Hi everyone, welcome again to your amazing website and today we shall have another walkthrough on our most recent global attack, the novel coronavirus disease now known as the COVID-19. In our previous article about coronavirus, we promised to give you the latest updates on the developments of virologists, WHO, CDC and other great health organizations concerning this global attack and here we are fulfilling this promise.
In this article, we shall be dwelling on the COVID-19 nomenclature (naming), latest cases (worldometer), symptoms (again), mode of spreads, treatment, Mode of spread and prevention (in brief).
On the 11th of February 2020, the International Committee on Taxonomy of Viruses (ICTV) publicly named the formally novel coronavirus as “Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2)”.
This name was chosen because the virus is genetically similar to the coronavirus that causes SARS which had an outbreak in 2003. Some of these similarities include viral replication, hyperactivity of the immune system and pulmonary destruction.
Still, on 11th February 2020, the WHO in the International Classification of Diseases (ICD) declared “Coronavirus Disease 2019, (COVID-19)” as the name of this new disease. Moreover, in order to avoid panic generated by the SARS outbreak in 2003, the WHO has decided to use the name “the COVID-19 virus” while communicating with the public.

Covid-19 is a novel disease with no existing immunity nor vaccine in our various locations making the disease spread widely and rapidly. The World Health Organization has publicly declared it a pandemic.
A pandemic is a global outbreak of a disease. The WHO defines a pandemic as to when a new disease for which people lack immunity, spreads rapidly around different geographical regions beyond expectations.
Readings on 17th of March from the Worldometer presents the following global cases:
Coronavirus cases: 186,677
Total deaths: 7,471
Recovered cases: 80,338
China ranks top ( 80,881 total cases), followed by Italy (with 27,980 total confirmed cases) as Iran ranks third ( with 14,991 total confirmed cases)
For more details concerning subsequent cases and country-wise, kindly visit the worldometer link.
This is the branch of medicine that deals with the incidence, distribution and possible measures of disease and other health-related factors.
Incubation period: 2 to 14 days
Case fatality rate : ( 7,471 x100) /186677. = 4%
That is the number of deaths divided by the total number of cases expressed as a percent.
The reproductive ratio or the degree of spreadability for covid 19 is considered to be approximately 3. Meaning an infected person can contaminate 3 people closer to him/ her. This is actually a spontaneous increase and to decrease this spreadability, there is the need of self-quarantine.
Series Interval (SI): about 7.5 days.
The series interval is the gap between the onset of symptoms of patient 1 to the onset of symptoms of patient 2 as patient 2 is contaminated by patient1. The shorter the SI, the more dangerous the virus is and vice versa.
Symptoms of Covid-19.
The first thing you need to know about this virus is that, when they visit your systems, they target your lungs particularly your air sac (alveoli). And when they do so, symptoms may appear 2 to 4 days. These symptoms may vary from mild to severe cases as some individuals may recover quickly while some may result in death.
Related symptoms include:
Coughing, sore throat and fatigue.
Severe cases may lead to pneumonia and Acute Respiratory Distress Syndrome (ARDS).
Some emergency warning signs as far as this disease is concerned include:
Difficulty in breathing.
Bluish lips or face.
Continuous pain or pressure around the chest.
Inability to arouse.
The Centers for Disease Control and Prevention (CDC) recommends that when these emergency warning signs arise, kindly seek immediate medical attention.
Mode of spread.
The virus can be spread from person to person through the following ways:
- When there is close contact between a healthy individual and an infectious fellow.
- When a healthy fellow comes in contact with droplets from an infected person’s cough or sneezes.
- When a healthy person touches object surfaces contaminated with cough or sneeze from a patient and later touches his mouth or nostrils.
There is presently no medication nor vaccine for COVID-19. Treatment is through supportive care. The WHO predicts a vaccine to be fully developed within 18 months. How ever, on 9th March, the MSN news affirms some Egyptian researchers are currently working on a vaccine set to enter human-testing in 5 months’ time.
Preventing Coronavirus 2019.
1) Ways to protect yourself:
- Wash your hands as often as possible with soap and water for about 20 seconds every day.
- You may use a hand sanitizer with close to 60% alcohol to disinfect your hands in the absence of soap;
- Avoid touching your T-zone area (face, eyes, and nose) especially with unclean hands.
- Do your best to avoid massive crowds where some infected individuals may be among.
- Don’t go closer or try to help those who are sick. If you find a patient helpless, kindly call the medical authorities or health care workers for assistance.
- Don’t shake hands with people.
- Avoid touching objects with your hands.
- Properly clean and disinfect high touch objects like your phones, hand doors, keyboards, etc.
- Keep a distance of about 2 meters from an infected person.
The CDC has highly requested that organizers of events should cancel or postpone events that would permit the gatherings of 50 or more people. This practice should be implemented within 2 months. However, schools, colleges, and businesses are exempted from this clause. Notwithstanding, for the sake of severity of this latest pandemic it is out of good faith that all institutions should avoid the calling of crowds due to the high Ro (spreadability) value of Covid-19.
2) Ways to protect others:
- If you are infected by this virus, you are requested to stay home. However, your movement should be restricted only to the hospital for medical attention. It is also advisable to call your health care provider in advance before visiting the hospital.
- Avoid public areas and gatherings if you are ill. Also, stay home and don’t go to work nor school nor to the shop.
- Patients at home are requested to stay separately from family members.
- Patients should stop touching household equipment and utensils.
- Infected people when going to the hospital are requested to put on a mask.
- Sick or healthy, use a tissue during sneezing or coughing and this should be properly disposed of as you effectively wash your hands after this exercise.

Those Prone to COVID-19.
Those who are at higher risk of this disease are people above 60 years old and those who have a chronic disease. These individuals are requested to self-quarantine.
- Rule out Influenza A/B by carrying out the Nasopharyngeal swab test.
- The Reverse Transcription Polymerase Chain Reaction (RT-PCR) can be carried out. This test takes a lot of time and has a sensitivity of about 30 – 70%. This implies 3 – 7 out of 10 patients who actually have the virus or disease will have a negative PCR result.
- The most popular test is the Chest CT test. It has an initial sensitivity of about 95%, meaning less than 1 of every 20 cases may be missed out who may go home and spread the disease.
