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...

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...

Indian Ocean surface temperature could help anticipate dengue outbreaks
Although dengue outbreaks cannot be prevented, it is possible to anticipate them. An international research team including scientists from the Institut Pasteur and Beijing Normal University in China has recently identified a global climate indicator that may help improve predictions about the magnitude of dengue outbreaks several months in advance. This indicator, which can be used for any world...
