Introduction
In recent years of span in between 2014-2018 Ebola viral disease
has spread as epidemic but the emergence of the disease frst occurred
in 1976 near the Ebola River, Democratic Republic of Congo. After
that the virus has emerged periodically and affected several African
countries. Among the reported cases of viral infection around 61% of
the cases are fatal by nature.

Among the family of viruses Filoviruses
is the family under which Ebola virus genera comes that contains
the genus Cuevavirus. The six species under the Ebolavirus are well
known as follows, Zaire ebolaviruses (Ebola virus (EBOV)), Sudan
ebolavirus (Sudan virus), Bundibugyo ebolaviruses (Bundibugyo
virus), Tai Forest ebolaviruses (Taï Forest virus), Reston ebolavirus
(Reston virus (RESTV)) and the most notorious specie Bombali
ebolaviruses (Bombali virus). Major floviruses cause hemorrhagic
fever in humans, with high rate of fatality case and Ebola viral disease
is a disease which has set of symptoms like severe headache, fever,
muscle pain, fatigue along with diarrhea, nausea, abdominal pain and
unexpected hemorrhage(Figure 1).

Host and disease spread
There is some conception about the reserved host source for the
spread of Ebola to be African fruit bats which is still a research feld to
explore but some evidence reveals that recent, Bombali virus has been
found in samples of bats collected in Sierra Leone. Major spread occurs
via the use of contaminated needles and syringes causing transmission
and amplifcation of the disease. In 1989, there was a true fact revealed
the Reston ebolavirus found in research monkeys imported from the
Philippines that the virus can transmit through droplets in the but no
such viral transmission is possible in humans. During the period of
2014-2015 Ebola outbreaks in West Africa, majority of transmission
events were between family members and due to direct contact with
the dead bodies who died from viral disease was proved to be one of
the most dangerous process.

Detection techniques
Among the detection techniques majorly four types of detection
techniques are being focused those are (a) cell culture assay, (b)
antibody detection assay, (c) protein antigen detection technique and
(d) RT-PCR technique. In cell culture assay techniques to confrm the
presence of virus the viral isolation in cell culture, typically using
Vero E6 African Green monkey kidney cells are being carried out.
The propagated virus is visualized by electron microscopy directly
or indirectly visualized by immuno fuorescence microscopy within 1
to 5days of inoculation. Due to the requirement of bio safety level 4
containment, the technique is typically restricted to research and public
health laboratories. Next in antibody detection, ELISA is the basis of
it. In 1995 out break frst IgM and IgG ELISAs were employed by the
CDC during with persistence of IgG and the fnal time point tested was
day 117. In recent studies during the 2014-2015 epidemics the onset
of IgM and IgG was between 6 and 11days and 9 and 11days after the
viral symptom onset respectively. Further the study revealed that the
IgM antibody responses are variable, with the onset of detection from
2 to 11days but the IgG responses are detectable in the second week of
illness and persist for years which is useful tool for population-level
more studies and detection. However, in Protein Antigen Detection,
the viral protein antigens circulating in blood provides a dependable

Abstract
Although there is a bunch of disease and disorders are there, Ebola is one of the leading
diseases in the world map causing numerous affected beings per year. The viral modifcation
with time and wide spreading boundaries are causing more red alters. So the review is
focused on the life cycle of the virus, its spread detection technique and new age strategy
for drug development to under the control the condition in nutshell.
