ZIKAlliance project: Zika vector competence data reveals risks of outbreaks
A publication published this summer looks back at the contribution of the European ZIKAlliance project, launched in 2016 following the Zika epidemic in the Pacific Islands and America. A global analysis of the competence of potential vectors was carried out, the most comprehensive study of vector competence to date using the same protocols. This study reminds us that vector-borne diseases are...

Hepatitis B: towards better treatment for infected individuals in Africa
With 82 million people currently infected in Africa, the hepatitis B virus represents a major health threat. Early treatment can considerably reduce the risk of complications associated with the disease. In a recent analysis, scientists challenged the suitability of the diagnostic tests used in sub-Saharan Africa and called for more optimized treatment for local populations.

Health crises, information crises: exploring the roots of the term "infodemic"
How do the epidemiological and media dimensions of a health crisis fit together? How is the spread of a virus linked to the spread of information about it? Several scientists, communication experts and ethics specialists came together to explore these questions at a conference held at the Institut Pasteur in December.

The tiger mosquito can transmit the chikungunya virus in temperate conditions
The tiger mosquito Aedes albopictus, native to Southeast Asia, is one of two vectors for transmission of the chikungunya virus to humans. Scientists at the Institut Pasteur and Université Paris Cité have shown that this mosquito can acquire the ability to transmit the chikungunya virus as effectively at 20°C as at 28°C. The spread of the tiger mosquito in temperate climates could therefore result...

Crimean-Congo hemorrhagic fever
Crimean-Congo hemorrhagic fever (CCHF) is a disease caused by a virus of the same name. In most cases, the infection is mild, but it can be severe or even fatal. The main route of transmission of the virus to humans is bites from ticks of the genus Hyalomma.

COVID-19: the persistence of SARS-CoV-2 in the lungs and the role of innate immunity
One to two weeks after contracting COVID, the SARS-CoV-2 virus generally becomes undetectable in the upper respiratory tract. But does that mean that it is no longer present in the body? To find out, a team from the Institut Pasteur specialized in HIV, in collaboration with a French public research institute, the Alternative Energies and Atomic Energy Commission (CEA), conducted a study on lung...

Smoking has long-term effects on the immune system
Like other factors such as age, sex and genetics, smoking has a major impact on immune responses. This is the finding recently made by a team of scientists at the Institut Pasteur using the Milieu Intérieur cohort of 1,000 healthy volunteers, established to understand variability in immune responses. In addition to its short-term impact on immunity, smoking also has long-term consequences. For...

HIV-AIDS: natural killer cells that target HIV
African green monkeys are able to live while being infected with the simian immunodeficiency virus (SIV) without ever developing AIDS. Their hint? Directly eliminate infected cells, without causing an inflammatory reaction that the virus could use to its advantage.

Lyme disease (Lyme borreliosis)
Lyme disease, also known as Lyme borreliosis, is a tick-borne disease. It is the most widespread vector-borne disease in the entire northern hemisphere. Its incidence continues to rise at global level as a result of demographic and environmental factors, including climate change.
