Battling Insects, Parasites and Politics

By DONALD G. McNEIL Jr.

OMJI, Nigeria - The reason for all the excitement, one public health doctor after another trooping into her mud-walled room to have a look, was that Patience Solomon had correctly hung her new royal blue mosquito net over the bed she shared with her 2-year-old son, James.

Mosquito nets are not terribly complicated, as long as you have something to suspend them from - in Mrs. Solomon's case, a hand-hewn rafter just at head-knocking height beneath her corrugated iron roof.

Permeating the nets with insecticide does take a little concentration.

A state health worker had just given a demonstration beneath the village's central baobab tree: take half a Coke bottle full of water and a big enamel bowl, mix in the sachet of white powder, dunk the net, and let dry. Remember to rinse out the bowl before making food in it. (If you forget, it's not a disaster; the lambdacyhalotrin is more lethal to bugs than to children.)

Mosquito nets are technically very simple but in their own mundane way, in rural Africa, they are highly political objects.

Somji, a hot, dry collection of mud compounds in the sorghum and millet fields of Nigeria's central plateau, is one of the special weapons and tactics laboratories in the global struggle over mosquito net policy - a "piggybacking village."

"This is the first place in the history of the country where we're combining the distribution of bed nets with the distribution of drugs," said Dr. Emmanuel Miri, chief of Nigerian operations for the Carter Center in Atlanta.

The drugs are for lymphatic filariasis, a disease caused by eight-inch worms that ball up and nest in the lymph glands, clogging them until victims' legs swell to the thickness of an elephant's. There is no cure for the leg, nor do the worms die, but, given once a year to everyone in the village, the drugs Mectizan and Albendazole, donated by Merck and GlaxoSmithKline, kill the worms' microscopic progeny as they circulate in the blood.

Unable to reproduce, the infestation dies out when the adult worms shrivel up of old age, in about five years. But there is an exception: the drugs cannot be given to children under 5 or to pregnant women.

Normally, they go unprotected, hoping to shelter under the umbrella of "herd immunity" created when the rest of the village is de-wormed. (When herd immunity works, the uninfected have benefited from a combination of preventive medicine and dumb luck.)

But pregnant women and children under 5 are also the most likely to die of malaria. And malaria, like lymphatic filariasis, is spread by mosquitoes.

James had already had malaria once, Mrs. Solomon said.

Asked what she gave him for it, she produced a bottle whose label she could not read. It turned out to be a local brand of Tylenol, meaning that James had already had a serious stroke of luck with one fatal disease.

The Carter Center, a health and peace organization founded by former President Jimmy Carter, has been handing out de-worming drugs in Nigeria since the 1980's. It has no budget for mosquito nets. But Roll Back Malaria, a World Health Organization campaign started in 1998, does, has some money because malaria is relatively "hot" at the moment, thanks to the Global Fund to Fight AIDS, Tuberculosis and Malaria. So in Somji, the two programs are piggybacking, meaning everyone in each family should get either Carter drugs or a W.H.O. net.

But that requires juggling layers of bureaucracy, since the W.H.O. sends its donation through the Nigerian federal government, which filters the nets down to state governments, which send out workers to do demonstrations. In the two central states where the program is centered, Niger and Plateau, three million people get the drugs. The two states received only 60,000 nets. (Nigeria has more than 100 million people, and no national program.)

What will happen when those run out?

"That is why we are begging you people to come to our aid," said Rachel Titi Bitrus, the net-dunking Health Ministry demonstrator. "We pray maybe we will get some more."

Equally good nets are sold at roadside markets, but they are several hours away on foot and cost from $6.50 to $14, she said, adding, "Many complain that that is too dear."

Big donors and their consultants are deeply divided on whether mosquito nets, like condoms, should be distributed by "social marketing" in which donated goods are not distributed free, but advertised as rival brands with catchy names and sold for nominal sums.

Some economists argue that poor Africans value and use only things they have paid for. Others retort that such schemes benefit only the "richest of the poor," like city dwellers who can afford cigarettes, while the poorest poor - peasant farmers in dirt-track villages like Somji, who bear the greatest burden of mosquito diseases - die for lack of items the West can mass-produce for pennies.

Officials from the United States Agency for International Development favor social marketing of nets; those from the Centers for Disease Control and Prevention oppose it. Unicef favors it; W.H.O. opposes it.

And even if the macroeconomic disputes are resolved, there are micro problems. Somji is a two-hour drive from the regional capital, Jos, but Mrs. Bitrus has only occasional use of a truck. The Carter Center program relies on a network of volunteers from thousands of tiny villages, the kinds of places where ownership of a bicycle or a radio puts the owner in an upper-income bracket.

"The same guy who used to ride his bike to pick up a box of meds now has to somehow pick up a ton of bed nets," said Dr. Frank O. Richards Jr., a parasitologist at the C.D.C. who advises the Carter Center. "They've got to figure that out. "

Dr. Richards was watching the volunteers juggle the new complexities. With pigs rooting at their feet, they stood outside a compound, called out each resident by name, and spooned out pills.

One 5-year-old gagged on his fat Albendazole tablet. "Let him chew it! Tell him he can chew it!" Dr. Richards shouted, trying to get his words translated from English to Hausa to the village language.

"What about the baby?" he asked aloud, when the volunteers had dosed a nursing mother and said they were finished. "He's supposed to get a net," he muttered. "This is the crucial thing. They didn't even think about babies before."

The volunteers explained that they wanted to do that later in the day. Their data-recording system consisted of two lined primary school notebooks, one for pills and one for nets, and doing both at once would sow confusion.

Hence the eventual excitement about Mrs. Solomon. The successful hoisting of her net - made in Kenya, paid for in Geneva, arranged for in Atlanta, demonstrated in Somji - was no simple matter.

The next move, Dr. Richards said, would be a surprise visit in a few weeks. Now that nets had value, he said, "we'll want to see if the right people are using them - or if all the fathers are sleeping under them."

As the team climbed into its trucks to leave, a loud argument broke out. A visitor from another village was shouting at a Carter Center volunteer, accusing him of handing out nets free here while dignitaries were watching, but charging his village 80 cents each. Dr. Miri stepped out of his truck, questioned the volunteer, fired him on the spot and asked the village chief to pick another.

The team left; the politics went on.

An Indian perspective

Malaria claims 9 in Jhargram (West Bengal)

Statesman News Service
MIDNAPORE, March 21. The outbreak of malaria in Jhargram subdivision, particularly in Belpahari, Binpur, Lalgar, Jamboni and Jhargram block, in Midnapore West, has claimed the lives of nine persons over the past three weeks. Although locals suspect that the deceased may have contracted the malignant variety of the disease, health officials have remained tight-lipped over the issue as they are still awaiting the blood reports. Most of the deceased and the affected come from the Sabar, Lodha and Adivasi communities who sleep in the open.
The deceased include Baiydayanath Hansda (28), Biswanath Baske (42), Kusum Mahapatra (40), Sundari Hansda (34), Nareswar Mahato (26), Gokul Majhi (50), Sada Bhakta (32), Ritu Mallik (36) and his seven-year-old son Bhim. Of the affected, 30 are recuperating in Jhargram Sub-Divisional Hospital.
Most of the affected have complained of symptoms such as shivering, high fever, headaches which are consistent with malaria.
Jharkhand Party (Naren) president Mrs Chuni Bala Hansda alleged that no anti-mosquito drive had been undertaken in this sub-division despite the fact that Belpahari and Binpur are highly malaria-prone and six persons had succumbed to the disease last year.
A BSF jawan deployed in Belpahari to deal with the Maoists had succumbed to the disease earlier. But even then the district authorities had refused to act, Mrs Hansda said. She also alleged that the district administration was trying to prove that the deaths were not caused by malaria and had occurred owing to delay in taking the deceased to hospital. District officials, however, blamed the lack of awareness among villagers for the deaths and pointed out that they had ignored the instructions issued at the health camps organised at regular intervals in the area.
