US CDC Sees No Major Shift in COVID Variants 

Currently spreading COVID-19 variants such as EG.5, or Eris, do not represent a major shift in COVID variants, and updated vaccines in September will offer protection, the director of the U.S. Centers for Disease Control and Prevention said Wednesday. 

“Right now, what we’re seeing with the changes in the viruses, they’re still susceptible to our vaccine, they’re still susceptible to our medicines, they’re still picked up by the tests,” Dr. Mandy Cohen said in an interview on former Biden administration adviser Andy Slavitt’s “In the Bubble” podcast. “We’re seeing small changes that are what I would call subtypes of what we’ve seen before.” 

Updated vaccines should be available by mid- to late September, she said. 

COVID-19 vaccine manufacturers have created new versions of their vaccine, which were updated to target the so-called XBB.1.5 subvariant that was dominant earlier this year, in order to more closely resemble the circulating virus.  

“We anticipate that they are going to be available for most folks by the third or fourth week of September,” Cohen said. The vaccines still need to be authorized by the U.S. Food and Drug Administration, and the CDC needs to make its recommendations, she said.  

“We are likely to see this as a recommendation as an annual COVID shot just like we have an annual flu shot,” she said. 

Pfizer, Moderna and Novavax have all said they expect to have supplies of the updated vaccine ready for the rollout this autumn. 

On Wednesday, the World Health Organization classified the EG.5 coronavirus strain, circulating in the United States and China, as a “variant of interest” but said it did not seem to pose more of a threat to public health than other variants. Eris is the fasting-growing COVID-19 subvariant in the U.S., estimated to be responsible for around 17% of current COVID cases, according to the CDC.

US Launches Contest to Use AI to Prevent Government System Hacks

The White House on Wednesday said it had launched a multimillion-dollar cyber contest to spur use of artificial intelligence to find and fix security flaws in U.S. government infrastructure, in the face of growing use of the technology by hackers for malicious purposes.  

“Cybersecurity is a race between offense and defense,” said Anne Neuberger, the U.S. government’s deputy national security adviser for cyber and emerging technology.

“We know malicious actors are already using AI to accelerate identifying vulnerabilities or build malicious software,” she added in a statement to Reuters.

Numerous U.S. organizations, from health care groups to manufacturing firms and government institutions, have been the target of hacking in recent years, and officials have warned of future threats, especially from foreign adversaries.  

Neuberger’s comments about AI echo those Canada’s cybersecurity chief Samy Khoury made last month. He said his agency had seen AI being used for everything from creating phishing emails and writing malicious computer code to spreading disinformation.

The two-year contest includes around $20 million in rewards and will be led by the Defense Advanced Research Projects Agency, the U.S. government body in charge of creating technologies for national security, the White House said.

Google, Anthropic, Microsoft, and OpenAI — the U.S. technology firms at the forefront of the AI revolution — will make their systems available for the challenge, the government said.

The contest signals official attempts to tackle an emerging threat that experts are still trying to fully grasp. In the past year, U.S. firms have launched a range of generative AI tools such as ChatGPT that allow users to create convincing videos, images, texts, and computer code. Chinese companies have launched similar models to catch up.

Experts say such tools could make it far easier to, for instance, conduct mass hacking campaigns or create fake profiles on social media to spread false information and propaganda.  

“Our goal with the DARPA AI challenge is to catalyze a larger community of cyber defenders who use the participating AI models to race faster – using generative AI to bolster our cyber defenses,” Neuberger said.

The Open Source Security Foundation (OpenSSF), a U.S. group of experts trying to improve open source software security, will be in charge of ensuring the “winning software code is put to use right away,” the U.S. government said.

US to Restrict High-Tech Investment in China

U.S. President Joe Biden is planning Wednesday to impose restrictions on U.S. investments in some high-tech industries in China.

Biden’s expected executive order could again heighten tensions between the U.S., the world’s biggest economy, and No. 2 China after a period in which leaders of the two countries have held several discussions aimed at airing their differences and seeking common ground.

The new restrictions would limit U.S. investments in such high-tech sectors in China as quantum computing, artificial intelligence and advanced semi-conductors, but apparently not in the broader Chinese economy, which recently has been struggling to advance.

In a trip to China in July, Treasury Secretary Janet Yellen told Chinese Premier Li Qiang, “The United States will, in certain circumstances, need to pursue targeted actions to protect its national security. And we may disagree in these instances.”

Trying to protect its own security interests in the Indo-Pacific region and across the globe, National Security Adviser Jake Sullivan said in April that the U.S. has implemented “carefully tailored restrictions on the most advanced semiconductor technology exports” to China.

“Those restrictions are premised on straightforward national security concerns,” he said. “Key allies and partners have followed suit, consistent with their own security concerns.”

Sullivan said they are not, as Beijing has claimed, a ‘technology blockade.’”

Indonesia’s Capital Named World’s Most Polluted City

Indonesia’s capital Jakarta topped the list as the world’s most polluted city on Wednesday, having consistently ranked among the 10 most polluted cities globally since May, according to data by Swiss air quality technology company IQAir.  

Jakarta, which has a population of over 10 million, registers unhealthy air pollution levels nearly every day, according to IQAir.  

Resident Rizky Putra lamented that the worsening air quality was putting his children’s health at risk.  

“I think the situation is very worrying,” Rizky, 35, told Reuters TV by the side of a road in downtown Jakarta.  

“So many children are sick with the same complaints and symptoms such as coughs and cold,” he said.  

Jakarta residents have long complained of toxic air from chronic traffic, industrial smoke and coal-fired power plants. Some of them launched and won a civil lawsuit in 2021 demanding the government take action to control air pollution.  

The court at the time ruled President Joko Widodo must establish national air quality standards to protect human health, and the health minister and Jakarta governor must devise strategies to control air pollution.  

Still, Nathan Roestandy, co-founder of air quality app Nafas Indonesia, said the pollution level has continued to deteriorate.  

“We take more than 20,000 breaths a day. If we take in polluted air everyday, (it could lead to) respiratory and pulmonary diseases, even asthma. It can affect cognitive development of children or even mental health,” he said.  

Asked about Jakarta’s pollution problem on Tuesday, President Widodo told reporters the solution would be to move the country’s capital city from Jakarta to Nusantara, which his government is currently building from the ground up on Borneo island.  

Indonesia is set to name Nusantara as the new capital next year and at least 16,000 civil servants, military and police are due to move there.

Health Conditions Deteriorate as More People Flee Sudan  

U.N. agencies warn health conditions are deteriorating in Sudan and neighboring countries as growing numbers of people flee escalating fighting between the Sudanese Armed Forces and paramilitary Rapid Support Forces.

Before the conflict erupted on April 15, 4.5 million Sudanese already were displaced — more than 3.7 million inside Sudan and another 800,000 as refugees in Chad, South Sudan, Egypt and Ethiopia.

Since the rival generals went to war, the U.N. refugee agency says nearly an equal number — more than four million people — have become newly displaced.

“The situation inside Sudan, where UNHCR teams are present, is untenable as needs far outweigh what is humanly possible to deliver with available resources,” said William Spindler, UNHCR spokesman.

He said a lack of medicine and a shortage of staff to care for the sick and wounded in White Nile State severely hampered health and nutrition services in all 10 refugee camps, “where over 144,000 newly displaced refugees from Khartoum have arrived since the conflict started.”

He said many families that have been on the move for weeks, with very little food and medicine, were arriving at border entry points and transit centers in neighboring countries in desperate condition.

As a result, he said malnutrition rates have been rising, as have disease outbreaks and related deaths.

“Between 15 May and 17 July, over 300 deaths, mainly among children under five years, were reported due to measles and malnutrition,” he said.

“In addition, severe cholera and malaria cases are expected in the coming months due to flooding from the continuing rains and inadequate sanitation facilities.”

Now in its fourth month of conflict, the World Health Organization says insecurity, as well as limited access to medicine, medical supplies, electricity and water pose a challenge to the delivery of health care.

WHO spokesman Christian Lindmeier said attacks on health facilities were increasing, preventing the sick and wounded from accessing medical treatment. He said the WHO has verified 53 attacks on health care, causing 11 deaths and 38 injuries, between April 15 and July 31.

“Attacks on health care are a gross violation of international humanitarian law and the right to health. They must stop. Humanitarian workers need assurances of safety and security in order to continue delivering critical humanitarian and health response,” he said.

Meanwhile, the U.N. Food and Agriculture Organization warns Sudan is facing a deepening food crisis, noting that “20.3 million individuals in Sudan face severe hunger, a figure that has nearly doubled since last year.”

Maximo Torero, FAO chief economist, said a recent U.N. food assessment shows “the level of acute food insecurity in Sudan has increased substantially to more than 11 million people because of the conflict. So, the situation is deteriorating.”

Meanwhile, in a bit of welcome news, the U.N. Office of the Coordination of Humanitarian Affairs, OCHA, confirmed Tuesday that the first humanitarian convoy since the start of the conflict had arrived in the East Darfur state after nine days on the road and that “those supplies have been distributed to more than 15,000 people in remote villages in the state.”

Additionally, OCHA said that the FAO had provided 430 tons of agricultural seeds “to be distributed to farmers across the state by the Ministry of Agriculture.”

U.N. agencies agree that the competing generals’ power grab has deepened Sudan’s humanitarian crisis. They warn the lives of many people are hanging by a thread, lives that will be lost without more donor support.

The Federal Ministry of Health says 12,200 people have been injured and 1,205 killed since April 15, figures U.N. agencies believe are greatly underestimated.

Australian Study Warns of Air Conditioning Health Fears 

Darwin, the capital city of Australia’s Northern Territory, can be brutally hot and humid.   Many of its 150,000 residents seek refuge from the tropical elements in air-conditioned homes, offices and cars.

But research from the Australian National University, the ANU, suggests that air-conditioning, which is often set at 21 degrees Celsius, is making people more vulnerable to heat-related death.

Heatwaves are Australia’s deadliest natural hazard.  They kill more people than bushfires, floods and storms put together.

The ANU asserts that “climate change is increasing heat-associated mortality particularly in hotter parts of the world.” 

Simon Quilty, the study’s lead author, is from the Australian National University’s National Centre for Epidemiology and Population Health. He told VOA that avoiding the heat and humidity may prevent people from adapting to the climate.

“Being exposed regularly to the prevailing climate in which you live actually acclimatizes your body,” he said. “e know that acclimatization takes roughly 14-days to occur for a human body and that changes the way that we sweat, it changes the way that we breathe, it changes our kidneys and it even changes the way that our hearts pump.  What is happening now is that our entire lives are set at 21 degrees Celsius and so for people who are living in very hot climates like the Northern Territory that deacclimatization is actually probably increasing heat vulnerability.”

Quilty said the research also finds that First Nations communities in the Northern Territory are less vulnerable to heat because they are often less inclined or able to use air-conditioning.

“Yes, it is very, very uncomfortable in really hot weather in Darwin and other places in the Tropics around the world, but we do not all need to live at 21 degrees Celsius,” Quilty said.  “And certainly, my experience of Aboriginal people is they really do not like over air-conditioned environments.  They feel very uncomfortable in it.”       

Quilty says that First Nations people have shown “extraordinary resilience to extreme weather” over thousands of years.

The Australian National University study believes that “hot climate communities need to start considering socio-cultural means of adapting to hotter weather.”  

Indigenous Australians invariably stay out of the hot afternoon sun and reduce physical exertion in warmer parts of the day.  The study recommends that housing in hot climates should also be designed to ensure passive cooling to reduce energy costs.

The Australian research also asserts that a siesta – or an afternoon nap – during the warmest part of the day can help the body to acclimatize to the heat.    

The study is published in the journal, the Lancet Planetary Health.
