Serious questions as PNG malaria infections increase ninefold

MosquitoSTEPHEN HOWES | Australian National University | Edited

CANBERRA - A recent report from the Papua New Guinea Institute of Medical Research shows almost a ninefold increase in the number of cases of malaria in PNG between 2014 and 2017.

The key result of the report is that there has been “an increase in the size of the total population infected with malaria parasites from 50,309 in 2014 to 432,000 in 2017”.

According to the April report, the national prevalence of malaria is now 7.1%. This is up from 5.1% in 2010-11 and a remarkably low 1% in 2014-15.

In many ways, the 7% prevalence underestimates the severity of the problem. The national figure is 10% for children under five. Malaria prevalence among all ages is as high as 16% in Madang, 10.8% in Milne Bay, 8.8% in East Sepik and 8.7% in New Ireland.

For children under five, some of the reported provincial prevalence rates are terrifying: the highest is 20.5% in Sandaun.

What has gone wrong? We know from international research that success in malaria control can be fragile.

In the case of PNG, the report points to three factors: a decline in Global Fund support after 2013; a simultaneous decline in PNG public expenditure in the health sector and the lack of availability of drugs.

It’s pretty simple, although the report also suggests that changes in mosquito biting behaviour (from night to early evening) may have reduced the effectiveness of bed nets.

The earlier drastic reduction in malaria was held up as a PNG success story, as indeed it was.

The reversal raises some very serious questions. These have to be directed first and foremost to the PNG government.

The reduction in health funding and the rise in drug stock-outs is not something that has just happened to PNG because of a fall in resource prices.

By greatly scaling up funds for MPs to spend on various projects, the PNG government has reduced funds for critical expenditures, funds that could have been used for malaria prevention and treatment.

Our own 2017 economic survey showed that health funding increased in the years to 2014, but was sharply cut between 2014 and 2016 - by 37% after inflation.

Those responsible for the corrupt procurement of drugs must also take their share of the blame. The ‘free health’ policy of the last five years has only made things worse.

There are also questions for Australia to answer.

We have set up the Asia Pacific Leaders Malaria Alliance and joined the End Malaria Council. We got PNG, Vanuatu and the Solomon Islands just a few months ago to commit “to the regional goal of ending the disease by 2030.”

But the credibility of Australia’s leadership – not to mention such public statements – is completely undermined if malaria is rampant in our closest neighbour and former colony, and we are unwilling to underwrite the response.

So what exactly is Australia doing to combat malaria in PNG? Where is our leadership?

The DFAT webpage on aid to PNG claims that “our efforts are continuing to make inroads against malaria and tuberculosis”, but in reality the focus is almost entirely on TB. We have only a tiny ($4 million) project with China to improve malaria diagnosis.

The Global Fund website still claims that “PNG has reduced the number of malaria cases and deaths,” which was once true.

The Global Fund continues to support the anti-malaria effort in PNG, albeit at a reduced level. A search of the Global Fund website yielded no documents evaluating its PNG program.

I know, from the experiences of friends and colleagues, that for many of the people of PNG malaria is an ever-present threat, and an all-too-frequent reality.

The resurgence of malaria and the re-emergence of polio are national tragedies. I hope that they serve as wake-up calls for the PNG government and donors alike.

Pleasing it is to see news today and recently, that vaccines or other effective treatments are coming into approval for use against malaria and dengue, and of course, the rollout of vaccine occurring now for Covid-19.

Frightening it is to see reports of the apparent inroads by Covid-19 in PNG, at Western and Enga.

I would hope for a swelling of interest and imperative for Australia to champion and participate to a vastly greater rate in the provision of (and payment for) vaccines to withstand the assault by Covid-19 in the human population of PNG.

What a stopper. People stop Covid or Covid stops people.

Thanks Lindsay. I tweeted on this matter earlier today:

"Malaria kills about 500,000 people each year, half of them children in Africa. A new vaccine, the first to help prevent the disease, will save tens of thousands of lives each year. Unfortunately #PNG will not see it for some time as African kids are the first target."
