A step closer to an age without malaria

Update: March, 06/2016 - 16:45


Bringing in help: Quảng Bình Province reported more than 500 malaria cases and no deaths in 2015. Most of the cases are located in border communes, where people move across the border in Tuyên Hóa and Minh Hóa to trade. In order to prevent and cure malaria cases, medical workers are based at border points and remote villages, where medical aid takes longer to get through.

Every year at this time, Tạ Thị Tĩnh packs her bags to take the 1,000-km train and then a bus to Bình Phước Province which is one of the few provinces in the whole country still grappling with malaria.

Working for the last 36 years at the National Institute of Malariology, Parasitology and Entomology (NIMPE) in Hà Nội, Tĩnh says every year she makes these trips to the malaria-infested hotspots to gather samples and conduct studies about the parasites that cause malaria in humans.

In 2011, Deputy Prime Minister Nguyễn Thiện Nhân signed The National Strategy for Malaria Prevention, Fighting and Elimination from 2011 to 2020 with a vision until 2030. This Masterplan mobilised all relevant administrative and medical authorities to provide the population with preventive methods to reduce malaria cases in the country, provide medication for confirmed cases, aiming at completely eliminating the disease by 2030.

Now, just five years after the Masterplan became effective, the results have been quite impressive and that has prompted some medical researchers to believe that the country can reach its malaria elimination goal as projected.

The authorities of Ministry of Health, Việt Nam and WHO malaria experts and of course, provincial authorities met in Hà Nội at a conference held on March 3 to review achievements in 2015 and work out the next five-year plan for 2016-2020.

World Health Organisation representative  Gawrie N.L. Galappaththy, a medical officer on malaria and other vectorborne and parasitic diseases, spoke to Việt Nam News about the 40-percent reduction of malaria cases from 2014 to 2015.

“This is a remarkable achievement, when you compare it with greater Mekong sub-region countries,” she said. “I can attribute this success to good programme management and effective use of existing interventions and tools for malaria control.”

This year marks the 25th anniversary since the largest outbreak of malaria in 1991, when more than a million confirmed cases were reported and nearly 5,000 people died of the disease.

In 1999, there was also another malaria outbreak in Gia Lai Province.

Tĩnh recalls, "What I remember most is this boy, about 7, who was seriously ill." The boy's father was one of the local authorities, but he would not allow doctors to take his son out of the village for tests and treatment.

According to the local custom, if the son died outside of the village, his parents would be punished with a buffalo or a cow.

"When we got there," Tĩnh continues, "the boy had already gone into coma and ants had already gathered on his eyes. However, the parents insisted on only praying and keeping him home."

"We spent a long time convincing the father, who finally allowed us to take his son to the community clinic. After testing positive, we gave him medicine, it was artesunate, another anal artemisinin-based medication, after which we rushed him to the provincial hospital," she said.
"We came back four days later to see him sitting up!"

Limited budget

In an interview with Việt Nam News, director of the National Institute of Malariology, Parasitology and Entomology, Trần Thanh Dương said that the national budget for malaria was limited to meet the actual demand. This budget allocation, approved for a five-year duration, meets less than half of the demand.

"We have mobilised assistance for malaria control from international organisations, notably from the Global Fund. Every year, the committed budget for malaria accounts for more than 50 per cent of the overall expense. In particular, in 2014, this number went to more than 80 per cent."

Well into the third month of 2016, the annual budget has been earmarked to stay the same as the year before, which is VNĐ60 billion (US$2.7) million. But this allocation has not been approved up until the time of the interview taken on March 2, 2016.
"We do not know how much we will allocate for 2016," Head of the Preventive Medicine Department, Trần Đắc Phu told Việt Nam News on telephone.

The total funds mobilised from international resources have been estimated at more than VNĐ240 billion ($10 million) this year, according to institute Director Dương.

A veteran malaria researcher, who declined to be named, said that since the 1990s, when the annual budget stayed modest, the government of Việt Nam spared a lot of financial resources to fight malaria.

In the past 10 years, thanks to the emphasis of the Government and the Ministry of Health, the national malaria programme has received a priority status. The budget allocated for malaria-related programme rose from VNĐ65 billion ($4 million) in 2006, when $1 was equivalent to VNĐ16,100 to VNĐ105 billion ($5 million) in 2011 when the rate went up to VNĐ21,000 for one US dollar.

However since then, due to the economic crises, the national budget went down steadily, and was especially low in 2014, when it dropped by 40 per cent from the previous year.

Also, according to this Masterplan, a total amount of VNĐ1,673 billion ($79,7 million) has been committed to fight and eliminate malaria by 2030.

Ambitious goals

Despite the limited amount of the government budget for fighting malaria, Việt Nam as a country has accomplished remarkable results in lowering malaria cases as well as the mortality rate.

As outlined in the government-approved masterplan, Việt Nam is committed to keep the confirmed cases under 0.15 per 1,000 people, the number of mortalities at 0.02 per 100,000 people. This number means it tries to keep the malaria cases at 15 for every 100,000 people and 2 deaths for ten million people.

It also planned to bring 40 provinces into the prevention mode, 15 provinces on the malaria eliminating mode, and eight provinces to pre-elimination mode by the year 2020.

According to the World Health Organisation (WHO) World Malaria Report 2015, which provided the statistics, in 2014, Việt Nam reported more than 15,000 cases, and six deaths, lower than 2013.

In 2015, the number of malaria cases dropped to 9,000 and only three deaths for over 90-million population, according to NIMPE latest report.

The confirmed cases meant a blood test seen through a microscope that can detect parasites that cause malaria.
 

Self-reliance

"In the 1970s, we were at the institute when we heard that China had found a cure for malaria from the extract of a plant named thanh hao hoa vàng," Tĩnh of the National Institute recalls. "But we had no clue and we had no programme or received any aid/support from China."

"After national reunification in 1975, we set out to look for this plant," she says. "Our detection of the region where this plant could be growing was incorrect. So we went south to look for it. But we could not find it."

She said that the search took a few years and they had to wait for the end of the Border War in 1979 with China to go north and look for it.

The team included Dr. Trương Văn Như, Trịnh Ngọc Hải and another herbal expert from the Traditional Medicine Plant Department under MoH.

"We finally found the medicinal plant in Lạng Sơn, (where heavy fighting took place in 1979). When we found it, we only used it as a medicinal concoction by simmering it in water for long hours, the traditional way of extracting oriental herbal medicine. We used the concoction to treat domestic cattle with immune disease with good results."

Tĩnh went on to say that the institute then was working on a project to manufacture locally-made medication. The first pills made of artemisinin powder were produced in 1989 at the Việt Nam's National Academy of Sciences.

The thanh hao hoa vàng, or better known in English as the Sweet sagewort or sweet wormwood can grow higher than 1 metre in height. It produces beautiful yellow blooms with a soft fragrance.

This plant, known in ancient Chinese medicine as qing-hao, provides natural arteminisinin that can help reduce fever.

According to reports in the Quy Nhơn Institute of Malariology, Parasitology and Entomology, back in the 14th century, Tuệ Tĩnh, Việt Nam’s founding father of traditional medicine, had already used extracts from thanh hao hoa vàng to cure fever.

Western-trained doctors, however, tread another path in treating patients. Some said they did not know about the treatment in medicinal history.

Today, Vietnamese companies produce artemisinin-based medication to provide a cure for patients.

"The standard dose lasts for three days. It takes effect very quickly and gets out of the body also quickly. In general it is very safe to use," Tĩnh from the Hà Nội Institute says.

But director Dương has warned against the steady decrease of national funding as the fight is not yet over.

"A decrease in government funding for the national malaria fighting programme will result in a rise in confirmed cases, deaths or disease outbreak," he says.

He then cites five reasons for this warning.

“First of all,” he says, "we have recorded parasites that are resistant to the current medication we use in five provinces, and it is in danger of spreading out across the country."

Secondly, he says that mosquitoes have become resistant to the chemicals that are used to kill them and as a result have lowered the prevention methods.

He further said that uncontrolled immigration for economic reasons from malaria-free regions to malaria-stricken areas will increase cases.

He also added that the habit of not using mosquito nets in thatched huts when tending to crops in the forests will expose people to infection.

A WHO representative at the conference reiterated the concerns raised by NIMPE.

“Still we have some problems: drug resistance , migrant mobility  and of course, funding issues,” the representative said. Geographically, Việt Nam belongs to Southeast Asia. But WHO lists Việt Nam in the Western Pacific Region in its malaria report.
Dương's warning is ever more relevant because just last week, The Lancet warned of a malaria outbreak from the Western Pacific Region that can spread to India, the gateway to Africa, where the most people die of the disease.

"We strongly call the Government of Viet Nam to maintain the national budget to fight malaria," he says.

"The importance of keeping the budget strong for the 2016 to 2020 period will put Việt Nam on the sustainable path to continue reducing the positive cases and meet the national target of completely eliminating the disease in 2030.

Only if no more positive cases are reported for three continuous years, can the country be declared malaria-free, according to WHO standards.

At the above-mentioned conference, , Director of the Quy Nhơn Institute Dr. Nguyễn Văn Chương, announced some bad news.

“There were two malaria-related deaths in Phú Yên Province in the two first months before this meeting,” he said. “However, one case was still disputable. We, however, need to stay alert despite the good results last year.”
