Trends of measles in Nigeria: A systematic review

Sahel Medical Journal, 2016
Background: Measles, a highly infectious viral disease, is endemic in developing countries with a peak of transmission from October to March. The case fatality rate of measles in the developing countries stands at around 3-5%; this could be as high as 10%

Herbivory‐Induced Stomatal Opening Triggers the Dispersal of an Invasive Insect Herbivore

Advanced Science, EarlyView.
The invasive leafminer Phthorimaea absoluta uniquely manipulates plant defenses by inducing stomatal opening in tomato. This response, mediated by the stomatal regulator IQM1, enhances the release of the repellent volatile benzaldehyde. This volatile triggers the dispersal of adult moths, facilitates colonization of new hosts, and leads to rapid ...

Targeting β2‐Adrenergic Receptor Stability With Lycorine Reveals a Host‐Directed Pathway for Antiviral Defense Against Poxviruses

Advanced Science, EarlyView.
Chronic stress drives autophagy‐mediated β2‐AR degradation, impairing antiviral immunity and promoting poxvirus lethality. Lycorine directly stabilizes β2‐AR to restore host defense, suppress excessive inflammation and improve survival. ABSTRACT Psychological stress is a pervasive yet poorly understood modulator of infectious disease outcomes. Here, we

Modeling rapidly disseminating infectious disease during mass gatherings

BMC Medicine, 2012
We discuss models for rapidly disseminating infectious diseases during mass gatherings (MGs), using influenza as a case study. Recent innovations in modeling and forecasting influenza transmission dynamics at local, regional, and global scales have made ...

Decoding Viral Transmission Dynamics in Structured Populations Using a Microfluidic Herd‐Immunity‐on‐a‐Chip Platform

Advanced Science, EarlyView.
A microfluidic Herd‐Immunity‐on‐a‐Chip experimentally recreates structured contact networks to quantify viral transmission dynamics. By controlling susceptible, infected, and non‐susceptible populations, the platform reveals how contact topology governs the reproduction number, outbreak propagation, herd‐immunity–like behavior, and intervention ...

Epidemics after Natural Disasters

Emerging Infectious Diseases, 2007
The relationship between natural disasters and communicable diseases is frequently misconstrued. The risk for outbreaks is often presumed to be very high in the chaos that follows natural disasters, a fear likely derived from a perceived association ...

Marked Rise in Replikin Counts in H5N1 Influenza Virus Localized to Lethality Gene p B1. [PDF]

, 2011
: Virus outbreaks have been found to be related to the concentration of a new class of genomic peptides, Replikins^1^. The eight genes of H5N1 influenza virus were analyzed for the distribution of Replikin Counts (number Replikins /100 amino acids) in 2 ...
