To show just
how rapidly Zika gained a foothold in the Americas, we created a GIF displaying all
of the places that the Zika
virus has spread through local transmission since the start
of the
outbreak:
Although Zika's path was documented starting in 2015 through records
of human cases, less was known about
how the
virus spread so silently before detection, or
how outbreaks in different parts
of Central and South America were connected.
Researchers studied the structure
of proteins from one strain
of the H7N9
virus that caused the
outbreak and tested
how strongly one
of the proteins bound to molecules on the surfaces
of bird and human cells.
Thus, there is limited knowledge about the extent and mechanisms
of transmission during the current
outbreak in the Americas and even less about
how the
virus is circulating in Asia.
In the past two years, genetic sequence information
of the flu -
virus protein hemagglutinin from only two influenza strains from India has been deposited into publicly available influenza databases, making it difficult to determine exactly which strain is causing the new
outbreak, and
how it differs from previous strains.
The most recent
outbreak in 2014 has illustrated the lack
of understanding
of viral pathogenesis and highlighted the need for increased study
of how the Ebola
virus replicates.
Fifteen months after the 1999
outbreak of West Nile
virus in New York City, which sickened 62 mostly elderly people and killed seven, scientists are still hard pressed to predict
how abundant the
virus will eventually become or
how serious a public health threat it will pose.
For the paper, «Transmission dynamics and control
of Ebola
Virus Disease (EVD)
outbreak in Nigeria, July - September, 2014,» published today in Eurosurveillance, researchers used epidemic modeling to project the size
of the
outbreak in Nigeria if control interventions had been implemented during various time periods after the initial case and estimated
how many cases had thus been prevented by early initiation
of interventions.
Although we don't know
how many health workers reported being ill and were assessed to decide if they needed to be tested, protocols for the management
of possible exposure to the
virus, and for the management
of illness, may need reviewing and to be standardised across organisations that deploy staff to
outbreaks.
A global team
of researchers has sequenced and made publicly available more than 200 additional genomes from Ebola
virus samples to capture the fullest picture yet
of how the
virus is transmitted and
how it has changed over the course
of the recent
outbreak
And the
virus can become genital herpes through physical contact, so no matter
how tempting, best to lay off any kissing or intimacy while one
of you has an
