Neglected tropical diseases are often associated with social exclusion as well as physical suffering. One billion people around the world suffer from these diseases.
Every year, 1.7 billion people, most in the world’s poorest areas, are affected by NTDs. The diseases cause suffering, stigma, disability and sometimes death.
COVID-19 variants are the products of the evolution of the SARS-CoV-2 virus. They arise via mutations, but other forces also have roles to play in the generation and transmission of variants.
This insect’s unique reproductive biology could lead to new ways to control the species in the environment – and prevent the deadly sleeping sickness it spreads to people.

Mathematical modelling tools may predict where tsetse flies are being driven to extinction.
Although there have been global efforts to eliminate parasites, some parasites and vectors will have survived attack because they have evolved resistance.
Perhaps because we all need sleep, we have an enduring interest in sleep disorders such as narcolepsy, which causes a constant irrepressible need for sleep.
New research upends the previous theory that tsetse flies – and the disease they carry – were the main reason the spread of livestock domestication in Africa stalled out for a thousand years.
After a decade of research, an international team decoded the genes of the tsetse fly – the transmitter of trypanosomiasis, or sleeping sickness. Human trypanosomiasis is a widespread tropical disease…
Since mid-December the nascent South Sudanese state has collapsed into inter-ethnic violence, sparked by a skirmish within the country’s Presidential Guard. At least 1,000 people have been killed and around…
