A minute of loud talking can generate more than 1,000 coronavirus-laden droplets that linger in the air for 8 minutes, new research shows

Just one minute of loud speech can produce over 1,000 coronavirus-containing droplets, a new study found.

These droplets can linger in the air for eight-plus minutes, presenting a "likely mode of disease transmission," the study authors said.
The research also suggests that louder speech produces a higher number of droplets.

Talking loudly produces enough droplets to transmit the coronavirus to others, a new study confirms.

Given that one milliliter of oral fluid contains approximately 7 million copies of the coronavirus (according to previous research), the authors of the new study determined that speaking loudly for just one minute can emit more than 1,000 virus-containing droplets. Their work, published in the journal Proceedings of the National Academy of Sciences, also shows that those droplets can then remain in the air for eight minutes or longer.

While it's well understood now that the coronavirus (whose clinical name is SARS-CoV-2) can spread through droplets from coughs and sneezes, the study underscores the threat posed by asymptomatic and presymptomatic carriers â€” infected people who don't feel sick but can still pass along the virus.

"Speech droplets generated by asymptomatic carriers of SARS-CoV-2 are increasingly considered to be a likely mode of disease transmission," the researchers wrote.

The study also found that louder speech produces a higher number of droplets, though the authors noted that"there is a substantial probability that normal speaking causes airborne virus transmission in confined environments."

That's consistent with a recent CDC analysis of a coronavirus outbreak at a choir practice in Washington state. Of the 61 attendees, 33 tested positive and another 22 developed suspected cases.

"The act of singing, itself, might have contributed to transmission through emission of aerosols, which is affected by loudness of vocalization," the CDC report said.

The new study found that droplets emitted via speech shrink to between 20% and 34% of their original size after they're released into the air. That slows down the speed at which they fall to ground, meaning they can remain in the air for several minutes.

The findings come as states begin lifting lockdowns, allowing businesses to reopen and permitting some social gatherings. In some places, unmasked crowds are defying social-distancing guidelines, sparking concerns about new outbreaks.

"We're not reopening based on science," Dr. Thomas Frieden, a former director of the Centers for Disease Control and Prevention, told The New York Times. "We're reopening based on politics, ideology, and public pressure. And I think it's going to end badly."

Pakistan's Ferozsons to begin producing COVID-19 drug remdesivir

Reuters

15 May 2020

ISLAMABAD (Reuters) - Pakistan will soon start production of the antiviral drug remdesivir, which has shown promise in treating the novel coronavirus, the countryâ€™s top health official and a pharmaceutical companyâ€™s chief executive announced on Friday.

Production should start â€œwithin weeks,â€ said Osman Khalid Waheed, the chief executive of Ferozsons Laboratories Ltd, which will produce the drug. He spoke at a news conference alongside Pakistanâ€™s de facto health minister, Zafar Mirza.

â€œPakistan will be among the first three countries in the world where it will not only be produced but will also be exported to the whole world,â€ Mirza said. It will be exported to 127 countries, he said.

Remdesivir, a drug developed by Gilead Sciences (GILD.O), has grabbed attention as one of the most promising treatments for COVID-19, the respiratory disease caused by the novel coronavirus, which has killed more than 300,000 people.

To expand its access, Gilead said it signed non-exclusive licensing pacts with five generic drugmakers based in India and Pakistan, allowing them make and sell remdesivir for 127 countries.

â€œIt is a commitment by us and Gilead that this medicine could be produced at minimum cost and make it most accessible,â€ Waheed said.

Pakistan has recorded 37,218 COVID-19 cases and 803 deaths. Lockdowns to curb the diseaseâ€™s spread are forecast to will cause the countryâ€™s economy to shrink 1% to 1.5% in 2020.

Despite a rising rate of infection, Pakistan began lifting those lockdowns last week, primarily to avert an economic meltdown.

Coronavirus becoming much less lethal, virus is losing its 'potency,' top doctor reveals

31 May 2020 23:13

The coronavirus has become much less lethal and the virus is losing its "potency," a top Italian doctor has said, Reuters reported.

Dr. Alberto Zangrillo, the head of the San Raffaele Hospital in Milan â€” one of the areas in Italy hardest hit by COVID-19 â€” explained the evolution of the virus is extremely positive.

"In reality, the virus clinically no longer exists in Italy," Zangrillo told RAI television, Reuters reported.

"The swabs that were performed over the last 10 days showed a viral load in quantitative terms that was absolutely infinitesimal compared to the ones carried out a month or two months ago," he explained.

Although daily COVID-19 cases continue to rise, daily deaths are steadily decreasing after reaching a peak in mid-April. The increase in positive cases reflects mass testing across the globe, not a virus that is rapidly spreading. Italy, specifically, now averages fewer than 100 COVID-19 deaths per day after becoming the global epicenter just two months ago.

The decrease in potency means nations should reopen, Zangrillo said.

In fact, the doctor said there should be accountability for leaders who enacted such harsh lockdowns when the virus never lived up to the scientific predictions.

"We've got to get back to being a normal country," he said, Reuters reported. "Someone has to take responsibility for terrorizing the country."

Dr. Matteo Bassetti, the head of the infectious diseases clinic at a hospital in Genoa, corroborated Zangrillo's analysis.

"The strength the virus had two months ago is not the same strength it has today," he told the ANSA news agency, Reuters reported. "It is clear that today the COVID-19 disease is different."

COVID-19 NEW TREATMENT?: Ibuprofen Keeps Off Patients from Ventilators, Suggests the U.K. Hospital

3 June 2020 06:32

A new coronavirus treatment is now being tested in the United Kingdom. Ibuprofen, a painkiller that is said to ease the pain that COVID-19 patients experience in the hospitals, is now back in the hospitals. Experts from King's College and London's Guy's and St Thomas' hospital said that they are using painkillers to treat the patient's difficulty in breathing. Can it be helpful?

COVID-19 NEW TREATMENT?: Ibuprofen Keeps Off Patients from Ventilators, Suggests U.K. Hospital

BBC reported that hospitals in the U.K. are now using Ibuprofen to help COVID-19 patients. Aside from being cost-friendly with prices less than $5, experts from different well-known hospitals in the country, also believe that this painkiller may help positive COVID-19 patients of no longer using ventilators, to recover.

As explained, a test trial called Liberate will be made to ensure the effectivity of painkillers on the human body. Half of their patients in each British hospital will receive Ibuprofen.

Unlike the standard ibuprofen tablet sold in public, the hospitals will use a special formulation of the specific painkiller.

Didn't they say the opposite at the start of the pandemic?

Anyways, I've been taking ibuprofen and paracetamol everyday for months now. All because of a shattered tooth.

But that didn't stop me from getting ill a week after the Lockdown. I went down with a flu with body aches.

They were saying ibruprofen was harmful. I believe it to be harmful if your suffering from asthma and not able to take ibruprofen anyway. For the general public it make sense to take it for inflammation. Iâ€™ve had chest infection In the past ibruprofen has helped more than paracetamol. They both play different roles. Paracetamol more for pain relief.

Hopefully dentists will be opening up soon, Iâ€™ve heard of few ppl needing dental treatment. Wishing you a speedy recovery. Allah keep everyone well Aameen

Face masks to become mandatory on public transport in England, Transport Secretary announces
Face masks will be mandatory on public transport in England from June 15, Transport Secretary Grant Shapps has announced.

Speaking at the daily Government coronavirus press briefing, Mr Shapps said the rule will come into force on the same day non-essential shops re-open.

The public will have to provide their own face coverings and operators will have the powers to enforce the new rule.

Those who do not comply could be refused travel and may be fined.
Mr Shapps emphasised that this meant "the kind of face covering you can easily make at home" and not surgical masks.

At the Downing Street press conference Mr Shapps said: "I can announce that as of Monday June 15 face coverings will become mandatory on public transport.
"That doesn't mean surgical masks, which we must keep for clinical settings. It means the kind of face covering, you can easily make at home. There will be exemptions to these rules for very young children, for disabled people and those with breathing difficulties."

He said "we need to ensure every precaution is taken on buses, trains, aircraft, and on ferries".

"With more people using transport the evidence suggests wearing face coverings offers some - albeit limited - protection against the spread for the virus."

Apart from ulcers, chronic use of Ibuprophen and acetaminophen can cause damage to your kidneys and liver respectively. You should see if root canal treatment is feasible at this time otherwise you should get it extracted.

Jzk everyone for the positive and correct advice.

Yes I'm aware but the pain is intense at times.

Anyways, spoke to a dentist over the phone today for consultation and I've been told I could visis certain hospitals where they can help me or in the mean time I could try and purchase a temporary filling kit and see how that goes until the dentists are allowed to reopen.

So I've done just that and bought the kit.
