Viruses like particles are something which can really make us ill. These particles are creatures that depend on cells from other entities in order to reproduce. A virus will attach itself to one of your cells and then release enzymes into the cell. The enzymes trigger the production of more of the virus. The new virus which is a single virus like particle eventually destroys the cell and move on to find new cells, where they will create even more of the virus.This cycle can happen very fast. The virus spreads rapidly in your body, attacking different cells. The viral attack makes you sick, producing symptoms like a sore throat, a runny nose, and aching muscles. Your body fights back, usually beating off minor viruses with a fever. How these particles enter in our body? Detailed medical studies have found that especially those using infection control interventions; have indicated that the primary mode of transmission for the most common respiratory and gastrointestinal viruses acquired by children and adults within schools is close contact with infected individuals or touching infectious discharges that infectnon-living objects. There are some of the openings from where the virus like particles gets to enter in our body. The main mediators to these viruses are from our respiratory systems. After entering in the body some very alarming respiratory infections occur in small school going children and through them to their families, and the main enemy are the respiratory syncytial virus, picornaviruses particularly the genera enteroviruses, rhinoviruses, and viruses, influenza, adenoviruses, parainfluenza viruses, measles, and human respiratory coronaviruses. Respiratory viruses takeshelter primarily as nasal or oral discharges such as runny nose or projected into the air by sneezing, coughing, spitting, or speaking. Most are transmitted from the infected person to others by any of three possible mechanisms mentioned above. Specific viruses may be spread by more than one of these mechanisms. Small-particle aerosols are usually generated by coughing or sneezing and may traverse into some certain distances, can occur without close or direct contact with the infected person or the infectious secretions. Evidence is emerging that quiet breathing can also generate small particles. How they capture human body? Researchers have found that Viruses like particles do not have a membrane as all other cells do, and depend on on host cells to survive as they behave like parasites. Viruses can be thought of as sub-cellular parasites which infect living cells and then take over the cell's metabolic processes to produce more viruses. Viruses are not cells but they contain substances characteristically found only in living cells.Viruses cause disease. A virus may lie dormant for many years, yet, when it comes in contact with a suitable living cell, an amazing thing happens. The tiny virus particle captures the host cell and 'forces' it to make hundreds of copies of itself. Eventually, the host cell dies and bursts open. The freshly made virus like particles leaks and goes on to infect other cells. Among the many diseases caused by viruses are smallpox, polio, influenza, chickenpox, measles, cough and colds.
