HANTAVIRUS: An Aerosolized Virus

Viruses are small microscopic or submicroscopic organelle which depend on living organisms (host) for their reproduction and growth. The study of viruses known as virology. Viruses may attack all types of living organisms and plants too such as tobacco mosaic virus. They contain genetic material DNA or RNA which contains proteins, capsid and envelope. The shape of the viruses may not be particular and vary from virus to virus. Transmission virus mainly occurs by arthropods through infected specimen urine, feces and transmission of host through contaminated food and water by vectors. To the animals transmission of virus through blood sucking arthropods. And some of viruses such as influenza are transmitted through coughing and sneezing. Fecal to oral route transmitted viruses may cause gastroenteritis. Some are transmitted through sexual contact such as HIV. From these types of viruses hanta virus is the one of the viruses which is transmitted through rodents. Hanta belongs to the family of bunyavirus. They - ve RNA containing viruses. It is an enveloped virus containing three single standard segments such as S-segment, M-segment and L-segment. The S is a small segment, M is a medium segment and L is a large segment. These viruses may replicate into the cytoplasm of the cell. The shape of these viruses is about spherical shape and having the size of 80 - 120 nm. These viruses may especially be found in Asia particularly in China, Russia and Korea. These viruses may cause HFRS (hemorrhagic fever with renal syndrome), HPS(Hantavirus Pulmonary Syndrome).
