NKONDEDZI, Mozambique — Rogerio Bernardo slung a black satchel over his  shoulder and waited by the roadside in the morning mist for a bush taxi.  In dusty wingtips, frayed pants and a gray pinstripe suit coat so big  it swallowed his slender frame, he looked like any peasant farmer  dressed up for a trip to town.        
In fact, Mr. Bernardo, who has 
AIDS,  is in the vanguard of a promising new effort to reverse one of the most  worrisome trends in treating the disease: the growing number of  patients across Africa who fail to collect their lifesaving  antiretroviral medicines.   
The simple solution devised by Dr. Tom Decroo, a Belgian physician  working here in Tete Province for the aid group Doctors Without Borders,  was to organize patients into groups of six. They would then take turns  making the monthly trip to pick up refills, cutting the number of times  each had to go to town — to just two a year, from 12.        
A two-year test of his brainstorm here in Tete, comparing about 300 of  these groups with patients who continued going alone, found that almost  none of those in the groups stopped taking their medicines and only 2  percent died, according to results published in The 
Journal of Acquired Immune Deficiency Syndromes. By contrast, 20 percent of the other patients quit treatment or died.        
“No one abandons treatment in the group,” said Inocencio Alface, a  talkative, slightly built farmer who has become Nkondedzi’s champion for  people with AIDS and leads one of the village’s four patient groups.  “We give each other courage.”        
On a recent morning, it was Mr. Bernardo’s turn to go to town. Before he  joined the group, if he was short of cash for taxi fare he needed to  hike four hours through the bush to the district hospital in Zobue.         
But as his group huddled against the chill, each member contributed 15  meticais, or about 50 cents, for taxi fare. They also counted out their  leftover pills and noted the tally on their medical cards, so a  clinician could tell whether they had taken the previous month’s pills.  Mr. Bernardo tucked the cards into his satchel.        
As he watched the express taxi go by, waiting for a slower one to save  35 cents on the fare, village life floated past him through the mist —  women balancing buckets on their heads, men on bicycles with jangling  bells, schoolchildren carrying stalks of sugar cane as long as fishing  poles.        
When the bush taxi finally arrived at 7:50 — it was just a pickup truck  loaded with people and bags of charcoal — Mr. Bernardo clambered in for  the 18-mile ride.        
The study of this new approach also found that it profoundly lightened  the load on the health professionals who are one of this poor country’s  scarcest resources, sharply reducing their caseloads at public hospitals  and clinics — and, health economists say, trimming the cost of  treatment.        
“We went up there and were blown away,” Dr. Kebba Jobarteh, who heads  the H.I.V. care and treatment program in Mozambique for the United  States Centers for Disease Control and Prevention, said after his visit  to Tete. “We met five groups. They were amazing. This is a potential  game changer for H.I.V.”        
Dr. Decroo acknowledged in an interview that the study design for his  approach did not produce as high a quality of evidence as a randomized  trial would. And Dr. Tim Farley, an AIDS expert with the World Health  Organization who was not involved in the research, cautioned in an  e-mail that because the program was limited to clinically stable  patients, the comparison with other patients might be skewed.        
But Dr. Farley added, “Reducing the health-system burden from these  patients is fantastic and allows the scarce clinical resources to be  used for more complicated patients.”        
The shifting of responsibilities for AIDS treatment from doctors to  nurses to community health workers and even patients has been  necessitated by Africa’s extreme shortage of medical professionals.  Mozambique has only 2.7 doctors per 100,000 people, according to World  Health Organization estimates; the United States has 100 times that.         
When Doctors Without Borders began providing antiretroviral drug  treatment to AIDS patients here in 2003, there were fears that  illiterate rural Africans would not take their medicines properly.  Before the expatriate doctors would even prescribe the complicated  combination therapy, patients were required to show up on time for eight  appointments. For the sickest, poorest patients, the bar was impossibly  high. “Before the eight consultations were done they would die,” Dr.  Decroo recalled.        
The rules for AIDS care have eased greatly since then, but Dr. Decroo  became convinced that they needed to change even more. Though more than  six million people are on antiretrovirals in developing countries, the  United Nations estimates that nine million patients who need them are  not getting them.        
“If you wait to have enough doctors and nurses to treat everyone, how many generations have to die?” he asked.        
Dr. Decroo had his “aha” moment in 2006 while 
reading a paper  co-written by Wim Van Damme, a professor at the Institute of Tropical  Medicine in Belgium, who argued for a radical rethinking of how to  deliver AIDS treatment in poor countries, shifting some tasks to  patients. The professor described how people in rich nations with 
asthma, 
diabetes  and other chronic diseases had become involved in managing their  illnesses, and AIDS patients, too, were a potential resource in Africa,  he wrote. “It was like a thunderbolt from the sky,” Dr. Decroo said. The idea of patient groups leapt into his mind.         
The government of Mozambique has been so encouraged by Dr. Decroo’s  approach that it has decided to test it in every province this year.  “When patients are organized in these small groups, they’re not ashamed  anymore,” said Rosa Marlene, a senior official in the medical assistance  department that oversees AIDS programs. “People start respecting them  because they’re stronger.”        
In Nkondedzi, some groups, including Mr. Bernardo’s, do not hide the  fact that they are H.I.V.-positive, but neither do they flaunt it. They  join for practical reasons: to save money and time.        
But the groups have also brought leaders like Mr. Alface and his wife,  Margarida Isaque, to the fore. At a village meeting, Mr. Alface rose to  speak. “I broke the silence,” he said. “I told them: ‘I’m taking  antiretrovirals. If you see I’m healthy, it’s because of that. All those  who feel in the same situation, come close to me and we will try to  help each other.’ ”        
Many villagers have privately approached him, and about a dozen have  joined groups as a result. But Azesta Vasco came too late. She suspected that her daughter, Cesaltina Pedro, a 27-year-old with two  young daughters, was sick. Ms. Pedro confided to Mr. Alface that she  had AIDS and had quit collecting her medicines because she was too  ashamed to tell her mother she was infected or to ask for money for taxi  fare.         
He got Ms. Pedro to the hospital, but she died a week later. Her two  sad-eyed little girls sat with their grandmother recently in front of  their hut. “She lacked money and encouragement,” Mr. Alface said.         
He and his wife are now trying to fight the stigma that drives people  with AIDS to hide their disease. Ms. Isaque’s nostrils flared angrily as  she described a recent incident when a drunken man, in front of other  villagers, said she had AIDS. Such accusations are against the law in  Mozambique, and she and her husband went to the village court, demanding  justice. The offender was ordered to pay her about $20 and to  apologize.
The village chief, Aviso Supinho, said that Mr. Alface and Ms. Isaque  had raised awareness about AIDS in Nkondedzi and that the groups had  improved villagers’ lives. “If I’m sick and isolated, kept at home, I’m considered a dead body,  though still breathing,” Mr. Supinho said. “But when a person is in a  group, he feels, ‘I’m sick, but I count.’ ”
