5 unique viruses that are still mystery for scientists

Undiagnose Hemorrphagic Fever SyndromeVirus means poison and for common crowd with little knowledge of science, the word sounds vicious. Virus was first studied by Russian biologist Dmitri Ivanovsky in 1892. He studied the tobacco mosaic virus. Since then, over 5,000 different type of virus have been documented with details. There are millions of types of viruses and scientists keep discovering new types. The virus is dead outside host body, and activates after entering into it. However, some of them are unique and still mystery for scientists. Some of them are deadly to human kind, while others target only single cell organism or insects. For instance, following five viruses:

Human herpesvirus
HHV-6A DNA, also known as infertility virus, it believed to be rare and responsible for many unexplained cases of infertility in women. Study of a group of 30 infertile females had shown presence of the virus in the endometrium of almost half of the studied group. Further studies suggest doctors couldn’t diagnose the cause of fertility in one in 70 women under the age of 44. The virus attacks the womb and make it unfit to host an embryo. The virus still remains a mystery.

A mysterious viral outbreak has jolted South Sudan where over 51 suspected cases including 10 deaths were reported since 2015. Infected people reported unexplained bleeding, fever, fatigue, headache and vomiting. Samples of 33 patients were shipped to WHO and other premier health research institutes across the world. However, none of them could explain the symptomatology and lab tests still continue in a hope to identify origin and agents associated with this mysterious virus. Another fact about the virus is that 70 percent of the victims were under 20-years.

America witnessed a wave of Flaccid paralysis caused by mysterious virus – the enterovirus EV-D68. The virus is believed to be a relative of the polio virus. The children experienced weakness, paralysis and reduced muscle tone. Researchers presume that this abnormal condition may be caused by damage caused to the nerves associated with the involved muscles. In this state, the victim becomes limp, unable to contract the muscles. At worse, it can lead to paralysis of respiratory muscles resulting in eventual suffocation of the victim.

SIRV2 VirusSIRV2-virus
Discovered recently by scientists, the virus can survive in highly acidic conditions by infecting a microbe called Sulfolobus islandicus. It is found in acidic springs, living in temperatures above 80 degrees Celsius. Scientists consider it as an opportunity to study its mechanism of resistance to heat, desiccation, and ultra-violate radiations. The results can help human kind to design a DNA package for gene therapy.

Black Widow Black Widow Virus
Very recently, scientists were surprised when they discovered an unusual virus in which one-third of the virus’s genes are animal-like. The genes matched up with the DNA of toxin foun din black widow spider venom. It primarily targets the bacteria but has found a way to infiltrate animal cells too. The virus is one of its kinds that can infect multiple domains and it can take bits from different genes and put them together to form his super gene. It is still not clear to scientists whether the spider stole the genomes of the virus vice-versa.
