Summary
French Polynesia experienced a dengue virus serotype 2 (DENV-2) outbreak in 2019, the first since 1996-97. With limited population immunity, a large epidemic is possible, posing a risk for imported cases in mainland France.
Area of Science:
- * Virology
- * Epidemiology
- * Public Health
Background:
- * French Polynesia last experienced a dengue virus serotype 2 (DENV-2) outbreak in 1996-97.
- * DENV-2 re-emerged in French Polynesia in February 2019 via a traveler, followed by local transmission.
- * The population's lack of immunity to DENV-2 heightens the risk of a widespread epidemic.
Purpose of the Study:
- * To report the emergence and initial spread of a DENV-2 outbreak in French Polynesia.
- * To assess the potential for a large-scale epidemic and imported cases in mainland France.
Main Methods:
- * Case detection and diagnosis of DENV-2 infections.
- * Monitoring of outbreak progression and case numbers.
- * Assessment of population immunity status.
Main Results:
- * A DENV-2 outbreak was declared on April 10, 2019.
- * As of June 24, 2019, 106 cases were reported.
- * The majority of the population remains susceptible to DENV-2.
Conclusions:
- * The re-emergence of DENV-2 in French Polynesia poses a significant public health threat.
- * A large epidemic is anticipated due to widespread population susceptibility.
- * Vigilance is required to prevent imported DENV-2 cases in mainland France.

All meta-directing substituents are deactivating groups. These substituents withdraw electrons from the aromatic ring, making the ring less reactive toward electrophilic substitution. For example, the nitration of nitrobenzene is 100,000 times slower than that of benzene because of the deactivating effect of the nitro group. The first step in an electrophilic aromatic substitution is the addition of an electrophile to form a resonance-stabilized carbocation. The energy diagrams for...

01:202° Amines to N-Nitrosamines: Reaction with NaNO2
5.4K
Secondary amines react with nitrous acid to form N-nitrosamines, as depicted in Figure 1. Nitrous acid, a weak and unstable acid, is formed in situ from an aqueous solution of sodium nitrite and strong acids, such as hydrochloric acid or sulfuric acid, in cold conditions. In the presence of an acid, the nitrous acid gets protonated. The subsequent loss of water results in the formation of the electrophile known as nitrosonium ion.

Kinetic Studies and Significance
In a chemical reaction, a relationship exists between the concentration of reactants and the rate at which the reaction proceeds. The study to measure this relationship is known as the kinetics of a chemical reaction. Kinetic studies are used to deduce the rate law of a chemical reaction, which provides information about the species involved during the transition state of the rate-determining step. Thus, kinetic studies help to derive the mechanism of a...

The kinetic studies of SN2 reactions suggest an essential feature of its mechanism: it is a single-step process without intermediates. Here, both the nucleophile and the substrate participate in the rate-determining step.
The presence of the more electronegative halogen in the substrate creates a polarized carbon-halide bond. The halide pulls the electron cloud generating an electrophilic center at the carbon atom. Thus, the carbon atom carries a partial positive charge while the halide has a...

11.7K
An SN2 reaction of an alkyl halide is a single-step process in which bond formation between the nucleophile and the substrate and bond breaking between the substrate and the halide occurs simultaneously through a transition state without forming an intermediate.
When the nucleophile approaches the electrophilic carbon with its lone pairs, the halide acts as a leaving group and moves away with the electron-pair bonded to the carbon. Dotted partial bonds represent the bonds being formed or broken...

11.6K
In an SN2 reaction, the nucleophilic attack on the substrate and departure of the leaving group occurs simultaneously through a transition state. As the nucleophile approaches the substrate from the back-side, the configuration of the substrate carbon changes from tetrahedral to trigonal bipyramidal and then back to tetrahedral, leading to an inversion in the configuration of the product.
If the substrate is an achiral molecule at the α-carbon, the inversion of configuration is not...
