Introduction

Since 11 March 2020, the Covid-19 epidemic has been reclassified as a pandemic by WHO,

An epidemic (Latin epidemia → home – the rapid development and spread of a contagious disease in a well-defined region, country or area.

A pandemic (Greek pan → all and demos → people – epidemic to several outbreaks, it extends to the entire population of a continent see from all over the world.

  1. Historical

1.1 The greatest pandemics in history

-Athse plague: 430-426 BC; 200,000 dead

-Black Plague: 1347-1352; 40 million dead

-Cholera: 1826-1919; 50 million dead

-AIDS: Since 1983; 40 million dead.

1.2 Origin of the covid-19

November/December 2019 → clustered cases of pneumonia occur in Wuhan, central China

January 9, 2020→identification of the virus responsible – new coronavirus (coronavirus – type of RNA virus responsible for respiratory and digestive infection in several mammals including humans)

1.2 Calling

1st name: nCoV
-2019

Current name: SARS-CoV-2 (SARS – Severe Acute Respiratory Syndrome; CoV – coronavirus); 2 – in reference to SARS-CoV, responsible for an epidemic from November 2002 to July 2003; WHO issued the global alert on 12 March 2003 (with more than 8,000 cases and 774 deaths, including 349 in China).

The caused disease called Covid-19 on February 11, 2020 (facilitated pronunciation; Co-corona, vi-virus, desease; 19th appearance in 2019)

1.3 Geographical distribut
ion

At the beginning: several people infected in China → epidemic

Today: 5 continents are affected (Asia, Europe, America, Africa, Oceania); nearly 180/198 countries affected →pandemia (confers map).

More than 536,454 cases worldwide and 24,114 deaths.

1.4 Epidemiological data

-the most affected countries:

USA: 85,612 cases with 1301 deaths

China: 81,340 cases with 3,292 deaths

Italy: 80,589 cases with 8215 deaths

Spain: 57,786 cases with 4,365 deaths

Germany: 47,278 cases with 281 deaths

-Cases of France: 29,155 cases with 1696 deaths

-Cases of Africa: 2,746 cases (including 152 in Burkina Faso) with 72 deaths

-Cases of Benin: 6 confirmed cases 0 deaths

Spontaneous healing without treatment in 80% of cases

Mortality: 2.5% (respiratory failure)

  1. How contamination is possible

2.1 Intermediate Host: several hypotheses including:

-The pangolin

-The bat

But researchers are still not unanimous on the issue.

2.2 Transmission mode

Inter-human transmission from an infected person to a healthy person

-direct respiratory tract (inhalation of respiratory droplets expelled through the nose or mouth of an infected person; coughing, sneezing). Rejected droplets can reach a radius of 1m and can reach 4m in a confined environment (Chinese study)

-direct contact (touching, shaking hands, hugging, etc.)

-transmission manu carried (contact of dirty hands with mouth, nose, eyes)

NB: The virus survives for about 3 days on dry inert surfaces and up to 6 days in wetlands. People of all ages and genders can become infected.

Undercooked meats and poorly washed fruit??Possible

Air transmission??Unproven

Sexual transmission??Strict → no But…

  1. Clinical events

3.1 Incubation (time between the entry of the virus from the onset of the first symptoms)

3 to 7 days

Can go up to 14 days; the extremes obtained are 0 and 24 days

3.2 Symptoms

-fever

-dry cough

-cold

-muscle pain

-sore throat

-nasal congestion

-nasal discharge

-diarrhea

-fatigue

-breathing difficulties (severe forms)

NB: sometimes asymptomatic (some infected people have no symptoms and feel good but can transmit the virus).

  1. Para Clinic

Highlighting the virus with special techniques (RT-P.C.A) on nasopharyngeal smears.

  1. Prevention

5.1 Primary prevention: all measures to prevent the virus from entering the body. They’re still called barrier gestures. These are:

Hand hygiene

-wash your hands thoroughly and regularly (every hour) with soap and water or with a hydro-alcoholic gel

-maintain a distance of at least one metre with people who cough or sneeze

-avoid touching eyes, nose and mouth

Food hygiene

Wash fruits and vegetables properly before eating them

Avoid eating raw or half-cooked meat

Respiratory hygiene

-Make sure you follow the rules of respiratory hygiene and that the people around you do the same: in case of coughing or sneezing, cover your mouth and nose with the bend of the elbow, or with a handkerchief to throw away immediately afterwards.

-wearing a surgical mask if you cough or care for a sick person (sparingly). NB: Discard single-use masks after use.

Exceptional measures

-wash surfaces or objects frequently used (mobile phones, wrists of doors, jewellery, glasses, switches, computers, faucets, etc.) several times a day

-Avoid handshakes, hugs, hugs

-Avoid large gatherings

-Avoid contact with subjects from ‘red zones’

– Respect containment measures

– Apply self-isolation when coming from a country at risk

– Learn about the evolution of the pandemic in the world to know the areas where the disease is spreading on a large scale (Italy, China, Spain, USA Germany, France…) and avoid travelling especially if you are over 60 years of age or if you have a heart or lung disease, cancer, diabetes or any other immunodeficiency pathology.

5.2 Secondary Prevention: Early Screening and Treatment

-If you experience any of the symptoms mentioned above, stay home and call green numbers 95361107; 51020000

-In case of difficulty breathing with fever, contact your doctor immediately; it could be a lung infection or any other serious condition,

-if you start to feel unwell and even if you only have mild symptoms (headache, mild fever) contact your doctor immediately

  1. treatment

-No curative treatment to date

-Symptomatic treatment and respiratory resuscitation based on severity

-encouraging results with hydroxychloroquine (study by Professor Didier Raoult)

The best treatment remains and remains prevention

Conclusion

Fake news; The second virus? → disorder and panic

Covid19 is a pandemic that in no time has slowed the global economy considerably;

-nations are blocked

– more than 3.2 billion people confined to the world and

-businesses are closed

-schools are closed

-churches are closed

-world trade is slowed down

-major events are cancelled (can festival; Tokyo Olympics etc…

Are we not moving at this pace towards an economic and financial crisis?

These moments of loneliness, fear, anguish, bereavement, stress, panic… aren’t they finally the ideal time to seriously put our lives in order and turn resolutely to God? Wouldn’t God be the real solution to this global pandemic?
