Coronavirus: causes, symptoms, treatment and diagnosis

The kidneys are responsible for cleaning the blood, removing waste products and acids as well as extra fluid. Where some people suffer mild flu symptoms, others have contracted viral , which is resistant to antibiotics and therefore difficult to treat. Recent studies in experimentally infected animal strongly suggest a crucial role for virus-induced immunopathological events in causing fatal pneumonia after hCoV infections. So are children under the age of 5 and seniors who are at least 65. A virus can trigger the disease. Any fever in an infant or toddler, however, should be taken seriously.

Why are some viruses more dangerous than others? Over the last 70 years, scientists have found that coronaviruses can infect mice, rats, dogs, cats, , horses, pigs, and cattle. Unfortunately, most of these processes are also bad for the host. Research in Emerging Infectious Diseases confirms that many African bats are also reservoirs of the incredibly dangerous Ebola virus. Although the virus can have severe effects on people now, experts say that this can diminish over time as our immune systems adapt. In the years since these viruses first emerged as a severe global health threat, researchers have been studying their molecular biology in an effort to answer such questions. In general, adults need not be concerned about a fever unless their temperature , according to the Mayo Clinic.

According to Matthew Frieman, an associate professor of microbiology and immunology at the University of Maryland, coronaviruses are a family of viruses that usually cause the common cold. These viruses are typically responsible for common colds more than serious diseases. Shortness of breath A variety of lung conditions can cause shortness of breath, including pneumonia, asthma and chronic obstructive pulmonary disease. The low pathogenic CoVs infect the upper respiratory tract and cause mild, cold-like respiratory illness. In general, quarantines are used to keep an already-sick person from spreading to others.

The American man started experiencing respiratory symptoms after a trip to China near where the outbreak began. However, while some viruses are highly contagious, it is less clear how rapidly coronaviruses will spread. This new strain in China, however, appears to have the fever as the most prominent symptom. This is because coronavirus antibodies do not last for a long time. Of these, 774 infections were fatal. Scientific American maintains a strict policy of editorial independence in reporting developments in science to our readers. Nanda says how long these individuals are held in quarantine depends on how long the incubation period is of the bacteria or virus doctors want to contain — essentially, how long experts think it would take for a potentially infected person to show symptoms.

People who are older or have existing medical conditions, such as heart disease, may be at higher risk of serious illness. Also, the antibodies for one strain of coronavirus may be ineffective against another one. So far, Frieman says, it has been reported that this new coronavirus causes a spectrum of respiratory symptoms, from mild cold-like symptoms to severe pneumonia and even death in several patients so far. Human coronavirus is a type of zoonotic disease in which the infection spreads from animals to humans. But there were no bats being sold at the animal market in Wuhan, China, where the current outbreak is thought to have begun, suggesting an intermediate host species was likely involved. With the sequencing of different strains, you can assess the population and transmission dynamics of what strain came from where, because the sequence ties the virus to its origin.

The virus binding to a receptor is only the first step in the cell entry process. The Wuhan coronavirus appears to cause pneumonia in two ways: when the virus takes hold in the lungs, and through secondary bacterial infections, however, the first way appears to be more common. This is similar to what is seen with other respiratory illnesses, such as influenza. To prevent transmission, people should stay at home and rest while symptoms are active. A coronavirus particle consists of four structural proteins: the nucleocapsid, envelope, membrane and spike. This includes coughing, a runny nose, a sore throat and sometimes a fever,' explains Dr Abbs. During November 2002, the virus started in the Guangdong Province in southern China, eventually reaching Hong Kong.

Damage results from either viruses taking over the cell completely and causing it to die, or immune cells recognising the viral infection and mounting a defence, triggering cell death. Some coughing is normal, but if a cough lasts for weeks, , the Mayo Clinic advises. This equates to a mortality rate of 9.
