Countries in the early stages of outbreaks should try to contain the disease, she said.
The spread of chikungunya into rural areas during the later stages of outbreaks in India further confirmed the potential of Ae. albopictus mosquitoes in transmitting CHIKV (15 ).
For example, radiographs and medical charts will need to be reviewed to identify highly anomalous findings or groupings of aberrant findings that would be expected to be present at early stages of outbreaks.
Recent severe, extensive, and synchronous bark beetle outbreaks have motivated research into methods for surveying the location, extent, and attack stage of outbreak using remotely sensed data.
Our survey conducted at the initial stage of outbreak indicated that perceptions about the risks associated with 2009 (H1N1) pandemic influenza, as well as interest in pharmaceutical interventions and precautionary activities, showed changes over time and variations over geography and demography.
In order to help initiate and direct staged response activities, the expert meeting identified the following stages of an outbreak: 1. Outbreak alert: when several alert signals point to a possible imminent dengue outbreak.
Reporting delays can undermine the ability of public health professionals to implement control measures targeting the contacts of infectious people during the very early stages of an outbreak of a disease, including an outbreak of pertussis [ 19].
The inference of R0 during the early stages of an outbreak is of high utility in the early stages of an outbreak as it enables control and infection containment strategies to be implemented effectively, and outbreak responses to be co-ordinated.
Having tools ready to facilitate disease control and surveillance in critical stages of an outbreak can save time, aid in preventing further spread and thus minimise costs and consequences of the outbreak.
Recent developments include techniques for estimating R 0 from the initial stages of an outbreak [11], [12] and a model to ascertain the effect of a delay between the onset of an outbreak and the implementation of public health policies aimed at controlling disease spread [13].
