In 2009 we were hit with the H1N1 strain of the swine flu. It triggered widespread vaccinations. More than 120 people died in Ontario. And now it’s back. Dr. Bryna Warshawsky, a medical director with Public Health Ontario, tells us what we need to know about this year’s strain. 8:31 

In 2009, Ontario was hit with a strain of swine flu called H1N1. It triggered widespread vaccinations. More than 120 people died in the province. Now it’s back and appears to be hitting children harder than the flu usually does.

Dr. Bryna Warshawsky, a medical director with Public Health Ontario, tells us what we need to know about this year’s strain. She spoke with the CBC’s Conrad Collaco about this year’s flu season and how H1N1 made a comeback. You can read an abridged and edited version of the interview or listen to the full audio interview by hitting the play button above.

How does this year’s version compare to the one we were so worried about in 2009?

It’s fairly similar. The difference is that in 2009 that was the first time that strain had circulated. As a population we had very little immunity, therefore it affected a large number of people, especially younger people. Since then, that strain has circulated a number of times and we have been vaccinating every year against that strain. We have more immunity now, so fewer people are getting ill.  

What about those of us who never got vaccinated? Or who have never had a flu shot before?​

It’s definitely not too late to get the influenza vaccine. It takes about two weeks for the flu shot to reach its maximum effectiveness. We know H1N1 will probably circulate for a number of weeks into the winter season. We often see an influenza B strain. That often happens later in the winter. Getting vaccinated now will help prevent that strain. For next year, the best time to be vaccinated is in late October/early November. 

We don’t really know why influenza does what it does …  Last year we saw influenza A and influenza B circulating at exactly the same times.– Dr.  Bryna   Warshawsky , Public Health Ontario 

Those are suggestions for prevention. What do you suggest for treatment?   

Most people with influenza will get better on their own. People should seek medical care if they are feeling particularly ill. However, for some people there is treatment. It can make us feel better and may prevent some of the complications like pneumonia. That medication is particularly important for people who are older or people who have underlying medical conditions, or for young people or for pregnant women. Those people should consult with their health care provider.  

How did the H1N1 strain of the swine flu make a come back?

H1N1 has circulated in a few years since the 2009 pandemic. Every year we tend to get one A strain followed by one B strain. There are two A strains that can cause problems. H1N1 is one and another one is called H3N2. In any given season one of them circulates. This year for some reason in Ontario we’re seeing a bit of both. We don’t really know why influenza does what it does. Generally we have one A strain followed by one B strain.   

What else do we know about this year’s flu in Ontario?

We started a bit later than the rest of the country. This year we seem to have been increasing over the past number of weeks. Luckily we don’t seem to have peaked over the holidays which can often be a problem for out health care system. We haven’t yet hit our peak for flu season.  

Are we seeing a rise in the number of children hit by the flu in Ontario?

We don’t have specific data for Ontario but we do know that H1N1 does cause illness predominantly in younger children and young adults. We can expect to see a similar profile as what is being seen in the rest of the country.

Flu can be unpredictable. Last year we saw influenza A and influenza B circulating at exactly the same times. It’s definitely not too late to get the influenza vaccine. It takes about two weeks for the vaccine to reach its effectiveness. There will probably be H1N1 circulating following that two weeks.   

The more people that are vaccinated reduces the chance of spreading influenza. When you are vaccinated you are less likely to pass infection to others, particularly to those who are at risk for the complications of influenza like the elderly, people with underlying medical conditions, young children and pregnant women. For those people, it’s very important for them to be vaccinated and for the people around them. If you are a young, healthy person, by being vaccinated you can help prevent influenza from being spread to people more at risk of complications.

Herbal remedies: Saw palmetto for hair loss prevention

Editor

Published

on

By

(Natural News) Saw palmetto is a small, shrub-like palm endemic to the United States. Known for its medicinal properties, saw palmetto has been used for centuries to treat reproductive issues and hormonal imbalance.

Today, saw palmetto is used as an ingredient in many hair growth products and supplements, as it is thought to prevent hair loss. This could be due to saw palmetto’s influence on the hormones that dictate hair growth.

Saw palmetto for hair loss

There is evidence to suggest that saw palmetto can help treat hair loss and prevent its occurrence. According to a 2012 study, saw palmetto could inhibit 5-alpha reductase (5-AR). 5-AR converts testosterone, a male sex hormone, into a more potent hormone called dihydrotestosterone (DHT).

Research shows that high levels of DHT can shrink hair follicles and result in hair loss. DHT also makes it harder for hair follicles to grow new hair once the old hairs fall out. By inhibiting 5-AR, saw palmetto blocks the conversion of testosterone to DHT.

In another 2012 study, researchers evaluated the effects of saw palmetto supplementation in men with mild or moderate androgenetic alopecia, or male-pattern baldness. One group received 320 milligrams (mg) of saw palmetto every day for two years, while another group took one mg of finasteride, a conventional drug used to treat hair loss.

The results showed that 38 percent of participants who supplemented with saw palmetto experienced improvements in hair growth, compared to 68 percent of those who supplemented with finasteride.

While the experiment showed that finasteride was more effective, the researchers noted that saw palmetto may be less likely to work in people with more severe cases of hair loss. More research is needed to confirm this.

Saw palmetto is available in several forms, including oral supplements and hair care products like conditioners and shampoos.

Due to limited research on the use of saw palmetto for hair loss, there is no official recommended dosage for it. That said, a study published in the Journal of Cutaneous and Aesthetic Surgery cited a recommended dosage of 160 mg twice daily for saw palmetto tablets. Researchers often use this dosage when studying with saw palmetto.

Take note that saw palmetto has been reported to sometimes cause mild side effects, such as headaches and stomachaches. If in doubt about using saw palmetto, consult a natural health practitioner.

Other natural remedies for hair loss

Hair growth depends on several factors, including a person’s genetic makeup. Still, some home remedies might help prevent hair loss and/or encourage hair growth. These remedies include:

  • Jojoba oil – Jojoba oil helps nourish hair follicles without leaving any residue behind. It also stimulates hair cells to grow faster.
  • Aloe vera – Aloe vera helps get rid of sebum buildup in the scalp. Sebum is a natural oil that helps keep the scalp moisturized. It can build up on the scalp and clog hair follicles due to poor hair hygiene.
  • Garlic – The pungent compounds in garlic help increase blood circulation in the scalp, which stimulates hair growth. These compounds also stimulate the synthesis of collagen, a protein that gives structure to hair.
  • Onion – Like garlic, onions boost blood flow in the scalp for better hair growth.
  • Licorice root – Licorice root helps relieve dry and irritated scalp. It also strengthens weak follicles.
  • Rosemary oil – Rosemary oil has antiseptic properties. It is ideal for treating scalp issues that slow hair growth, such as dandruff and bacterial infections.
  • Coconut milk – Coconut milk helps moisturize a dry scalp, which is a leading cause of hair loss.
  • Apple cider vinegar – Apple cider vinegar works as a clarifying agent, ridding the scalp of extra sebum and other residues that can clog hair follicles and inhibit hair growth.

Some hair loss is natural. But for mild to moderate cases of hair loss, it might help to use herbal remedies, such as saw palmetto, to strengthen hair or encourage hair growth.

Scientist that condemned coronavirus lab leak theory admits he squashed it to protect Chinese scientists

Editor

By

(Natural News) An American scientist who criticized theories that the Wuhan coronavirus (COVID-19) might have accidentally escaped or leaked from a Chinese laboratory has admitted that he was denouncing the idea in order to protect Chinese scientists.

Dr. Peter Daszak, the president of the EcoHealth Alliance, a New York-based nongovernmental organization that conducts scientific and policy research regarding emerging diseases, led an endeavor in February 2020 to quash any kind of suspicion that COVID-19 might have accidentally escaped from the Wuhan Institute of Virology, a research and academic institution supported by the Chinese state.

This culminated in a statement published in the prestigious medical journal The Lancet that condemned the “conspiracy theories suggesting that COVID-19 doesn’t have a natural origin.”

The Lancet article was written during the very early stages of the global pandemic, during a time when there wasn’t any kind of rigorous research on the origins of the virus.

Daszak further reiterated his support for China in a statement released on Feb. 6, stating that he stands with other scientists to “strongly condemn conspiracy theories suggesting that 2019-nCoV does not have a natural origin. Scientific evidence overwhelmingly suggests that this virus originated in wildlife, as have so many other emerging diseases.”

In June, Daszak also wrote an opinion piece for the Guardian titled: “Ignore the conspiracy theories: scientists know COVID-19 wasn’t created in a lab.”

But on Friday, Jan. 15, Daszak’s spokesperson told the Wall Street Journal that his statement, which has been used to silence anybody with a dissenting opinion regarding the origins of the coronavirus, was published to protect Chinese scientists from criticism.

The Lancet letter was written during a time in which Chinese scientists were receiving death threats and the letter was intended as a showing of support for them as they were caught between important work trying to stop an outbreak and the crush of online harassment.”

WHO team heads to Wuhan to probe virus origin

The situation surrounding Daszak’s initial statements and his sudden retraction are being compounded by the fact that the doctor is part of an international 15-member team of experts sent by the World Health Organization (WHO)to Wuhan to figure out the origins of the coronavirus.

According to the WHO, the team’s official mission is to determine how, where and when the virus crossed from animals to humans.

Daszak has been tweeting about the mandatory quarantine period he and his team are going through. During day four of quarantine, he said that the day, like the previous days, is “packed” with virtual meetings.

Peter Ben Embarek, team leader and WHO food safety and animal diseases expert, said that the team will be granted permission “to move around and meet our Chinese counterparts in person and go to the different sites that we want to visit,” once they’re done with the mandatory quarantine period.

It is unclear whether the WHO team will be looking into the Wuhan Institute of Virology and the theory that the coronavirus was engineered. Embarek has stated his desire to visit the “famous Wuhan market” to try and determine “everything that went in and out” of there in the weeks before the first confirmed cases.

Embarek is referring to the Huanan Seafood Wholesale Market in Wuhan, where many wild animals were often sold. This place is being investigated as a likely setting for the supposed “animal-to-human jump” of the coronavirus, or a place where that jump was accelerated.

“We know the virus originated in bats at some point, and then we know that human cases appeared in Wuhan in December 2019,” said Embarek. “But what happened in between, how many other animal species were involved in between, and where, remain to be found in more detail.”

“We don’t really know what happened in that period of time, and that’s what we are looking out for.”

Questions will remain regarding the role of the institute in the initial outbreak; questions that will continue to linger if WHO team does not conduct its investigation.

Then-Secretary of State Mike Pompeo even said that the government has reason to believe that several researchers working for the institute “became sick in autumn 2019, before the first identified case of the outbreak, with symptoms consistent with both COVID-19 and common seasonal illnesses.”

Pompeo said that this calls into question the claims made by Shi Zhengli, the institute’s senior researcher on bat-related viruses, that there had been “zero [COVID-19 or SARS-related] infection” among the institute’s student body and staff.

Pompeo noted that the possibility of an “accidental infection” in a lab is more likely than people might think, especially considering that such an incident has already occurred in China. In 2004, a SARS outbreak in Beijing that infected nine people and killed one originated in a research facility.

California healthcare workers suffer severe allergic reactions following coronavirus vaccination

Editor

Published

(Natural News) Six healthcare workers suffered allergic reactions after getting a shot of Moderna coronavirus vaccine in San Diego, California. Their symptoms were considered severe and required medical attention.

The doses administered to the six healthcare workers were part of the Moderna Lot 041L20A distributed to 287 providers across the state earlier this month. That batch of shipment, which arrived in California between Jan. 5 and Jan. 12, is composed of 330,000 shots.

Moderna said in a statement that it is cooperating with California’s health department to investigate the allergic reactions.

“Moderna acknowledges receiving a report from the California Department of Public Health (CDPH) that a number of individuals at one vaccination center were treated for possible allergic reactions after vaccination from one lot of Moderna’s Covid-19 vaccine,” the statement read. “The company is fully cooperating with CDPH in investigating these reported adverse events.”

Dr. Erica Pan, California’s state epidemiologist, said Sunday, Jan. 17, that providers should err on the side of caution and stop using the doses until federal, state and company officials finish an investigation.

“Out of an extreme abundance of caution and also recognizing the extremely limited supply of vaccine, we are recommending that providers use other available vaccine inventory and pause the administration of vaccines from Moderna Lot 041L20A until the investigation by the Centers for Disease Control and Prevention (CDC), Food and Drug Administration (FDA), Moderna and the state is complete,” she said.

Monterey, Santa Clara and Santa Cruz have already paused distribution while two Covid-19 vaccine clinics have been canceled in Stanislaus County following the allergic reaction reports.

The delay was a huge blow to California’s vaccine distribution efforts. California currently has the second highest number of coronavirus cases per capita in the United States, with Los Angeles being a particular hotspot.

All cases of apparent allergic reactions occurred at San Diego County’s drive-through mass vaccination site at Petco Park. No other providers have reported allergic reactions to vaccines administered from the same batch of doses.
