Les infeccions de Chikungunya es multipliquen per set i la majoria es detecten a Catalunya Els brots arreu del món augmenten l'arribada de casos importats i ja s'han detectat 43 casos a tot l'Estat

🔔 Els casos de #chikungunya es multipliquen per 7 a l’Estat, amb Catalunya al capdavant.

L’augment de viatges i la crisi climàtica eleven el risc de transmissió local.

Yet there are successes:
the #Marburg Outbreak in Ethiopia that was quickly contained;
the rapid sequencing of #chikungunya in Reunion which was then used to identify spread around the world;
the rapid effects of #malaria vaccine roll-out!

Our team at #CEMA were in Isiolo yesterday, delivering cold chain solutions for sample storage & transport for the Accelerating #Chikungunya Burden Estimation to Inform Vaccine Evaluation Research Study, to maintain sample integrity & ensure reliable #data collection. #NTDs

Chikungunya virus persists in joint-associated macrophages and promotes chronic disease in mice To elucidate mechanisms of chronic CHIKV disease, we used a wild-type (WT) C57BL/6 mouse model of CHIKV infection that recapitulates many of the hallmarks of arthritic disease observed in patients infected with CHIKV14. Initially, we evaluated joint-associated tissue for signs of inflammation during the chronic stage (that is, 28 days post-infection (dpi)). This time point was selected based on previous studies35 showing immune-mediated clearance of an attenuated vaccine strain of CHIKV, but not WT CHIKV strains, from joint-associated tissues by 28 dpi. Previous studies39,40,41,42 of acute CHIKV infection in mice showed elevated pro-inflammatory markers such as IL-1β, TNF, NLRP3, major histocompatibility complex class II (MHC-II) and IFNγ. Following subcutaneous virus inoculation in the footpad, the ipsilateral ankle of CHIKV-infected mice at the chronic stage of infection also displayed an inflammatory gene expression signature characterized by heightened expression of Tnf, Nlrp3, Il1b, Ifng and H2-Aa (MHC-II) (Fig. 1a). NLRP3 is a component of the inflammasome involving caspase 1 or caspase 8, which cleave pro-IL-1β to the functional form, IL-1β43. Notably, TNF and IL-1β expression from macrophages has been implicated in cartilage and collagen destruction in RA44,45. Next, we analysed cells present in joint-associated tissue at 28 dpi using scRNA-seq (Fig. 1b)...

Line graph displays "Estimated infected individuals, % (95% Crl)" against "Age group, y". The magenta line peaks between age 10 to <15, then decreases until age 20 to <25, it increases slightly till age 35 to <40, then reduces and finally peaks at age 70 to <75.

High #Chikungunya virus seroprevalence was found among adults and schoolchildren in French Polynesia, but modeling indicates the risk of sustained transmission could increase after 2025 if social mixing patterns and population immunity change.
