Coronavirus disease 2019 (COVID-19) is an infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The disease was first identified in December 2019 in Wuhan, the capital of China's Hubei province, and has since spread globally, resulting in the ongoing 2019–20 coronavirus pandemic.
Common symptoms include fever, cough, and shortness of breath.
Other symptoms may include fatigue, muscle pain, diarrhea, sore throat, loss of smell, and abdominal pain. The time from exposure to onset of symptoms is typically around five days, but may range from two to fourteen days. While the majority of cases result in mild symptoms, some progress to viral pneumonia and multi-organ failure.

The virus is mainly spread between people during close contact, often via small droplets produced during coughing, sneezing, or talking. While these droplets are produced when breathing out, they usually fall to the ground or onto surfaces rather than being infectious over large distances. People may also become infected by touching a contaminated surface and then their face. The virus can survive on surfaces for up to 72 hours. It is most contagious during the first three days after onset of symptoms, although spread may be possible before symptoms appear and in later stages of the disease.

The standard method of diagnosis is by real-time reverse transcription polymerase chain reaction (rRT-PCR) from a nasopharyngeal swab. Chest CT imaging may also be helpful for diagnosis in individuals where there is a high suspicion of infection based on symptoms and risk factors but is not recommended for routine screening.

Recommended measures to prevent infection include frequent hand washing, maintaining physical distance from others (especially from those with symptoms), covering coughs and sneezes with a tissue or inner elbow, and keeping unwashed hands away from the face. The use of masks is recommended for those who suspect they have the virus and their caregivers. Recommendations for mask use by the general public vary, with some authorities recommending against their use, some recommending their use, and others requiring their use. Currently, there is no vaccine or specific antiviral treatment for COVID-19. Management involves treatment of symptoms, supportive care, isolation, and experimental measures.

The World Health Organization (WHO) declared the 2019–20 coronavirus outbreak a Public Health Emergency of International Concern (PHEIC) on 30 January 2020 and a pandemic on 11 March 2020. Local transmission of the disease has been recorded in many countries across all six WHO regions.


There’s currently no vaccine to prevent coronavirus disease (COVID-19).

You can protect yourself and help prevent spreading the virus to others if you:

Do
Wash your hands regularly for 20 seconds, with soap and water or alcohol-based hand rub.
Cover your nose and mouth with a mask (FFP2), disposable tissue or flexed elbow when you cough or sneeze.
Avoid close contact (minimum 3 meters or 10 feet) with people who are unwell.
Stay home and self-isolate from others in the household if you feel unwell.

Don't
Touch your eyes, nose, or mouth if your hands are not clean.

An excellent summary of the Coronavirus Covid-19

It’s a great summary on how to avoid contagion, very informative while being clear and easy to follow.

The virus is not a living organism, but a enveloped positive-sense RNA covered with a protective layer made up of lipid (fatty matter) which, when absorbed by the ocular, nasal or buccal cells, changes its genetic code ( mutation) and turns into an attacker and multiplier cells.

Since the virus is not a living organism but a protein molecule, we cannot "kill" it properly speaking; it breaks down by itself. The duration of this disintegration depends on the temperature, the humidity level and the type of material on which it rests.

The virus is very fragile; the only thing protecting it is a thin outer layer of fat.
This is why any soap or detergent is the best remedy, because foam attacks grease (which is why you have to rub your hands as much, 20 seconds or more, in order to make a lot of foam). In
dissolving the fatty layer, we obtain that the protein molecule disperses and breaks down by itself.

The heat melts the fat, which is why it is good to use water above 25 ° C to wash your hands, clothes or anything else. In addition, hot water produces more foam and thus makes it more efficient.

- Alcohol or any other mixture containing more than 65% alcohol dissolves all fat, especially the outer lipid layer of the virus.
- Any mixture of one (1) dose of bleach for five (5) dose of water directly dissolves the protein and destroys it from the inside.
- In the absence of soap, alcohol, or chlorine, you can use hydrogen peroxide, because the peroxide dissolves the protein of the virus, but it must be used pure, which is harmful for the skin.
- No bactericide is useful. The virus is not a living organism like bacteria. You cannot kill what is not alive with antibiotics.
- Never shake clothes (on oneself or on ones that have been worn), sheets or rags. If you shake a cloth or use a feather duster, the virus molecules can float in the air for 3 hours and go and get lodged in your nose.
- When the virus is stuck on a porous surface, it is very inert and breaks down into only:
3h on a fabric for example or any other porous surface.
4h on copper (naturally antiseptic) and wood (which dries it and prevents it from coming off to
diffuse into the atmosphere).
but it can remain until:
24h on cardboard.
42h on a metal.
72h on plastic.
- The virus molecules remain very stable in the outside cold, or in the artificial cold (air conditioning in buildings or vehicles, for example…).
- Ultraviolet rays decompose the protein of the virus, whatever the surface where it is. The UV lamp, for example, is perfect for disinfecting and reusing a mask. Be careful though because
it also breaks down collagen (another protein) in the skin and can cause wrinkles and skin cancer.
- The virus cannot pass through healthy skin.
- Vinegar is useless because it does not dissolve the fatty protective layer of the virus.
- Alcoholic drinks, like vodka, have no effect (the strongest have around 40% or 50% alcohol, but the minimum required content is 65% alcohol).
- The more confined the space, the higher the concentration of the virus. The more the space is open and ventilated, the more the concentration of the virus will be reduced.

N.B .: In addition to the above indications, you must wash your hands before and after touching:
mucous membranes, food, locks, door handles, buttons and switches (light, elevators ...), telephones, remote controls, watches, computers, desks, televisions, etc ...
When you go to the toilet and / or the bathroom, it is important to hydrate your hands as they tend to dry out through repeated washing. the virus molecules can then enter micro-lesions of the skin. The thicker the moisturizer, the better.
Also make sure to keep your nails short, to prevent the virus from hiding under it.

Malaria Drug and Antibiotic Combo May Work Against COVID-19, But Experts Warn Caution and Skepticism

HU-Mediterranee Infection in Marseille, France, stated, “A treatment with the hydroxychloroquine combination (200 mg X 3 per days for 10 days) + Azithromycin (500 mg on the 1st day then 250 mg per day for 5 more days), as part of the precautions for use of this association (including an electrocardiogram on D0 and D2).
In cases of severe pneumonia, a broad-spectrum antibiotic is also used. We believe that it is not ethical that this association should not be systematically included in therapeutic trials concerning the treatment of COVID-19 infection in France.”

The French study, which is very small, “showed a significant reduction of the viral carriage” after six days of treatment and “much lower average carrying duration” compared to patients receiving other treatment. Six patients in the trial were asymptomatic and 22 had upper respiratory tract infection symptoms. Eight patients had lower respiratory tract infections. Twenty cases were treated in the study, with untreated patients acting as negative controls.
