Essay on Pandemic covid-19
THe World Health Organization (W.H.O) has declared COVID-19 a pandemic COVID-19 stands for coronavirus disease 2019 and is caused by the severe acute respiratory syndrome coronavirus - kernel viruses are a large family of viruses that are common in people and lots of different species of animals including cats and bats common human kernel virus typically causes an upper respiratory tract infection like the common cold.
Most people get infected with one or more of these viruses at some point in their lives the human coronavirus infection typically resolves on its own with basic rest when feeling depressed infrequently the corona viruses which infect animals can evolve and become a new virus which then infect and spread between people important examples of these include severe acute respiratory syndrome coronavirus or SARS in 2003 and the Middle East respiratory syndrome coronavirus also known as MERS in 2019
In wuhan a town in the whom a state in china detected a number of unusual cases of pneumonia in the hospital these patients most especially presented with clinical symptoms of dry cough this Nia fever and bilateral lung infiltrates on imaging the corona virus cases were eventually reported to the World Health Organization state office in China on the 31st of December 2019 Lots of the cases were reported and searches for the sores have shown the one and seafood market a wet market as the origin
The marketplace was where a large variety of vertebrate and invertebrate animals wild court and farm raised are sold on January 1st said markets were closed also on January 12-2020 China shares the genetic sequence of the novel coronavirus which will be very significant for the other states as they developed specific diagnostic tests at the end of January
The kernel virus was discovered to have originated from wild bats and belonged to the same group as SARS hence this corona virus is also known as SARS coronavirus two by January 30th the novel coronavirus outbreak was declared an emergency On February the 11th 2020 the World Health Organization announced that the official name of this disease would be COVID-19 a shortened version of Corona virus disease 2019 by March 11th COVID-19 was declared a pandemic.
It's a global epidemic of a disease something not to be taken lightly Kovan 19 is a concern because it is highly transmissible the amount of cases are increasing at a rapid rate and this is a result of the virus being infectious but also due to an increase in awareness and the availability of the diagnostic kits as of March 15th COVID-19 has affected more than 150,000 people worldwide and carries a mortality rate of about 3 percent to put it into perspective.
If you compare those figures to another coronavirus outbreaks such as SARS in 2003 had just over 8,000 cases with a mortality rate of about nine point five percent and MERS in 2012 had a roughly 2,500 cases with a mortality rate of about 35 percent despite having a lower mortality rate than its predecessors three percent is still quite significant especially with the rapidly rising number of cases you can imagine for every 100 cases three people may die.
If we compare these statistics of coronavirus into the seasonal influenza caused by the influenza virus which affects millions each year the mortality rate of the flu season of influenza is less than 0.2percent COVID-19 results from SARS coronavirus to a beat occurred a virus it is composed of a single-stranded ribonucleic acid RNA.
The virus targets and infects the respiratory system and is transmitted by contact droplets and fomites from another infected individual who is symptomatic or even asymptomatic the incubation period the time from infection to appearance of symptoms is about 2 to 14 times the average age effected is 47 years old and interestingly children are rarely symptomatic both males and females are affected roughly alike.
The classic symptoms of covid-19 is a fever dry cough sore throat and shortness of breath these symptoms can progress and people may develop pneumonia and even acute respiratory distress syndrome requiring intensive care the mortality rate as mentioned for COVID-19 is 3 percent approximately but that increases with age especially for those above 60
But more significantly for those above 80 years of age mortality rate also increases with comorbidities such as diabetes heart disease kidney disease investigation findings of people infected with COVID-19
are lymphocyte open iya so low lymphocyte count in the blood and CT chest in patients most commonly demonstrates ground glass or pacification consistent with viral pneumonia identification of covid-19 is made with PCR identifying the COVID-19 barrel RNA
The genetic material the principal treatment of covid-19 is supportive care at present no effective treatment is available for COVID-19 and this includes antivirals antibiotics steroids traditional medicine and there's absolutely no vaccine however a randomized multicenter controlled clinical trials are underway looking at different treatment choices as we speak.
The Crow Navarre should not be confused with the influenza virus which causes the seasonal influenza covid-19 and influenza virus are very similar they have similar demonstrations which is they both cause a respiratory disease that presents as a wide range of illness from asymptomatic or mild through to severe disease and death secondly both viruses are transmitted by contact droplets and fomites as a consequence the same public health measures such as hand hygiene and good respiratory etiquette are significant actions all can take to prevent infection the difference between the viruses is the influenza virus which causes the seasonal flu.
Includes a vaccine available annually to help prevent and reduce the symptoms of influenza whereas the corona virus don't have any available vaccine yet and only depends on the body's own immune system as defense and that is why public health measures against COVID-19 is very important to help reduce the spread of the disease.
When there are no public health measures in place this spike shows us that many people are getting sick all at once if that were to occur there wouldn't be enough hospital beds or mechanical ventilators for everyone who wants them and your country's healthcare system will be overwhelmed and that capacity that is already occurring in Italy for example the goal of an infectious outbreak and what this graph will hopefully show you is the significance of flattening the curve
The idea is to increase social distancing in order to slow the spread of the virus so that you don't get a huge spike in the number of people getting sick all at once there are a number of steps we can do to help flatten this curve the first step is to help protect yourself clean your hands thoroughly for at least 20 seconds especially after seeing public spaces avoid close contact with those who are sick but also reduce human to human transmission by avoiding big social gatherings in case there is somebody potentially sick there take steps to protect others by staying at home.
If you are sick isolation is recommended for at least a week and if concerned of covid-19 contact your doctor for possible diagnosis cover coughs and sneezes with tissues make sure to throw the tissue away and wash your hands wear a face mask if you are sick you do not need to wear a face mask if you are not sick unless you are caring for someone who is ill health care measures done by a doctor or the hospital are also significant
These include rapidly identifying cases with COVID-19 isolating identified cases is important and to provide optimal treatment for those patients contact tracing by identifying individuals the infected individual has been in contact with and then isolating people with suspected symptoms of covid-19 and potentially diagnosing.
New instances again and the cycle will continue the development of a vaccine for COVID-19 is an urgent public health priority you can now appreciate the importance of getting the annual vaccine against influenza for example which causes the seasonal influenza,
I hope you enjoyed this essay on covid-19 pandemic the summary I guess the take-home message is that it's important to protect yourself but also to protect others by applying those measures we just discussed stay safe.
