protect against mosquitoes, and other insects. At first, DEET was used exclusively by the military for jungle warfare, but it eventually made its way to our civilian population in the popular spray canisters we all know today. That said, people used to coat their houses with lead-based paint back when DEET was invented. Over the years, the bug repellant has caught a lot of flack for its potential toxicity. But is it really as dangerous as some people claim?

Exploring the controversies surrounding the Peace Corps

Volunteers look to change the world but the agency's practices have been debated for decades

In February 2013, 23-year-old Peace Corps volunteer Nick Castle died in a hospital at West China Hospital of Sichuan University of a gastrointestinal illness. He had fallen into a coma after feeling sick for months, losing weight and, finally, collapsing in Chengdu, the capital of the Sichuan province. Carrie Hessler-Radelet, the director of the Peace Corps in 2013, told the New York Times that the agency had been examining and revising its entire practice since the death of another volunteer in Morocco in 2009.

Deaths in the Peace Corps are not frequent, but they rightly call into question the program's training processes, medical resources, and the security of volunteers.
