A billion people in 43 countries are at risk of cholera, the United Nations warned Friday, and though the outbreaks could be stopped, the United Nations said resources were desperately lacking.

Providing simple and cheap healthcare measures to pregnant women -- such as offering aspirin -- could prevent more than a million babies from being stillborn or dying as newborns in developing countries every year, new research said on Tuesday.

Top U.N. officials, health industry leaders and activists have demanded that the world invest more to develop new vaccines and tackle a surge in tuberculosis fueled by the impact of COVID-19 and conflicts including Ukraine and Sudan.

At a crowded meeting punctuated by activists chanting "End TB Now," there were speeches from many TB sufferers and a keynote by U.N. Deputy Secretary-General Amina Mohammed, who spoke about how her father passed on tuberculosis to her two-year-old sister: TB claimed his life at the age of 60, but her sister, now 50, is a survivor.

The World Health Organization said Friday that COVID-19 no longer qualifies as a global emergency, marking a symbolic end to the devastating coronavirus pandemic that triggered once-unthinkable lockdowns, upended economies worldwide and killed at least 7 million people worldwide.

WHO said that even though the emergency phase was over, the pandemic hasn't come to an end, noting recent spikes in cases in Southeast Asia and the Middle East. The U.N. health agency says that thousands of people are still dying from the virus every week.

The World Health Organization's emergency committee is meeting Thursday to discuss if Covid-19 is still a global health emergency.

The panel's 15th meeting on the crisis comes more than three years after it first sounded the WHO's highest emergency alarm as what was then called the novel coronavirus began spreading outside China.

Paramedics summoned to an Arizona retirement community last summer found an 80-year-old woman slumped inside her mobile home, enveloped in the suffocating 99-degree (37 C) heat she suffered for days after her air conditioner broke down. Efforts to revive her failed, and her death was ruled environmental heat exposure aggravated by heart disease and diabetes.

In America's hottest big metro, older people like the Sun Lakes mobile home resident accounted for most of the 77 people who died last summer in broiling heat inside their homes, almost all without air conditioning. Now, the heat dangers long known in greater Phoenix are becoming familiar nationwide as global warming creates new challenges to protect the aged.

Widespread loneliness in the U.S. poses health risks as deadly as smoking a dozen cigarettes daily, costing the health industry billions of dollars annually, the U.S. surgeon general said Tuesday in declaring the latest public health epidemic.

About half of U.S. adults say they've experienced loneliness, Dr. Vivek Murthy said in a report from his office.

Nearly 13 million children missed one or more vaccinations in Africa between 2019 and 2021 because of the disruptive impact of the COVID-19 pandemic, leaving the continent vulnerable to even more outbreaks of disease and facing a "child survival crisis," a new report from UNICEF said Thursday.

Amid a global "backslide" in childhood immunization over those three years, which the United Nations Children's Fund said is the worst regression for childhood vaccinations in 30 years, Africa is the region with the highest number of unvaccinated and under-vaccinated children. UNICEF said that 12.7 million African children missed one or more vaccinations and 8.7 million didn't receive a single dose of any vaccine from 2019-2021.

When China suddenly scrapped onerous zero-COVID measures in December, the country wasn't ready for a massive onslaught of cases. Hospitals turned away ambulances, crematoriums burned bodies around the clock, and relatives hauled dead loved ones to warehouses for lack of storage space.

Chinese state media claimed the decision to open up was based on "scientific analysis and shrewd calculation," and "by no means impulsive." But in reality, China's ruling Communist Party ignored repeated efforts by top medical experts to kickstart exit plans until it was too late, The Associated Press found.

Genetic material collected at a Chinese market near where the first human cases of COVID-19 were identified show raccoon dog DNA comingled with the virus, adding evidence to the theory that the virus originated from animals, not from a lab, international experts say.

"These data do not provide a definitive answer to how the pandemic began, but every piece of data is important to moving us closer to that answer," World Health Organization Director-General Tedros Adhanom Ghebreyesus said Friday.
