Israel detects 1st case of COVID-19 Delta variant "AY4.2".

The first case of the new COVID-19 Delta variant "AY4.2" was detected in Israel on Tuesday (19th), the country's Ministry of Health said. 

This is the variant that was previously detected in several European countries, the ministry noted. It was diagnosed in an 11-year-old boy, who underwent a coronavirus test at Ben Gurion International Airport outside Tel Aviv, upon his return from Moldova.

"AY4.2", which some are calling “Delta Plus”, contains mutation that might gives the virus survival advantages.

WHO Global TB report for 2021.

The World Health Organisation (WHO) has released the ‘Global TB report for 2021, where it highlighted the effects of COVID-19 which led to a huge reversal in the progress of Tuberculosis (TB) elimination. The report also mentioned India as the worst-hit country in TB elimination, where the detection of new TB cases saw a huge impact in 2020.

A dramatic reduction of 20% TB cases were witnessed in 2020 as compared to 2019, ie; a gap of 4.1 million cases. The progress in TB detection has gone back to the levels of 2012, with India accounting for 41% of the total case drops in 2020.

Please note that direct comparisons between estimates of TB disease burden in the latest report and previous reports are not appropriate. The most recent time-series of estimates are published in this global TB report.

Covid-19 treatment Sri Lanka explores possibility of using Merck’s oral antiviral pill.

Sri Lanka is exploring the possibility of using the oral antiviral pill developed by the pharmaceutical giant ‘Merck’ for the treatment of COVID-19 patients, Daily Mirror learns.  Merck & Co Inc (MRK.N) which developed the pill has already applied for U.S. emergency use authorisation to treat mild-to-moderate patients of COVID-19. It is the first oral antiviral medication for Covid-19 patients.   

State Minister of Production, Supply and Regulations of Pharmaceuticals Prof. Channa Jayasumana requested Director General of Health Services Dr. Asela Gunawardane in writing on October 11 to submit to him the opinion of the experts’ panel on the use of this pill in the treatment of Covid-19 patients.   

The treatment which is called Molnupiravir reduces the risk of hospitalisation and death by half.  Already, several countries such as Malaysia, South Korea and Singapore scramble to strike a supply deal with Merck.  

Prof. Jayasumana also mentioned in his letter that the pill is prescribed in several countries at the moment. According to foreign media, Merck plans to double manufacturing capacity since there is a surging demand for its product.

First Malaria Vaccine Approved by W.H.O.

World Health Organization (WHO) is recommending widespread use of the RTS,S/AS01 (RTS,S) malaria vaccine among children in sub-Saharan Africa and in other regions with moderate to high P. falciparum malaria transmission. The recommendation is based on results from an ongoing pilot programme in Ghana, Kenya & Malawi that has reached more than 800 000 children since 2019.

The vaccine is developed by British drugmaker GlaxoSmithKline (GSK). Many vaccines exist against viruses and bacteria but this was the first time that the WHO recommended broad use of a vaccine against a human parasite. The vaccine acts against Plasmodium falciparum, one of five parasite species and the most deadly. The symptoms of malaria are fever, headaches, and muscle pain, then cycles of chills, fever, and sweating.

Chinese organic manure sample rejected due to contains of Bacillus Bacteria.

Due to the presence of Bacillus bacteria in the fresh sample of the Chinese organic fertiliser, the agriculture department has rejected the organic fertiliser from that country, Agriculture Director General Dr. Ajantha de Silva said.

He told the Daily Mirror that two tests have been conducted on the organic fertiliser samples. The results revealed that there is a serious issue with the bacteria which should not enter the country.

Therefore, the Ministry has decided to cancel the supplier's contract to import the Chinese organic fertiliser due to the above mentioned factor, Dr. Silva said.

With the rejection to bring this fertiliser, the farmers will not face any threats to their agricultural activities, as the Ministry granted permission to several private firms to import them, he said.

Every consignment of fertiliser that are imported into the country should be channeled  through out strict process. The Agriculture Department will never allow such organic fertilizer with harmful bacteria to enter the country.

He also said that no Chinese manure is being imported into the country categorised as organic fertiliser, and that will never happen, the DG confirmed.

COVID-19 pandemic cut life expectancy by most since World War Two.

The COVID-19 pandemic reduced life expectancy in 2020 by the largest amount since World War Two, according to a study published on Monday, 27th September 2021 by Oxford University, with the life expectancy of American men dropping by more than two years.

Life expectancy fell by more than six months compared with 2019 in 22 of the 29 countries analysed in the study, which spanned Europe, the United States and Chile. There were reductions in life expectancy in 27 of the 29 countries overall.

The university said most life expectancy reductions across different countries could be linked to official COVID-19 deaths. There have been nearly 5 million reported deaths caused by the new coronavirus so far, a Reuters tally shows.

There were greater drops in life expectancy for men than women in most countries, with the largest decline in American men, who saw life expectancy drop by 2.2 years relative to 2019.

In the United States, the rise in mortality was mainly among those of working age and those under 60, while in Europe, deaths among people aged over 60 contributed more significantly to the increase in mortality.

Scientists develop a 3D-printed microneedle patch.

Scientists have developed a tiny 3D-printed microneedle vaccine patch that could offer a pain-free alternative to needles.  

In trials on mice, it offered a 10-fold greater immune response and a 50-fold greater T-cell and antigen-specific antibody response compared with a needle in the arm. 

The polymer patch, which is smaller than a 5p coin, needs lower doses and could be mailed to people's homes and self-administered, eliminating the need for trained medical personnel. 

It also offers an 'anxiety-free' vaccination option for people who have a 'needle phobia', also known as trypanophobia, which is putting some off getting their Covid jabs. 

The researchers are yet to conduct clinical trials of the patch on humans, which could pave the way for a new way of administering vaccines in the future.  

The new vaccine patch has been developed by researchers at Stanford University and the University of North Carolina at Chapel Hill.

World Contraception Day - 26 September.

Every year on September 26th, World Contraception Day spreads awareness about contraception and safe sex. The day also teaches younger generations to make informed decisions about sexual health.

Many believe birth control is a fairly modern invention. However, men and women as far back as 3000 BC used various ways to prevent pregnancy. In 3000 BC, ancient Egyptian men had invented the first condom. IN 1850 BC, women were using a pessary as a way to prevent pregnancy. This contraceptive device was placed inside the vagina to kill sperm. The pessary contained a concoction of crocodile dung, honey, and sodium carbonate.

In 2007, 10 international family planning organizations came together to form World Contraception Day. They set a goal to promote safe, effective, and preferred family planning options and contraceptive methods. Additionally, 15 NGOs throughout the world, along with several scientific and medical societies, support this day.

WHO revises air quality norms for first time since 2005.

The World Health Organisation (WHO) has announced a tight revision in its air quality guidelines (AQG). This is the first revision in the global air quality by WHO since 2005. In the new guidelines, WHO has lowered the acceptable exposure levels to key pollutants, including ozone, nitrogen dioxide, sulfur dioxide, carbon monoxide and particulate matter (PM).

Under the new guidelines:

  • WHO has lowered acceptable thresholds for several pollutants, including PM 2.5. Now, PM 2.5 concentrations must remain below 15µg/m³.
  • According to the new limits, average annual PM2.5 concentrations should not be higher than 5 micrograms per cubic meter.
  • Air pollution kills at least 7 million people prematurely each year. The revised guidelines encourage countries to slash fossil fuel emissions.
  • These guidelines are not legally binding on countries. The reduced level of air pollution will improve the health of people.

Pfizer/BioNTech Company said data show COVID-19 vaccine safe and protective in kids.

Pfizer Inc (PFE.N) and BioNTech SE said on Monday (20th) their COVID-19 vaccine induced a robust immune response in 5 to 11 year olds, and they plan to ask for regulatory authorization as soon as possible to use the shot in children in that age range in the United States, Europe and elsewhere.

The companies said their two-dose vaccine generated an immune response in the 5-to-11 year olds in a Phase II/III clinical trial that matched what was previously observed in 16-to-25 year olds. The safety profile was also generally comparable to the older age group, they added.

Cuba becomes first country to vaccinate young kids against Covid-19.

Cuba started vaccinating children as young as two years old against covid-19 this week, becoming the first country in the world to inoculate toddlers. At least 12 young kids have died from covid-19 in Cuba this year, while there were no infant deaths from the disease in that country during 2020, according to the Miami Herald.

Cuba developed its own covid-19 vaccine, a two-shot regimen known as Soberana 2 that has an efficacy of 91.2% after a booster called Soberana Plus, according to studies in the country which haven’t yet been peer-reviewed. Cuba developed its own vaccine, a point of pride for Cubans, due to harsh sanctions still imposed by the U.S., an antiquated holdover from the first Cold War.

Cuba, which is averaging roughly 8,000 new covid-19 cases every day, reported 3,727 new covid-19 cases in children on Monday and Tuesday alone, according to the Miami Herald, including 236 infants and 16 newborns.

Getting children vaccinated will be vital to stopping the global pandemic, largely because kids now make up an increasingly large share of the cases. There were at least 243,000 cases of covid-19 in children from Sept 2. to Sept. 9 in the U.S., according to the American Academy of Pediatrics, representing roughly 29% of all cases in the country. Compared to the percentage of cases in children since the start of the pandemic last year, 15%, the virus is clearly making its way through unvaccinated children at an alarming speed.

Sri Lanka surpassed WHO vaccination goals.

Sri Lanka surpassed WHO vaccination goals, with 50% of population fully vaccinated.

Sri Lanka reached an important milestone yesterday (September 18) with 50% of the population fully vaccinated, surpassing vaccination goals set by the World Health Organization (WHO).

Vaccinate, vaccinate, vaccinate has been the chant for the pandemic response.  This is based on the science of vaccines and global evidence that COVID-19 vaccines can protect against severe disease as well as limit the transmission of the virus, the WHO says.

WHO has called for all countries to vaccinate 10% of their population by the end of September and 40% by the end of the year.  

Issuing a press release, WHO says that President Gotabaya Rajapaksa’s ‘ambitious vaccination effort’ that spearheads Sri Lanka’s COVID-19 response has long surpassed WHO’s targets.  It is also likely to surpass its own target of vaccinating 60% of the population by 31 December, the WHO predicts.

Sri Lanka has used six vaccines – AstraZeneca (Japan), Covishield, Moderna, Pfizer, Sinopharm, and Sputnik.  All except Sputnik have WHO Emergency Use License (EUL).  So far, Sri Lanka has received 27 million vaccine doses, of which 12.2% were accessed through COVAX AMC.

Sri Lanka-born researcher appointed to U.S. National Cancer Advisory Board.

A leading Johns Hopkins cancer researcher Dr. Ashani Weeraratna, who is of Sri Lankan origin, has been appointed by U.S. President Joe Biden to serve as a member of the National Cancer Advisory Board.

The White House announced the appointment on Wednesday (15th).

Dr. Weeraeatna, who specializes in melanoma and the effects of aging on cancer, is the E.V. McCollum Chair of Biochemistry and Molecular Biology at the Johns Hopkins Bloomberg School of Public Health and a Bloomberg Distinguished Professor.

She also serves as the co-leader of the Cancer Invasion and Metastasis Program at the Sidney Kimmel Comprehensive Cancer Center at Johns Hopkins, and a professor of oncology at the Johns Hopkins University School of Medicine. She had joined the Johns Hopkins faculty in 2019.

According to John Hopkins University statement, Dr. Weeraratna’s research focuses on the effects of the tumor microenvironment—the normal cells and structures surrounding a tumor—on metastasis and therapy resistance.

She is one of the first researchers to study how the aging microenvironment influences metastasis and therapy resistance in melanoma.

Her studies encompass biophysical changes that affect the ability of both tumor and immune cells to migrate through tissues. Her research has found age-related differences in responses to both targeted therapy and immunotherapy, findings that may one day inform clinical practice.

Born in Sri Lanka and raised in Lesotho in Africa, Dr. Weeraratna first came to the United States in 1988 to study biology at St. Mary’s College of Maryland. She earned a Ph.D. in Molecular and Cellular Oncology at the Department of Pharmacology of George Washington University Medical Center.

She is President of the Society for Melanoma Research, and a fierce champion of and a mentor for junior faculty, people of color and women in science, technology, engineering, and math (STEM).

Britain begins world's largest trial of blood test.

Britain's state-run National Health Service will on Monday begin the world's biggest trial of Grail Inc's (GRAL.O) flagship Galleri blood test that can be used to detect more than 50 types of cancer before symptoms appear.

The Galleri test looks at the DNA in a patient's blood to determine if any come from cancer cells. Earlier diagnosis of cancers leads to dramatically increased survival rates.

The NHS said it wanted to recruit 140,000 volunteers in England to see how well the test worked as part of a randomised control trial. Half of the participants will have their blood sample screened with the Galleri test right away.

U.S. will authorize Pfizer COVID-19 vaccines for kids age 5-11 in October.

Top US health officials believe that Pfizer Inc's Covid-19 vaccine could be authorised for children aged 5-11 years old by the end of October, two sources familiar with the situation said on Friday 10 September 2021.

The timeline is based on the expectation that Pfizer, which developed the shot with Germany's BioNTech, will have enough data from clinical trials to seek emergency use authorisation (EUA) for that age group from the US Food and Drug Administration (FDA) towards the end of this month, the sources said.

They anticipate the FDA could make a decision on whether the shot is safe and effective in younger children within three weeks of the EUA submission.

The decision on whether to authorise a vaccine for younger children is eagerly anticipated by millions of Americans, particularly parents whose children started school in recent weeks amid a wave of infections driven by the Delta variant.

COVID-19 pandemic increasing risk factors for suicide.

COVID-19 pandemic is triggering an increase in risk factors for suicide, and suicide prevention “must be prioritized” after 18 months into the pandemic that brought social isolation among the population, America’s office of the World Health Organization (WHO) warned ahead of World Suicide Prevention Day.

Novel COVID-19 has exacerbated risk factors associated with suicidal behaviours, such as job loss, trauma or abuse, mental health disorders and barriers to accessing health care, the global health agency warned. Furthermore, it added that globally, one in 100 deaths is reported by suicide, making it among the leading causes of death worldwide and the fourth leading cause of death among 15- to 29-year-olds.
