WHO says COVID-19 origins remain inconclusive due to lack of data
GENEVA — A World Health Organization (WHO) expert group tasked with investigating the origins of the COVID-19 pandemic has released its final report, concluding that the origins of the virus remain inconclusive despite more than three years of scientific work.
The group, chaired by Marietjie Venter, stated that most available data still points to a natural spillover of the virus from animals to humans, echoing conclusions from the WHO's earlier 2021 mission that suggested transmission from bats to humans via another animal host.
However, the group said it was unable to access sufficient data from China to fully assess the possibility of a lab-related incident.
'Despite repeated requests, key genetic sequences and biosecurity details were not provided by Chinese authorities,' Venter said at a press briefing.
'Therefore, the hypothesis of a laboratory accident could neither be confirmed nor excluded. It remains speculative and unsupported by scientific evidence.'
The group also found no indication that the virus had been circulating outside of China before December 2019, and there was no evidence that SARS-CoV-2 was deliberately manipulated in a lab.
The report, which comes after years of geopolitical tension over the origins of the virus, highlighted internal disagreements within the expert group.
One member resigned prior to publication and three others requested their names be removed from the final document.
WHO Director-General Dr. Tedros Adhanom Ghebreyesus reiterated that understanding the origins of the pandemic is a 'moral imperative,' citing the more than 20 million lives lost, the trillions of dollars in economic disruption, and the global upheaval caused by COVID-19.
The findings also reflect longstanding challenges in international scientific cooperation. An earlier investigation by the Associated Press revealed that China halted key efforts to trace the virus' origin in early 2020, and that the WHO missed early chances to launch a comprehensive probe.
While U.S. officials, including President Donald Trump, have long promoted the lab-leak theory, a 2021 U.S. intelligence review concluded there was not enough evidence to support or dismiss it.
Chinese officials continue to reject the notion of a lab origin and argue that origin-tracing efforts should be expanded to other countries.
Scientists involved in the WHO-led investigation have also identified a list of animals that could have served as intermediate hosts, including raccoon dogs, civet cats, and bamboo rats. — Agencies

France Bans Smoking in Beaches, in Parks and Bus Shelters
France will ban smoking on beaches and in parks, public gardens and bus shelters from Sunday, the government said. The decree, published in the official government gazette Saturday, will also ban smoking outside libraries, swimming pools and schools, and is aimed at protecting children from passive smoking. Health and family minister Catherine Vautrin said in May that tobacco must disappear where there are children. The freedom to smoke "stops where children's right to breathe clean air starts", she said. Offenders face a fine of up to €135 ($154), Vautrin added. The ban will not extend to France's iconic cafe terraces however, the minister said. Electronic cigarettes, which have boomed in France in recent years, are also not covered. An estimated 35 percent of France's population are smokers – higher than the averages for Europe (25 percent) and the world (21 percent), according to the World Health Organization. Around 75,000 people are estimated to die from tobacco-related complications each year in France.

WHO delivers its first medical aid to Gaza since March 2
The World Health Organization said Thursday that it had delivered its first medical shipment into Gaza since March 2, adding though that the nine truckloads were 'a drop in the ocean.' Wednesday's shipment of supplies, plasma and blood will be distributed among hospitals in the Palestinian territory in the coming days, WHO chief Tedros Adhanom Ghebreyesus said on X. Israel imposed a total blockade on the Gaza Strip on March 2. More than two months later, it began allowing some food in, but no other aid items until now. Tedros said nine trucks carrying essential medical supplies, 2,000 units of blood and 1,500 units of plasma were delivered via the Kerem Shalom crossing with Israel, 'without any looting incident, despite the high-risk conditions along the route.' 'These supplies will be distributed to priority hospitals in the coming days,' Tedros said. 'The blood and plasma were delivered to Nasser Medical Complex's cold storage facility for onward distribution to hospitals facing critical shortages, amid a growing influx of injuries, many linked to incidents at food distribution sites.' Last week the WHO said only 17 of Gaza's 36 hospitals were minimally to partially functional, with the rest unable to function at all. Tedros said four WHO trucks were still at Kerem Shalom and more were on their way towards Gaza. 'However, these medical supplies are only a drop in the ocean. Aid at scale is essential to save lives,' he said. 'WHO calls for the immediate, unimpeded and sustained delivery of health aid into Gaza through all possible routes.' Israel began allowing supplies to trickle in at the end of May following its more than two-month total blockade, but distribution has been marred by chaotic scenes and near-daily reports of Israeli forces firing on people waiting to collect rations. The Gaza Humanitarian Foundation, a new US- and Israel-backed food distribution system, began handing out food in Gaza on May 26. But the UN and major aid groups have refused to cooperate with the GHF – an officially private effort with opaque funding – over concerns it was designed to cater to Israeli military objectives. Israel is pressing its bombardment of the territory in a military offensive it says is aimed at defeating the militant group Hamas, whose unprecedented October 2023 attack on Israel triggered the war.
