GENEVA — Health agencies are urging governments and civil society to step up action to eliminate cervical cancer, a vaccine-preventable disease that kills a woman every two minutes, mostly in low- and middle-income countries.  

“It is the fourth-most common cancer among women worldwide. It is also one of the few types of cancer that can be prevented by a vaccine,” said Herve Verhoosel, spokesperson for Unitaid, an organization that provides affordable lifesaving health products for people in low- and middle-income countries. 

“Vaccination against human papillomavirus, the leading cause of cervical cancer, together with HPV screening and treatment, is a proven path to elimination,” Verhoosel said Tuesday in advance of the first global forum on elimination of cervical cancer. 

The forum, which takes place from March 5 to 7 in Cartagena, Colombia, is hosted by Spain, Colombia and nine leading development and health agencies. 

348,000 women died in 2020

Verhoosel said, “The forum offers a watershed moment for the world to collectively accelerate progress on a groundbreaking promise made in 2020, when nearly 200 countries signed on to the WHO’s global strategy to eliminate cervical cancer.” 

The World Health Organization, Unitaid and other aid agencies provided the statistics on case rates. The WHO estimates 348,000 women died of cervical cancer in 2020, 90% of them from low- and middle-income countries. It warns annual deaths from cervical cancer will likely reach 410,000 by 2030 “if we do not change course.” 

To put countries on the path to elimination, the WHO has set three targets: It calls for 90% of girls to be vaccinated with the HPV vaccine by age 15; 70% of women to be screened with a high-performance test by age 35 and again at 45; and for 90% of women with cervical disease to receive treatment. 

The WHO says sub-Saharan Africa has the highest cervical cancer burden globally. It notes the HIV epidemic has worsened the situation because the common HPV virus is sexually transmitted. 

Prebo Barango, cross-cutting specialist on noncommunicable diseases and special initiatives at the WHO, explains that the prevalence of cervical cancer in some countries “demonstrates the inequity of access to prevention and health care as well as social and economic deprivation” in the affected communities. 

He stressed the importance of vaccinating young girls and making access to screening and early treatment for older women more widely available. 

“It is not an either-or approach,” he said. He notes, however, that “access to screening and treatment has been very, very low because most countries have no coverage for these procedures.” 

Barriers to vaccination

The WHO reports that only one in five adolescent girls has been vaccinated against HPV, despite the vaccine’s proven efficacy. Barango explained that a key constraint related to its use is that the recommended age of 14 for receiving the vaccine “falls outside of the normal vaccination age for children.” 

Besides that, he said, “During COVID-19 there was a significant drop in the uptake of these vaccines because schools were closed” and many health facilities were focused on dealing with the pandemic. 

The World Health Organization says cost effective and evidence-based tools for screening and treatment are available. Despite this, it says barriers and inequities in the hardest-hit areas remain unacceptably high. The WHO notes that fewer than 5% of women in low- and middle-income countries are ever screened for cervical cancer. 

Unitaid spokesperson Verhoosel observed that the WHO’s recommendation of a one-dose HPV vaccine instead of the previous two-dose recommendation could prove to be a game changer. 

“A one-dose HPV vaccine opens new opportunities to reach more girls worldwide and will significantly reduce costs and logistical barriers,” he said. 

The nonprofit GAVI vaccine alliance is providing millions of low-cost HPV vaccine doses to developing countries at the affordable price of around $5.00 per dose. And Unitaid says that, together with its partners, it “has secured agreements that have reduced the price of HPV tests by nearly 40%.”

SYDNEY — Using satellite technology and sophisticated machine learning, a team led by marine experts in Australia have created new maps of the world’s coral reefs.

The scientists discovered there are more coral reefs around the world than previously documented, with Indonesia, Australia and the Philippines having the most coral reefs. 

Over 100 trillion pixels of data were examined. The result is a high-resolution map that gives fresh insight into the distribution of reefs.

The Allen Coral Atlas initiative has identified approximately 348,000 square kilometers of shallow coral reefs globally to depths of up to 30 meters, an increase from previous estimates.

Experts hope the study will allow politicians, scientists and environmentalists to better understand and manage coral reef systems.

Coral reefs face a range of threats, including climate change, overfishing and pollution.

Australia’s Great Barrier Reef — the only living thing visible from space – is also undermined by industrialization and coral-eating crown of thorns starfish.

“In Australia we, kind of, had a reasonable idea of where a lot of our reefs might have been,” Mitchell Lyons from the School of the Environment at Australia’s University of Queensland told the Australian Broadcasting Corp. “But for some jurisdictions across the southwest Pacific or Indonesia, Philippines, there were not very good, consistent maps of where coral reefs were.  I guess the advantage of having these consistent maps all over the globe is that we can start to report and account and, I guess, conserve.”

The maps are publicly available through the Allen Coral Atlas and Google Earth Engine.

The project receives funding from a company founded by the Microsoft co-founder Paul Allen and managed by Arizona State University in partnership with conservationists and the University of Queensland.

The full study was published in the journal Cell Reports Sustainability.  It states that “coral reefs possess a quarter of all marine life and contribute to the well-being and livelihoods of a billion people worldwide.”

Bangkok — Bangkok city employees have been told to work from home to avoid harmful air pollution, as a layer of noxious haze blanketed the Thai capital Thursday.

City authorities asked for cooperation from employers to help workers in the city of some 11 million people avoid the pollution, which is expected to last into Friday.

The air monitoring website IQAir ranked Bangkok among the 10 most polluted cities in the world Thursday morning.

Levels of the most dangerous PM2.5 particles — so tiny they can enter the bloodstream — were more than 15 times the World Health Organization’s annual guideline, according to IQAir.

Bangkok governor Chadchart Sittipunt said late Wednesday that all city employees would work from home Thursday and Friday.

“I would like to ask for cooperation from the BMA network of about 151 companies and organizations, both government offices and the private sector,” he said in a statement, adding that more than 60,000 people were affected.

BMA is an abbreviation for the Bangkok Metropolitan Administration.

Chadchart said at least 20 of Bangkok’s 50 districts were expected to have unhealthy levels of PM2.5 particles, and the problem would linger because of calm weather.

Air quality in Thailand regularly plummets in the early months of the year as smoke from farmers burning stubble in the fields adds to industrial emissions and vehicle exhaust fumes.

Bangkok and the northern city of Chiang Mai ranked among the most polluted cities in the world on a number of days last year.

A public health crisis is brewing over the problem, with at least two million people in Thailand needing medical treatment because of pollution in 2023.

The government of Prime Minister Srettha Thavisin, which took over in August, has promised to make tackling air pollution a “national agenda,” and a draft Clean Air Act was endorsed by his Cabinet last month.

But the problem persists, and a court in Chiang Mai last month ordered the government to come up with an urgent plan to tackle air pollution within 90 days.

CAPE CANAVERAL, Florida — A moon lander built by Houston-based aerospace company Intuitive Machines was launched from Florida early Thursday on a mission to conduct the first U.S. lunar touchdown in more than a half century and the first by a privately owned spacecraft.

The company’s Nova-C lander, dubbed Odysseus, lifted off shortly after 1 a.m. EST (0600 GMT) atop a Falcon 9 rocket flown by Elon Musk’ SpaceX from NASA’s Kennedy Space Center in Cape Canaveral.

A live NASA-SpaceX online video feed showed the two-stage, 25-story rocket roaring off the launch pad and streaking into the dark sky over Florida’s Atlantic coast, trailed by a fiery yellowish plume of exhaust.

The launch, previously set for Wednesday morning, was postponed for 24 hours because of irregular temperatures detected in liquid methane used in the lander’s propulsion system. SpaceX said the issue was later resolved.

Although considered an Intuitive Machines mission, the IM-1 flight is carrying six NASA payloads of instruments designed to gather data about the lunar environment ahead of NASA’s planned return of astronauts to the moon later this decade.

Thursday’s launch came a month after the lunar lander of another private firm, Astrobotic Technology, suffered a propulsion system leak on its way to the moon shortly after being placed in orbit on January 8 by a United Launch Alliance (ULA) Vulcan rocket making its debut flight.

The failure of Astrobotic’s Peregrine lander, which was also flying NASA payloads to the moon, marked the third time a private company had been unable to achieve a “soft landing” on the lunar surface, following ill-fated efforts by companies from Israel and Japan.

Those mishaps illustrated the risks NASA faces in leaning more heavily on the commercial sector than it had in the past to realize its spaceflight goals.

Plans call for Intuitive Machines’ Nova-C vehicle, a hexagonal cylinder with four legs, to reach its destination after about a weeklong flight on February 22 for a landing at crater Malapert A near the moon’s south pole.

If successful, the flight would represent the first controlled descent to the lunar surface by a U.S. spacecraft since the final Apollo crewed moon mission in 1972, and the first by a private company.

The feat also would mark the first journey to the lunar surface under NASA’s Artemis moon program, as the U.S. races to return astronauts to Earth’s natural satellite before China lands its own crewed spacecraft there.

IM-1 is the latest test of NASA’s strategy of paying for the use of spacecraft built and owned by private companies to slash the cost of the Artemis missions, envisioned as precursors to human exploration of Mars.

By contrast, during the Apollo era, NASA bought rockets and other technology from the private sector, but owned and operated them itself.

NASA announced last month that it was delaying its target date for a first crewed Artemis moon landing from 2025 to late 2026, while China has said it was aiming for 2030.

Small landers such as Nova-C are expected to get there first, carrying instruments to closely survey the lunar landscape, its resources and potential hazards. Odysseus will focus on space weather interactions with the moon’s surface, radio astronomy, precision landing technologies and navigation.

Intuitive Machine’s IM-2 mission is scheduled to land at the lunar south pole in 2024, followed by an IM-3 mission later in the year with several small rovers.

Last month, Japan became the fifth country to place a lander on the moon, with its space agency JAXA achieving an unusually precise “pinpoint” touchdown of its SLIM probe last month. Last year, India became the fourth nation to land on the moon, after Russia failed in an attempt the same month.

The United States, the former Soviet Union and China are the only other countries that have carried out successful soft lunar touchdowns. China scored a world first in 2019 by achieving the first landing on the far side of the moon.
