Human coronaviruses are common throughout the world. Seven different coronaviruses, that scientists know of, can infect people and make them sick. Some human coronaviruses were identified many years ago and some have been identified recently.
Human coronaviruses commonly cause mild to moderate illness in people worldwide. Two newer human coronaviruses, MERS-CoV and SARS-CoV, have been known to frequently cause severe illness.
What causes coronavirus cause death ?
Infection of humans with the severe acute respiratory syndrome coronavirus (SARS-CoV) results in substantial morbidity and mortality, with death resulting primarily from respiratory failure. While the lungs are the major site of infection, the brain is also infecting in some patients.
From where coronavirus comes from ?
Coronaviruses are common in many different species of animals, including camels and bats. Rarely, these coronaviruses can evolve and infect humans and then spread between humans. Recent examples of this include SARS-CoV and MERS-CoV.
How many are infected by Coronavirus ?
Coronavirus spreads and which country are affected by Coronavirus ?
Several countries, with the largest outbreaks seen in Saudi Arabia, United Arab Emirates, and the Republic of Korea are infected by the coronavirus and now its turn china into it ( in china 3 dead and 217 infected by the coronavirus ).
China on monody reported a third death and more than 160 new cases of the coronvirus.
Symptoms of Coronavirus
The clinical spectrum of MERS-CoV infection ranges from no symptoms (asymptomatic) or mild respiratory symptoms to severe acute respiratory disease and death. A typical presentation of MERS-CoV disease is fever, cough and shortness of breath.
Pneumonia is a common finding, but not always present. Gastrointestinal symptoms, including diarrhoea, have also been reported.
Severe illness can cause respiratory failure that requires mechanical ventilation and support in an intensive care unit.
The virus appears to cause more severe disease in older people, people with weakens its immune systems, and those with chronic diseases such as renal disease, cancer, chronic lung disease, and diabetes.
Approximately 35% of patients with MERS have died, but this may be an overestimate of the true mortality rate, as mild cases of MERS may be missed by existing surveillance systems and until more is known about the disease, the case fatality rates are counted only amongst the laboratory-confirmes cases.
Prevention and treatment
No vaccine or specific treatment is currently available, however several MERS-CoV specific vaccines and treatments are in development. Treatment is supportive and based on the patient’s clinical condition.
As a general precaution, anyone visiting farms, markets, barns, or other places where dromedary camels and other animals are present should practice general hygiene measures.
Including regular hand washing before and after touching animals, and should avoid contact with sick animals.
The consumption of raw or under cooked animal products, including milk and meat, carries a high risk of infection from a variety of organisms that might cause disease in humans.
Animal products that are processed appropriately through cooking or pasteurization are safe for consumption, but should also be handled with care to avoid contamination with uncooked foods.
Camel meat and camel milk are nutritious products that can continue to be consumed after pasteurization, cooking, or heat treatments.
Until more is understanding about MERS-CoV, people with diabetes, renal failure, chronic lung disease,
As well as immunocompromised persons are consideres to be at high risk of severe disease from MERS-CoV infection.
These people should avoid contact with camels, drinking camel milk or camel urine, or eating meat that has not been properly cooking.
