Coronavirus (2019-nCoV) is the name given to viruses from the coronavirus family. In humans, the pathogenic germ can cause simple diseases like the common cold, unable to Focus but can also be responsible for serious epidemics, as has been the case since the end of 2019 with the coronavirus from China, 2019-nCoV. Definition and explanations.
The death toll continues to climb in China.
New cases surged by double-digit percentages in 11 days.
More people have now died in this epidemic than the SARS pandemic of 2003. At least 25 countries and territories around the world have been reporting more cases.
China’s National Health Commission announced the total number of deaths reached at least 2,700 and 80,000+ people have tested positive for the virus. It was an increase of at least 65 deaths and more than 3,800 new infections from the previous day and was the most of either figure recorded in a single day.
All the deaths reported on Tuesday from Hubei province, where the outbreak is the most serious. China has completed building a new hospital in Wuhan. The first batch of virus patients arrived at the Huoshenshan hospital on Tuesday.
For the past week, Wuhan has been building more two hospitals with thousands of beds for confirmed patients to help ease the shortage of beds in the city. The second hospital is set to be completed by Wednesday this week. Outside of China, some 220+ confirmed cases of the C-virus have been reported in at least 25 countries & territories.
Japan has the highest number of confirmed cases outside of China with 35 cases
Japanese authorities announced on Wednesday that three Japanese nationals and seven other people who were on a cruise ship tested positive for the virus. The remaining three thousand plus passengers, including 9 South Koreans, have been transferred to hospitals in Japan where they will be quarantined.
Thailand has 25 confirmed patients, followed by Singapore with 24.
South Korea has confirmed three additional cases on Wednesday raising the figure to 19. Ten cases each have been confirmed in Malaysia, Macao, and Vietnam. And there are six in France, 5 in the United Arab Emirates, and three in India. The United States saw 11 confirmed cases after two more cases have been reported from California on Monday.
Meanwhile, two deaths have also been reported outside of China, one from Hong Kong and the Philippines. Hong Kong saw 18 confirmed cases, while the Philippines has 3 cases.
- Coronavirus: definition
- Are they dangerous to humans?
- Epidemics linked to coronaviruses
Coronaviruses (Cpv) are viruses from the coronavirus family, the particularity of which is that they have a very long RNA genome (ribonucleic acid allows the transport of the genetic message and protein synthesis). These germs are surrounded by a crown-shaped protein capsule, hence their name.
Are they dangerous to humans?
Coronaviruses can be responsible for several diseases in several mammals. In humans, these infections can be:
- Persons responsible for benign pathologies such as a cold or influenza-like illness;
- Responsible for respiratory complications such as pneumonia in immunocompromised patients or infants;
- Responsible for the severe respiratory syndrome, leading to epidemics.
- These viruses are transmitted by;
- Airway ;
- In contact with secretion;
- In contact with contaminated objects.
The incubation period, when the first symptoms appear, is 3 to 6 days. And in general, treatment focuses on the symptoms.
Epidemics linked to coronaviruses
While in the majority of cases, coronaviruses cause asymptomatic or mild infections, they can also cause epidemics. This was the case in 2002 & 2003 with SARS-CoV linked to the severe acute respiratory syndrome. Part of Guangdong province in southeast China, the infection has affected around 30 countries around the world.
It was symptomless in some cases, or a fever, dry cough, muscle pain, headache, severe fatigue. A total of 774 deaths have been recorded. Great that the global alert generated by the World Health Organization (WHO), the epidemic was able to be controlled.
In 2012, the country of Saudi Arabia was also affected by a coronavirus, called MERS-CoV (Middle East respiratory syndrome coronavirus). To date, he is responsible for the death of 567 deaths in 26 countries (only two cases diagnosed in France in 2013).
MERS-CoV has the same symptoms as its predecessor, SARS-CoV. Both coronaviruses have the bat as their reservoir, but a second host has caused the transmission to humans: civet for SARS-CoV and dromedary for MERS-CoV.
At the end of 2019, a new coronavirus was detected in China and named 2019-nCoV. The first cases of lung infection are noticed in Wuhan, in the east of the country. Symptoms are also fever, dry cough, shortness of breath, even acute respiratory distress, multi-visceral failure or acute renal failure in some people at higher risk. With nearly 24,000 cases recorded worldwide by the WHO.
