At first, the group's experts suspected Lassa fever, a viral disease endemic in West Africa.
Because this is not the first outbreak of Ebola, it will not be the last,and there are many other microbes out there that are lying in wait, like Lassa virus and others.
The team tested their new model using Lassa fever, a disease that is endemic across West Africa and is caused by a virus passing to people from rats.
However, the new findings show that high levels of non-neutralizing immunoglobulin G(IgG) antibodies that bind to the Lassa virus surface protein correlate with protection against Lassa virus.
Lassa fever, Rift Valley fever, Marburg virus, Ebola virus and Bolivian hemorrhagic fever are highly contagious and deadly diseases with the theoretical potential to become pandemics.
It can be said that Ebola is more dangerous as it has a higher risk of fatality,however it is more rare than Lassa fever, which affects up to 500,000 people annually, with a death toll of about 5000.
This is okay in the case of Lassa fever which only has a fatality rate of 20%, allowing 80% of patients to recover, however Ebola kills between 25% and 90% of its patients, with the average being 50%.
In 1969 missionary nurse Laura Wine fell ill with amysterious disease she contracted from an obstetrical patient in Lassa, a village in Borno State, Nigeria.[5][6][7] She was then transported to Jos, Nigeria where she died.
Lassa fever or Lassa hemorrhagic fever(LHF) is an acute viral hemorhagic fever caused by the Lassa virus and first described in 1969 in the town of Lassa, in Borno State, Nigeria.
The three disease targets are:Middle Eastern Respiratory Syndrome(MERS), Lassa fever, and the Nipah virus(NiV)- all of which are highly contagious, and currently have no vaccines or treatments in the pipelines.
Lassa fever is known to be endemic in Benin(where it was diagnosed for the first time in November 2014), Guinea, Liberia, Sierra Leone and parts of Nigeria, but probably exists in other West African countries as well.
Scientists in the Sabeti lab had successfully used baits, which are molecular probes made of short strands of RNA or DNA that pair with bits of viral DNA in the sample,to analyze the Ebola and Lassa virus genomes.
NP of Lassa virus is reported to have an exonuclease activity to only dsRNAs. dsRNA exonuclease activity of the NP leads to counteract IFN responses by digesting the PAMP which leads to the evasion of host immune responses.
The Ebola and Zika viruses, now well known, both originated in wild animals,as did many others including Rift Valley fever and Lassa fever that affect thousands already and are predicted to spread with changing environmental factors.
It is likely that a vaccine could be found for Lassa- reducing the possibility of an outbreak becoming a global health emergency- but as with other epidemic diseases that mainly affect poorer countries, progress has stalled.
Ribavirin has effects on RNA viruses such as respiratory syncytial virus(RSV), many strains of influenza A and B,parainfluenza, Lassa fever, rotavirus, measles virus, mumps virus, enterovirus 72(formerly known as hepatitis A virus), yellow fever virus.
Just two weeks ago we published a paper in Nature Microbiology on a metagenomic sequencing technique that enables you to rapidly identify virtually every RNA viral pathogen, including Zika virus, West Nile virus, Ebola virus,Marburg, Lassa, yellow fever, influenza, any virus.
Health workers caring for patients with suspected or confirmed Lassa fever should apply extra infection control measures to prevent contact with the patient's blood and body fluids and contaminated surfaces or materials such as clothing and bedding.
The Japanese National Institute of Infectious Diseases(NIID) in Tokyo has begun tests on live viruses of Ebola and four other types of haemorrhagic fever-Marburg, Lassa, Crimean-Congo and South American- in an attempt to make diagnoses more accurate and improve detection methods.
The pathogenesis of the Lassa virus remains unclear, but it has been shown that the main targets of the virus are antigen-presenting cells(mainly dendritic cells) and endothelial cells.[25][26][27] Also, it is reported that Lassa virus prevents a host's innate immune system by NP activity.
Ben Neumann, a virologist at Britain's Reading University who studies Ebola and other viruses and their effects,notes that Lassa virus, which comes from West Africa and causes a similar disease to Ebola, has also been reported as having longer-term health effects.
While Ebola virus is mainly found in Central Africa(the current outbreak in Guinea is far west of previous outbreaks), other viruses that cause viral haemorrhagicfever are distributed more widely- Lassa fever(West Africa), hantavirus(east Asia), Junin(Argentina), Crimean-Congo(mainly Central Asia and eastern Europe).
Although malaria, typhoid fever, and many other tropical infections are much more common,the diagnosis of Lassa fever should be considered in febrile patients returning from West Africa, especially if they have had exposures in rural areas or hospitals in countries where.
