Viral Infectious Diseases

Viruses are minute particles of genetic matter (either DNA or RNA) that are encompassed by a protein layer. Some viruses also have a fatty "envelope" covering. They are incapable of reproducing on their own. Viruses depend upon the organisms they infect (hosts) for his or her very survival. Viruses get a nasty rap, but they also perform many important functions for humans, plants, animals, and therefore the environment. For instance, some viruses preserve the host from other infections. Viruses also participate within the process of evolution by transferring genes among different species. In biomedical studies and discoveries, scientists utilize viruses to place new genes into cells. Viruses can affect many areas within the body, including the reproductive, respiratory, and gastrointestinal systems. They can also influence the liver, brain, and skin. Research reveals that those viruses are implicated in many cancers as well. A virus infection may be a proliferation of a harmful virus inside the body. Viruses cannot reproduce without the help of a number. Viruses infect a number by introducing their genetic material into the cells and hijacking the cell's internal machinery to form more virus particles. With a lively virus infection, an epidemic makes copies of itself and bursts the host cell (killing it) to line the newly-formed virus particles free. Viruses are often transmitted during a sort of ways. Some viruses can spread through touch, saliva, or maybe the air. Other viruses are often transmitted through sexual contact or by sharing contaminated needles. Insects including ticks and mosquitoes can act as "vectors," transmitting an epidemic from one host to a different. Contaminated food and water are other potential sources of virus infection. Some of the common viral infections include:

  • Zika virus
  • Hepatitis C
  • Dengue Fever
  • H1N1 swine flu
  • Ebola
  • Middle East respiratory syndrome (MERS-CoV)
  • Hanta fever
  • Respiratory Viral Infections (Rhinovirus, Seasonal Influenza)
  • Viral Skin Infections (Molluscum contagiosum, Herpes simplex virus-1 (HSV-1), Varicella-zoster virus)
  • Foodborne Viral Infections (Hepatitis A, Norovirus, Rotavirus)
  • Sexually Transmitted Viral Infections (Human papillomavirus, Hepatitis B, Genital herpes, HIV)
  • West Nile virus (WNV)
  • Viral meningitis
