Tremendous progress has been made in efforts to wipe out polio around the world. Before a global eradication program began 30 years ago, about 350,000 children became paralyzed from polio each year. The figure dropped to 28 in 2018.

Nevertheless, Helen Rees, chair of the World Health Organization’s emergency committee, said Friday that polio remained an international threat. She said every available health strategy must be used to prevent the wild polio virus from spreading across borders.

“The fear is that we might well see a resurgence, that we could see exportation again and a reversal of all of the work and all of the country global efforts that have gone into trying to eradicate polio,” Rees said. “And we certainly cannot allow that to happen.”

Polio remains endemic in Afghanistan, Pakistan and Nigeria. Rees said that over the last few months, there has been a worrying exportation of the wild polio virus to and from Pakistan and Afghanistan.

“We have got widespread, positive environmental sampling in Pakistan,” she said. “And in Afghanistan, because of the more difficult situation there in terms of security, we are unable to access probably as many as a million children for vaccination.”

Separately, there is good news from the African region. The director of WHO’s polio eradication program, Michel Zaffran, noted that the wild polio virus has not been seen in Nigeria since it was last detected more than two years ago.

If this keeps up, he said, the regional certification commission could be able to declare the wild polio virus eradicated from the African region at the end of 2019 or early 2020. He said $4.2 billion would be needed over the next five years to see the last of this disease.

Polio, which has no cure, invades the nervous system and can cause irreversible paralysis within hours. The WHO says polio is transmitted from one person to another through the fecal-oral route, or less frequently by a common vehicle like contaminated food and water. Fever, fatigue, headache, vomiting, stiffness in the neck and limb pain are among polio’s symptoms. (VOA)

As Climate Talks Come to a Halt, Africa Suffers From Global Warming

The World Health Organization warns that climate change will exacerbate the impact of some disease and health problems.

Efforts to boost global action against climate change are stuttering, as several key nations have objected to a key United Nations-backed report on the impacts of rising temperatures at the COP24 talks in Poland.

Many developing nations say they are already suffering from the impact of climate change, especially in south Asia and Africa, where water shortages and intense storms are putting lives and livelihoods in danger.

In Malawi in southern Africa, a bustling fish market stood at Kachulu on the shores of Lake Chilwa just five months ago. Now, hundreds of fishing boats lie marooned across the vast bay as vultures circle over the cracked, sun-baked mud. Water levels here fluctuate annually, but scientists say climate change is making the seasonal dry-out of the lake far more dramatic. Fishermen are being forced to leave and look for work elsewhere, says Sosten Chiotha, of the non-governmental organization ‘LEAD’ – Leadership for Environment and Development.

“Climate change contributes to the current recessions that we are experiencing, because you can see that in 2012 there was a recession where the lake lost about 80 percent of its water. Then it recovered in 2013, but not fully. So since then every year we have been experiencing these recessions,” Chiotha said.

Scientists gathering at the COP24 climate talks say it is developing countries like Malawi that are being hit hardest by the impacts of climate change.

The charity Water Aid has released a report ranking the countries worst-hit by water shortages, with Sudan, Niger and Pakistan making up the top three.

“There are people who are living with the impact of climate change right now. And they’re feeling those impacts not through carbon, but through water. And as we’ve seen over the past few years and will continue to see for many years to come unfortunately, is a huge increase in water stress and absolute water scarcity,” Water Aid’s Jonathan Farr told VOA from the climate talks currently underway in the Polish city of Katowice.

Richer nations have pledged $100 billion a year for poorer nations to deal with the consequences of climate change. Water Aid says they are failing to deliver the money.

Scientists say emissions of carbon dioxide would have to be reduced by 45 percent by 2030 to have any hope of keeping global warming below 1.5 degrees Celsius – the target agreed in the Paris climate deal.

However, the number of coal-fired power stations – the most polluting for

m of energy generation – is growing. The German organization ‘Urgewald’ calculates that $478 billion had been invested into expansion of the coal industry between January 2016 and September 2018.

There is little optimism at the talks that much concrete progress will be made, as several countries including the United States, Russia and Saudi Arabia have already voiced objections to a key scientific report from the U.N.’s Intergovernmental Panel on Climate Change. (VOA)
