Malaria Site: All About Malaria

Malaria has been haunting mankind since evolution. It has killed more people than all the wars, has greatly influenced our history and geography and has changed many of our genes. During the 3 decades from 1969-2000, hundreds of millions of people were infected with malaria, tens of millions – mostly in sub-Saharan Africa – died, millions of households failed to emerge out of poverty as they struggled with catastrophic health expenditures, hundreds of thousands of pregnant women died during delivery due to malaria-related complications, and millions of children were born with low birthweight, potentially leading to early death or lifelong disability; millions of children who survived struggled with learning as they dealt with frequent absenteeism due to multiple episodes of malaria, chronic anaemia, seizures or cognitive impairment – consequences of infection and severe disease; huge blows were dealt to the growth of already weak post-independence national economies, and their attempts to build viable health systems were hampered by lost productivity and high demand for health care.

In the first 2 decades of the 21st century, claimed to be a golden era in the history of malaria control, unprecedented scale-up of malaria interventions led to considerable reductions in disease incidence and mortality. These efforts coincided with other trends and changes that have had a positive impact on malaria, including a period of considerable economic growth and development, infrastructure and housing improvements, rapid urbanization, and general improvements in health systems and population health. It had been claimed that by the end of 2019, about 1.5 billion malaria cases and nearly 7.6 million deaths had been averted since the beginning of the century. However, in the latetr years, progress had stalled.[World Malaria Report 2020]

Malaria deaths reduced steadily over the period 2000–2019, from 736 000 in 2000 to 409 000 in 2019. The percentage of total malaria deaths among children aged under 5 years was 84% in 2000 and 67% in 2019. Globally, the malaria mortality rate (i.e. deaths per 100 000 population at risk) reduced from about 25 in 2000 to 12 in 2015 and 10 in 2019, with the slowing of the rate of decline in the latter years. About 95% of malaria deaths globally were in 31 countries. Nigeria (23%), the Democratic Republic of the Congo (11%), the United Republic of Tanzania (5%), Mozambique (4%), Niger (4%) and Burkina Faso (4%) accounted for about 51% of all malaria deaths globally in 2019. Malaria deaths in the WHO African Region reduced by 44%, from 680 000 in 2000 to 386 000 in 2019, and the malaria mortality rate reduced by 67% over the same period, from 121 to 40 deaths per 100 000 population at risk. In the WHO South-East Asia Region, malaria deaths reduced by 74%, from about 35 000 in 2000 to 9 000 in 2019. India accounted for about 86% of all malaria deaths in the WHO South-East Asia Region. [World Malaria Report 2020]

According to WHO’s latest World Malaria Report 2021, there were an estimated 241 million malaria cases and 627 000 malaria deaths worldwide in 2020, about 14 million more cases and 69 000 more deaths in 2020 compared to 2019. Approximately two thirds of these additional deaths (47 000) were linked to disruptions in the provision of malaria prevention, diagnosis and treatment during the pandemic. Most of the increase came from countries in the WHO African Region, with an estimated 228 million malaria cases in 2020, accountING for about 95 per cent of cases. Twenty-nine countries accounted for 96 per cent of malaria cases globally. Six countries – Nigeria (27 per cent), the Democratic Republic of the Congo (12 per cent), Uganda (5%), Mozambique (4%), Angola (3.4%) and Burkina Faso (3.4%) – accounted for about 55 per cent of all cases globally. India accounted for 83 per cent of cases in the WHO South-East Asia Region. Sri Lanka was certified malaria-free in 2016 and remains malaria-free. It is clear that crucial milestones of the WHO Global Technical Strategy for Malaria 2016–2030 have been missed in 2020 and the 2030 targets will not be met without immediate attention.

WHO recommends groundbreaking malaria vaccine for children at risk: Based on results from an ongoing pilot programme in Ghana, Kenya and Malawi that has reached more than 800 000 children since 2019, the World Health Organization (WHO) is recommending widespread use of the RTS,S/AS01 (RTS,S) malaria vaccine among children in sub-Saharan Africa and in other regions with moderate to high P. falciparum malaria transmission. [See] Oct 6, 2021
Childhood malaria episodes could be reduced by 20% – from 2.49 to 2 cases per child – during malaria transmission season if the whole population were given a drug called ivermectin every three weeks, according to the first randomised trial of its kind including 2,700 people including 590 children from eight villages in Burkina Faso, published in The Lancet.[Lancet Full Text | EurekAlert | Independent Report | Earlier Study 2010 | WHO Report 2016]
