KARACHI, Jul 6 2023 – The first thing you notice about eight-month-old Manahil Zeeshan is how tiny she looks on the adult-size hospital bed at the government-run Sindh Institute of Child Health and Neonatology (SICHN) in Korangi, a neighbourhood in Karachi.

Her right foot is taped with a cannula, and she whimpers incessantly. “I have been in and out of the hospital for the last seven days,” said Uzma Mohammad, Zeeshan’s mom, with worry lines on her forehead. “High fever that refused to come down, severe cough for days and breathlessness,” were some of the symptoms Mohammad described. She was convinced someone had “put a spell” on her daughter.

The doctors, however, suspected she had typhoid.

Salmonella Typhi bacteria cause typhoid fever, and Salmonella Paratyphi bacteria cause paratyphoid fever. According to the US-based public health agency, Centers for Disease Control and Prevention, along with a fever that can be as high as 103 to 104°F (39 to 40°C), the sick person can have weakness, stomach pain, headache, diarrhoea or constipation, cough, and loss of appetite. Some people have a rash of flat, rose-coloured spots.  Internal bleeding and death can occur but are rare. It affects between 11 and 20 million people each year, leading to 128,000 to 161,000 deaths, according to the World Health Organization (WHO). The highest fatality rates are reported in children under four years of age.

While Zeeshan’s blood culture report had yet to come to ascertain the cause of her sickness, she needed urgent medical care, said Dr Shabita Bai, who had admitted her.

“We could not wait for five days for the blood culture report as she was not doing well. And because she had already been given an antibiotic (a medicine used to kill bacteria) from outside, our chances of finding if the baby had typhoid for sure were slim, and we had to rely on the history,” justified Bai.

Decisions had to be made. Based on her condition, symptoms, and clinical diagnosis, the baby was given Ceftriaxone, an intravenous antibiotic, but she showed no improvement. The doctors then administered the stronger Meropeneme intravenously, a last-resort antibiotic.

Battling the Superbug

But even if she had typhoid, the bacteria in her body had taken on the form of a superbug — the extensively drug-resistant (XDR) typhoid and the current antimicrobials had become ineffective, said paediatrician Dr Jamal Raza, the executive director of the SICHN.

According to a Lancet study published in 2022, multidrug-resistant (MDR) typhoid has been seen in Pakistan, while typhoid bacteria resistant to the widely-used antibiotic azithromycin have been found in Bangladesh, Nepal and India. “Our analysis revealed a declining trend of MDR typhoid in south Asia, except for Pakistan, where XDR S Typhi emerged in 2016 and rapidly replaced less-resistant strains,” stated the study, which researchers claim is the largest ever examination of the S.Typhi bacterium.

The reason why antibiotics are losing their punch against some types of bacteria, said Raza, was the “indiscriminate use of antibiotics” that health practitioners prescribe to provide immediate relief. Another big problem was self-medication by people. “I know people often use an old prescription by a doctor to get the same medicine if they feel they have the same symptoms, thinking they do not need to visit the doctor.”

But he pointed out viruses, which are also small germs like bacteria, are causing bacteria-like infections, like a cold or the flu.

“Taking an antibiotic for the latter does not treat the disease; it only leads to antibiotic resistance,” said Raza.

A study conducted by researchers from three medical institutions, namely, the Aga Khan University (AKU) in Karachi, the Armed Forces Institute of Pathology (AFIP) in Rawalpindi, and the Shaukat Khanum Memorial Cancer Hospital & Research Center (SKH) in Lahore in 2018, found indiscriminate use of antibiotics to be causing new drug-resistant “superbugs.”

It found a high prevalence of multidrug and fluoroquinolone resistance for both S.Typhi and S. Paratyphi strains of typhoid bacteria. From 20% in 1992, the resistance was found to have increased to around 50% in 2015. The stubborn bacteria were resistant to antibiotics like ampicillin, chloramphenicol (and co-trimoxazole), as well as fluoroquinolone (ciprofloxacin and/or ofloxacin).

“The situation is quite grim,” said Dr Mashal Khan, chairperson of the government-run paediatric medicine department at Karachi’s National Institute of Child Health, referring to the increase in the number of children developing resistance to typhoid drugs. His worry is not that the bacteria has spread; his concern is the bacteria has mutated and become resistant to the drug.

“We’re running out of new antibiotics to treat bacterial infections; Meropeneme is the last one, and a very expensive one too,” he said resignedly, adding: “Although the development of newer antibiotics is the need of the day, I must emphasise the rational use of the ones being used is more urgent.”

Developing new drugs is challenging, and antibiotics more so, as the science is tricky.

“Antibiotics are not the most lucrative drugs to develop for pharmaceuticals as their utility is limited in the future due to the bacteria developing the ability to resist them,” said Infectious Diseases specialist and epidemiologist Dr Faisal Mahmood at the Aga Khan University Hospital in Karachi. “A lot of money goes into developing new drugs, and since most of the funding is from the global north, they prefer to work on infections which concern them directly. Typhoid is unfortunately endemic in the low and middle-income countries in the South, which have poorer water quality and have warmer, more humid climates.”

And that is why the only sure-shot way of reducing the disease burden of typhoid is to vaccinate the children.

In 2019, Pakistan became the first country to get the World Health Organization (WHO)-recommended single-dose typhoid conjugate vaccine (TCV) injected intramuscularly, added to its routine immunisation (RI) regime. This is given to babies at nine months, alongside measles-rubella vaccinations, without impacting either vaccine.

“Childhood vaccination complemented with clean drinking water and improved hygiene practices is the much more cost-effective way of eradicating typhoid than pumping antibiotics in a child,” said Raza. Meropenem costs as much as Rs. 30,000 (USD 105) for a 10-day course, and if hospitalisation is included, it can go up to Rs 100,000 ($349), said the doctor. Being in a government hospital, Zeeshan is treated free of cost.

Typhoid Vaccine Launch Hits a Snag as Covid-19 Surfaces

The 2019 TCV campaign was first launched in the two cities of Sindh – Karachi and Hyderabad (children up to 15 years of age were also given a shot), which reported the highest number of typhoid cases among children. There was a pause when Covid-19 hit the world. But by 2022, TCV had been launched across Pakistan, and 35.5 million children were vaccinated, after which it was added to the government-run Expanded Programme on Immunisation (EPI) programme.

“Many parents do not know that the TCV is a more effective vaccine but only available at government vaccination centres, and not at private clinics and hospitals as Gavi has only given it to the government of Pakistan,” said paediatrician Dr D.S. Akram.

“There is another typhoid vaccine available in the private sector (typhoid polysaccharide vaccine), but it can only be given to children over two years of age, and it needs boosters every three years. My advice to parents is to vaccinate their kids against typhoid bacteria at nine months,” she said.

But it is still a drop in the ocean, and the fight against typhoid and other childhood diseases continues. The WHO places Pakistan among the ten countries that account for almost two-thirds of the world’s unimmunised children.

When Covid-19 hit the country’s already crumbling health system, it also brought the country’s immunisation programme to a halt too. An estimated 1.5 million children across Pakistan missed out on basic vaccines from March to May 2020, according to Gavi.

For Pakistan, which already has low immunisation coverage (the percentage of fully immunised children aged 12-23 months is just 66%), it meant a further dip in coverage which led to an unprecedented rise in the number of zero-dose children (those that have not received any routine vaccine). Add to these were the almost 19,000 new births every day. But when the lockdown eased and vaccinators returned to work, there was less demand for vaccination, having been replaced by fear of the new virus.

While Pakistan has yet to reach the optimal immunisation coverage of 90%, during Covid-19, Pakistan’s EPI received plaudits internationally for taking both vaccine coverage and the number of zero-dose children close to pre-pandemic levels in 2021. “What Pakistan achieved needs to be celebrated. In fact, Pakistan and Chad are used as examples internationally of how to get it right in an emergency,” said Huma Khawar, an immunisation and child health advocate working closely with EPI.

“Despite a year’s delay due to Covid-19, which was unforeseen, I think it is the best thing that the government has done for its country’s children,” said Khawar. She credited the RI programme that bounced back to the pre-pandemic level in 2021.

Clean water, Good Hygiene Key to Preventing typhoid

While immunisation can protect children from getting infected, clean drinking water and improved hygiene practices can reduce the risk of catching the disease to a great extent.

“Vaccines provide immunity when there is exposure to the bacteria,” agreed Dr Jai Das, assistant director at the Institute for Global Health and Development at the Aga Khan University and one of the co-authors of the 2018 report on typhoid, but emphasised the need for improved water and sanitation, a situation that continues to remain dismal and compromised in Pakistan.

The same study not only found a strong correlation between water and sanitation but to literacy levels as well. In addition, it stressed improving the country’s food safety protocols and implementing regulations.

While Mohammad believes that her daughter is under a curse, one reason could be that the unpasteurised cow’s milk she gives her daughter may not be properly boiled at home. “I was unable to breastfeed her,” she said. Further, she confessed to diluting it with unboiled tap water to make it last longer.

Doctors say giving Pakistani babies a lease of life is simple and costs nothing. “Exclusive breastfeeding up to at least six months of age (right now it is only 43%), attaining 90% coverage of RI across Pakistan and improving water and sanitation quality,” according to Dr Akram.

Bacteria Don’t Respect Geographic Borders

The XDR typhoid bacteria propagating in Pakistan has crossed borders and reached as far as the UK, Canada and the US. Earlier this year, a team of Pakistani and US researchers published their findings in the American Journal of Tropical Medicine and Hygiene, stating that with numerous typhoid bacteria variants circulating in Pakistan have also been identified in Southeast Asia and Eastern and Southern Africa and have been introduced into the United Kingdom, Canada, and the United States by travellers.

The Lancet study said strains from South Asia had spread 200 times to other countries since 1990. When these superbugs grow and spread, they can cause infections that are hard to treat. Sometimes they can even spread the resistance to other bacteria they meet.

The future looks frightening. While the need for improving water and sanitation cannot be overemphasised, along with the need for vaccinating children, newer and stronger antibiotics need to be developed and fast as typhoid may surface in deadlier ways than now since very few antibiotics remain effective against the bacteria.

The Grand Narrative of Private Finance: Over-Reliance on Attracting Investment is Undermining Change at World Bank

By Bhumika Muchhala and María José Romero
NEW YORK / BRUSSELS, Jul 6 2023 – One message that was repeated throughout last month’s summit on a so-called “New Global Financing Pact” was that developing countries urgently need mass financing to tackle the climate and biodiversity emergency. And there is not enough of it in public coffers.

Unfortunately, the false narrative that the only way to fill this gap is to ‘leverage’ more private finance also persisted. The resulting Paris Agenda for People and Planet stated: “meeting global challenges will depend on the scaling up of private capital flows.” This should be achieved in large part by revamping the role of multilateral development banks (MDBs).

Last December, the World Bank Group (WBG), the biggest MDB, launched its so-called “evolution” process, with the support of G7 governments. This set the institution to work on increasing its lending by deepening its reliance on the financial market.

The dogged reliance on private capital as saviour appears to be steeped in capitalist realism. It is believed to be implausible for the public sector to deliver the scale of financing needed to address the climate and development crisis.

Private capital, which can be leveraged using public money, securitised and reproduced is favoured as the pragmatic choice. However, while the financing gap to deliver on the sustainable development goals is very real, the neat narrative buttressing private capital obscures two empirical realities.

First is the absence of rich countries’ political will to deliver on agreed commitments, from the 0.7 per cent of Gross National Income in development aid made in 1970 to the US$100 billion per year climate financing agreed in 2009.

Second, the ongoing systemic wealth drain from developing to rich countries. Since 1982, developing countries as a whole have transferred an estimated US$4.2 trillion in interest payments to global north-based creditors, far outstripping aid flows and concessional lending during the same period.

Additionally, tax-related illicit financial flows cost countries hundreds of billions of dollars in lost tax income every year. Debt servicing is draining approximately 25 per cent of total government spending in developing countries as a whole, hijacking both climate and SDG (Sustainable Development Goals) financing.

The allure of private finance

Last month, in a new attempt to ‘leverage’ private capital, the WBG launched the Private Sector Investment Lab, a partnership with the private sector that aims to “rapidly scale solutions that address the barriers preventing private sector investment.”

Furthermore, it announced “an expanded toolkit for crisis preparedness, response, and recovery” that includes providing “new types of insurance” to backstop private sector projects. This follows a not-so-new pattern articulated in the WBG’s Evolution Roadmap draft published in April

While the WBG is set to expand its mandate to incorporate “sustainability” considerations, the approach is still rooted in a heady cocktail of de-risking instruments such as risk guarantees, blended finance and first-loss positions by governments, and in tweaking national regulatory frameworks to enable a business-friendly environment.

The goal is as singular as the solution: to make investment more profitable for the private sector. The (optimistic) rationale: ‘incentivising’ private capital will ‘crowd in’ economic growth and climate, biodiversity and development financing. This assumes that it is possible to equate commercial goals and the public interest, which is not always the case without creating financial barriers that undermine access to public services, such as user fees.

It also ignores that risks are transferred from private to public actors, further increasing debt vulnerabilities, and the developmental dilemma posed by prioritising private profits over distributive goals and state sovereignty.

In ongoing discussions about the Roadmap, it is yet to be seen if the WBG will incorporate sufficient provisions within its plans to ensure the recipient state’s right to regulate in the public interest for a rights-based economy that upholds distributive justice. That is, economic, climate and gender equity.

Solutions with legitimacy

The largest coalition of developing countries in the United Nations (known as the “Group of 77”), representing 134 nations, have been calling for reform of the international tax, debt and financial architecture for many years.

These calls, enshrined in resolutions adopted by the UN General Assembly, includes establishing a multilateral legal framework that would comprehensively address unsustainable and illegitimate debt, including through extensive debt restructuring and cancellation, and agreeing on a UN Tax Convention with equitable participation of developing countries to address tax abuse by multinational corporations and other illicit financial flows.

As was made clear last month in several developing countries’ calls, a reform agenda should not be limited to merely boosting MDBs’ coffers – via financial innovation techniques – but rather include governance reform that meaningfully augments the voice and vote of developing countries in macroeconomic decision-making, which is the litmus test for legitimate and democratic economic governance.

Furthermore, for many in civil society, for the WBG to “evolve” in a credible way it must also seek to independently evaluate the development impact of its policy prescriptions for developing countries over recent decades. Civil society organisations are stating this again in official feedback on the Evolution Roadmap submitted to the Bank this week.

The ways in which the mythology of the private financier is construed dangerously omits the concrete reforms for historical economic justice, and state sovereignty, that the global south are demanding. This disjuncture calls for a clear-eyed questioning of the allure of private finance. Here lies the difference between new forms of extraction as opposed to change towards redistributive justice.
