Brazilian researchers on discovery of COVID-19 virus in November sewage
A Brazilian research team found samples of the new coronavirus in the sewer system of the southern city of Florianopolis back in late November 2019, three months before the first COVID-19 case was officially recorded in the country on February 26.
The researchers from the Applied Virology Lab at the Federal University of Santa Catarina (UFSC) published their findings in a paper on June 26. CGTN’s correspondent in Brazil, Paulo Cabral, has spoken to two leading researchers on the team for more details about their discovery.
“We are sure of what we found in the November sample. It is the SARS-CoV-2 virus. We have no doubts about that,” Patricia Stoco, a geneticist at the lab, told CGTN.
“We are now effectively working on sequencing the whole genome of these samples, so we’ll be able to compare the sequencing of the virus found in our samples from late November with that of the virus now actually circulating and infecting people,” she said.
“Doing that we could maybe detect mutations that could possibly explain the increase in the number of cases now,” she added, stressing that comparing the full genetic sequencing is important to deepen understanding about the virus.
Gislaine Fongaro, a virologist at the university, explained how the research was conducted. She said the samples were collected from raw sewage in the pipes en route to the treatment plant.
“These samples were collected monthly between October 2019 and March 2020. So we take the samples to the laboratory and freeze them. That’s why we could go back over them now – they were frozen,” she said.
“Results came back negative for SARS-CoV-2 in the samples from October. And then negative again in the early November samples. But then results came back positive for the first time for a sample from November 27. And then all samples tested came back positive until March 2020,” she explained.
She said it’s possible that if they went further back, they could find more positive results for the novel coronavirus.
“It would be very important if we could review samples dating back to the beginning of the year [of 2019],” she said, adding that she hopes their research will encourage other teams who may have access to older samples to check them, and also encourage researchers to look into other older clinical samples taken from patients, which could also help tell the story of the virus.
“Because if we found this in the sewer, that’s because people were already carrying the virus. That means there were already people who were infected but were not diagnosed because we did not know about the virus back then,” she noted.

Financing Health Futures: Nigeria, Ghana, Uganda Turn to Tobacco and Telecom Taxes in Big Push Against Malaria
African leaders, parliamentarians, health experts, and development partners have renewed their commitment to ending malaria by 2030, with a bold call for domestic financing through innovative taxation on tobacco, alcohol, and telecom services to close critical funding gaps.
The discussions took center stage at the Big Push Against Malaria: Harnessing Africa’s Role high-level political engagement in Abuja, where Nigeria, Ghana, and Uganda showcased new homegrown financing strategies aimed at reducing dependence on dwindling donor support.
Africa’s Heavy Burden
Malaria remains one of Africa’s deadliest diseases. In 2023, the world recorded 263 million cases and nearly 600,000 deaths, with 94% of cases and 95% of deaths occurring in Africa. Nigeria alone accounted for 26.6% of global cases and 31% of deaths, according to the World Malaria Report 2024. Children under five remain the most vulnerable, making up 76% of deaths.
Despite progress — with Nigeria cutting malaria deaths by more than half since 2000 through insecticide-treated nets, preventive treatments, and the rollout of the new R21 malaria vaccine — leaders warned that global targets are off-track. The World Health Organization’s technical strategy for malaria (2016–2030) has stalled since 2017, with Africa unlikely to meet its 2025 and 2030 milestones without urgent action.
Taxing for Health Futures
The Nigerian Parliament’s Committee on HIV/AIDS, Tuberculosis, and Malaria (ATM) announced plans to fund malaria elimination through “sin taxes” and telecom levies.
According to the House Chair on ATM, Hon. Linda Ogar, a bill is underway to restructure the National Agency for the Control of AIDS (NACA) into a multi-disease agency that will address HIV, TB, and malaria.
The new financing mechanism proposes:
Taxes on tobacco, alcohol, and other luxury items
Dedicated levies on telecom airtime and mobile money transactions
A percentage of the nation’s consolidated revenue
“These resources will provide sustainable funding to strengthen health systems and accelerate malaria elimination,” Ogar said, stressing that Africa must stop relying solely on foreign donors. “We cannot continue to take two steps forward and five steps backward. Africa must begin to show the world that we are ready to solve our problems ourselves.”
Similar models are already being piloted in Ghana and Uganda, where levies on mobile money and telecoms are being redirected to finance health interventions. The Abuja meeting urged other African countries to adopt this approach as part of a continental framework for sustainable financing.
Leaders Call for Urgent Action
Nigeria’s Minister of State for Health and Social Welfare, Dr. Iziaq Adekunle Salako, emphasized that while malaria is preventable and treatable, it still kills hundreds of thousands yearly due to funding shortfalls, climate change, insecticide resistance, and humanitarian crises.
“To truly defeat this disease, we must rethink, join forces, and mount a concerted ‘Big Push’. Funding gaps remain a major obstacle, and innovative domestic financing is the way forward,” Salako declared.
From the civil society front, grassroots representatives pledged to act as “foot soldiers”, demanding that communities have a seat at the decision-making table. The World Health Organization, Bill & Melinda Gates Foundation, Aliko Dangote Foundation, and other partners reaffirmed support but stressed the need for stronger political will and local ownership.
Private Sector and Global Support
Representing billionaire philanthropist Aliko Dangote, the Nigeria Malaria Council reiterated that private sector investment must complement government financing. Meanwhile, the Global Fund confirmed it has invested nearly $2 billion in Nigeria’s malaria response and committed an additional $500 million for 2024–2026, including support for local production of malaria drugs.
The Gates Foundation’s Uche Anaowu noted that while progress has slowed, malaria remains beatable:
“Smallpox is the only human disease ever eradicated. The question is — can malaria be next? I believe Africa has both the burden and the opportunity to lead the world in making that happen.”

The Big Push: From Talk to Action
Speakers acknowledged that Africa has hosted too many malaria meetings without concrete outcomes. This time, however, leaders insisted the Abuja gathering must mark a turning point — from dependency to self-reliance.
With Nigeria, Ghana, and Uganda setting the pace on tax-based health financing, the continent now faces the challenge of replicating and scaling up these models.
“Now that Africa is at a critical point, the need for a Big Push against malaria cannot be overemphasized. If we align political will, innovative financing, and community engagement, we can end malaria within our lifetime.”
Nigeria, Ghana, and Uganda are pioneering a shift from donor dependence to domestic revenue mobilization via tobacco, alcohol, and telecom taxes — a model hailed as central to financing Africa’s health futures and ending malaria by 2030
