Recent studies that have been analyzing the disease established that some Ebola patients may not show outer symptoms of carrying the disease, which raises new questions in regards the affection.
The study was conducted by an international team of scientists which published their reports in the PLoS Neglected Diseases journal which belongs to the Public Library of Sciences.
According to their research, 25 percent of those infected with the disease may have presented minimal or no symptoms of Ebola.
In between 2014 and 2016, the Ebola pandemic affected countries located mostly across the African continent and killed over 11,000 of the more than 28,000 detected Ebola patients.
This new study may put to the question the official statistic as new information are starting to surface in regards to Ebola’s manifestation and symptoms.
The fact that a disease does not always manifest outer symptoms is not uncommon or unknown. Still, researchers were surprised to discover that this may also seem to be the case with Ebola.
As the disease acquired a quite notorious reputation due to its awful symptoms and its deadly nature, its possible minimal manifestations were hard to predict.
Most Ebola patients were infected due to bodily fluids, which also made them highly contagious. As during the outbreak, researchers were busy with containing and stopping the crisis, studies of the disease are just beginning to appear.
One such study, the aforementioned one, sought to determine if the virus generally presented only severe symptoms.
As such, Stanford University’s Dr. Gene Richardson and his Sierra Leone and United States colleagues collected blood samples from the Kono District-based Sukudu village.
The team tested the blood of 132 people that were not related or in the vicinity of Ebola patients. A further 187 samples collected from people that were near to the sufferers or that shared common spaces were tested.
Out of the 132 aforementioned people, 14 tested positive for Ebola antibodies although 12 of them could not even remember having had a fever during the time.
As health workers kept a watchful eye over the population, it is unlikely that any villager could have hidden their disease.
The research data went to show that a significant number of Ebola disease transmissions may have gone completely undetected.
With the new discovery, the estimated numbers of both Ebola patients and survivors may change as quite a few cases may have remained undetected due to their lack of symptoms.
According to the aforementioned Richardson, researchers are expecting to find quite a number of previously undetected survivors.
The preliminary data does not show whether the Ebola patients that do not present symptoms could have transmitted the virus. As such, further research will be made in that area as well.
The study’s team will now be turning their attention to other areas which were affected by the outbreak so as to try to determine the number of survivors.
Their results may also help towards a better understanding of Ebola and its actual effects and damages, as new information continues to appear.
