Snakebites: The hidden health crisis that kills 200 people a day

"Every 5 minutes, 50 people are bitten by a snake"

(CNN)Snakebites kill more than 200 people a day around the world, but Thai firefighter Pinyo Pookpinyo was one of the lucky ones.

When the tip of his thumb was bitten by a king cobra, he made it to a Bangkok hospital within 15 minutes. There, he was given a serum that stopped the venom, which can be fatal, from attacking his nervous system.

"The doctor didn't believe at first that I was bitten by a king cobra. I had to tell him that I was an instructor teaching about snakes; I'm very good at identifying types.

"It affected me for about two months. I had to go back to the hospital to undergo surgery for another two times to remove dead tissues from my thumb."

But most victims of snakebites don't live so close to a hospital, nor do they have Pookpinyo's professional knowledge of snakes. For them, a misplaced step or being in the wrong place at the wrong time can be fatal.

Snakebites kill between 81,000 and 138,000 people and disable 400,000 more every year. It's a problem that is exacerbated by a global shortage of snake anti-venom, especially in rural areas of sub-Saharan Africa and Asia where appropriate health-care facilities are few and far between.

According to the UK's Wellcome Trust, a research charity, snakebites cause more death and disability than any other neglected tropical disease.

"Snakebite is -- or should be -- a treatable condition. With access to the right anti-venom, there is a high chance of survival," said Professor Mike Turner, Wellcome's director of science.

"While people will always be bitten by venomous snakes, there is no reason so many should die."

It's an assessment that the World Health Organization agrees with. On Thursday, the global health body is launching a strategy to deal with the problem, which campaigners describe as the world's biggest hidden health crisis.

It aims to halve death and disability from snakebites by 2030 by investing $136 million in educating communities to prevent bites, making more effective treatments and improving health-care systems.

The Wellcome Trust is also behind the push, investing £80 million ($101.3 million) over the next seven years. It's a dramatic change of fortune for the field, as only £30 million ($38 million) was invested in the previous decade, according to Wellcome.

Antiquated treatments
Scientists say new approaches are needed to produce anti-venom that's safer, cheaper and more effective.

The current method has changed little since the 19th century: Venom is extracted from a snake and administered to a horse or other animal in small doses to evoke an immune response. The animal's blood is drawn and purified to obtain antibodies that act against the venom.

"It comes from a horse, and injecting horse proteins into people isn't without its risks. There is relatively high rates of adverse reactions," whether mild, like rash and itch, or more serious, like anaphylaxis, said Phil Price, Wellcome's snakebites science lead.

"Anti-venoms are far from perfect. A lot aren't clinically tested in the same way other drugs are tested."
It is also work that hasn't been profitable for pharmaceutical companies. In 2010, Sanofi Pasteur halted production of its FAV-Afrique anti-venom, effective for several African snakes.

One avenue of research that scientists at Wellcome plan to pursue with the new funding is a universal anti-venom. They'll also look at alternatives to anti-venom as well as making existing development methods more rigorous.

The snakes regarded as the biggest killers of people include the saw-scaled viper found in Africa, the Middle East, India and Pakistan and the Russell's viper, found in India and southeast Asia, said Price.

Global shortage
According to Wellcome, the world has less than half of the anti-venom it needs. And the anti-venom that is available in some places can often be ineffective because it isn't adapted to local species; anti-venoms have been developed for only about 60% of the world's venomous snakes.

This problem is particularly acute in Africa, where up to 90% of anti-venom is thought to be ineffective. This can make people distrustful, so they turn to local healers instead of hospitals.

And when it is available, it can also be prohibitively expensive, plunging poor victims into deeper straits. On average, one vial of anti-venom costs $160, and a full course usually requires multiple vials, Wellcome says.
One 2013 study from India found that more than 40% of victims had to take out a loan to pay for treatment, and in order to repay it, families often had to sell valuables.

"If you are spending your income to pay for treatment, transportation and rehabilitation, then something has to go. It's schoolbooks for children or either the food for family," said Dr. Bernadette Abela-Ridder of the WHO Department for the Control of Neglected Tropical Diseases.

In addition to making better anti-venoms, WHO plans to focus on strengthening health-care systems, prevention and education, making sure people can recognize the poisonous snakes in their communities and making simple changes in behavior such as wearing shoes.

India snakes kill 46,000 a year

Lack of anti-venom in rural areas and difficulty accessing health centres are among a number of factor contributing to 46,000 deaths every year.

NEW DELHI // Chirag Roy set off for the nearby Indian village of Kollara after receiving a call that fateful morning.
A spectacled cobra had been spotted in the neighbouring village, one kilometre away. Would he be able to come immediately?

As the resident naturalist at Svasara Resorts, in the Tadoba Tiger Reserve in eastern Maharashtra, Roy had wanted to rescue the snake. But that morning on March 1, he was bitten by the cobra and died on the way to hospital.

“The villagers had a tendency to kill any snake they saw,” said Ratika Sinha, Svasara’s executive director, adding that Roy often received such phone calls. “He was a very passionate herpetologist, and he tried to rescue the snakes instead.”

Roughly 46,000 people die of snakebites in India every year, according to the American Society of Tropical Medicine and Hygiene, accounting for nearly half of the 100,000 annual snakebite deaths the world over.

If too far off topic please delete mods.

Do you forum members kill snakes you find? I'm a believer most everything here has a good purpose to be here (I am doubtful on tax examiners though) so hate to kill animals I find. I've relocated snakes from our property but couldn't, safely, manage a pit viper I found so dispatched him. I actually hated to do it but was more concerned about the wife and dogs (well OK the mother in law too).

[HHTel]

I usually hook it and sling it over to a neighbour.

If we can get to the snakes before our dogs, we will relocate them, otherwise.......................................

I've relocated a couple of sleepy pit vipers, but if they're well awake then I've had to call the Hua Hin Sawang guys. They couldn't catch one once (incompetence, but no more so than me) so killed it. Other snakes we get are usually kukris or golden tree snakes which aren't dangerous and not too difficult to catch and they go over the garden wall.

[Gregjam]

The golden tree snakes are relocated. I was out when a pit viper hid amongst the water bottles outside the front of our house and by the time I got home it had been killed. If it is a threat to the dogs it’s chances of survival are slim, even slimmer if it is just the Thais around. I get very frustrated with the wife as she hates snakes but will put food out for their prey and does not realise nor will listen to me when I tell her she is attracting snakes.
