Coronavirus, Be Aware And Spread Awareness
With the advancements and changes in life styles, technologies, eating habits and lot more, the diseases attacking the mankind have also changed their trends. There was a time when bacterial infections were more prevailing and were the main cause of the mortalities but then came the magical antibiotics and the problem seemed to decrease in intensity for a long time. But now again the resistance and changes of phenotypes of bacteria are posing problem with effectiveness of the antibiotics. Whereas the viruses have been a problem since long.
What Is A Virus
viruses are very small infectious agent with DNA or RNA within a protein coat that may have an envelop or may not have. It reproduces inside the cells of living hosts making thousand of its copies and causing disease to the host.
As the viruses use the metabolic pathway of human cells and integrate their nucleic material in human DNA, thus creating a problem of inevitable damage of human cells while giving antiviral drugs. This leads to restriction of the use of antiviral drugs in the very lethal diseases only.
Other method of preventing the disease is using preventive vaccines which is safe and cheap method to help us to save ourselves from the disease. The vaccines have been successfully used over long periods of time making the world free from smallpox, making poliomyelitis almost on verge of eradication and preventing millions of people all around the world against rabies, hepatitis and many more. However with the benefits of all the technologies the side effects are always there.
Viral genome can be created in laboratory making it a lot of concern of new style of warfare to damage the economies by the bio- attack. In addition as the viral disease is always highly contagious so when the travel between the world was not that easy it prevented the spread of disease on very large scale as compared to now a days when the world is global village and the spread of any viral disease is like a fire in a forest.
Corona Virus A Hot Current Issue
Coronavirus, hot issue of these days is example of all problems stated above. These are group of enveloped RNA viruses and capable of causing disease in humans and animals. Till now various strains of coronavirus have been known to cause various diseases with involvement of respiratory tract being most common in humans.
The strain called as SARS-virus is famous and known to people due to an outbreak with number of mortalities few years back. The coronavirus strain identified in the outbreak of Wuhan, China in 2020 has not been noticed in humans till now.
Signs And Symptoms
Signs and symptoms of the disease caused by it are like common cold including runny nose, sorethroat and cough. The serious complications of coronavirus are pneumonia, respiratory distress syndrome and death. No vaccine or antiviral drug is known to be there and effective against it. Prevention against the spread of disease can just help us. Washing hands properly with a disinfectant, keeping least hand contact with eyes and respiratory tract and isolating the patient from public specially and even within home to prevent the spread is required.
Coronavirus spreads through sneezing, coughing, infected hands,breath and the things person comes in contact with. Due to spread in a large area the symptoms of common cold should not be taken light. Proper consultation with doctor.
throat and nasal swab cultures and complete blood picture should be sought. Though the symptoms of mild coronavirus infection will go away itself within a week but proper diagnosis is important to prevent the complications as it can cause leading to mortality.
The patients already been effected have to be given plenty of fluids and bed rest. Ibuprofen or acetaminophen should be used for the cases of fever. Antibiotic use in cases of superimposed bacterial infection. Close contact with the patient and things of his use should be avoided. The patient should also be encouraged to wash his hands properly and discard the tissue papers or handkerchiefs soaked with his nasal secretions properly. Doctors should treat all the patients with flu-like symptoms with their protective gears.
The efforts of all of us can help us to fight against this pandemic and awareness can lead to decrease mortalities. Know urself about it and let others also know about it because prevention is better as it can have deadly results as well.
