Virus Corona Background

The virus, which has been infected in Saudi Arabia since March 2012, has never before been found in the world.

Therefore different characteristics with the SARS coronavirus infected 32 countries in the world in 2003.

The complete International Taxonomy virus Committee, The Corona Virus Study Group of the International Committee on Taxonomy of viruses on May 28, 2013, agreed to call the new coronavirus the Middle East Respiratory Syndrome-Corona Virus (MERS-CoV) both in public and scientific communication.

Symptoms of Coronavirus

The infection or COVID-19 can cause sufferers to experience flu symptoms, such as runny nose, headache, cough, sore throat, and fever; or symptoms of severe respiratory infections, such as high fever, cough with phlegm and even bleeding, shortness of breath, and chest pain.

Symptoms of Coronavirus
Symptoms of The Virus

However, in general, 3 Coronavirus Symptoms can indicate someone is infected with the virus, namely:

  • Fever
  • Cough
  • Hard to breathe

According to research, symptoms of COVID-19 appear within 2 days to 2 weeks after exposure to the virus.

When to see a doctor

Immediately see a doctor if you experience symptoms of virus infection (COVID-19), as mentioned above.

Coronavirus Doctor

Especially if the symptoms appear 2 weeks after returning from China or another positively infected country.

People suspected of being infected with the virus must be referred immediately to the nearest hospital emergency room to get proper treatment.

Causes of Coronavirus

Virus infection or COVID-19 is got by a coronavirus, which is a group of viruses that infects the respiratory system.

In most cases, it only causes mild to moderate respiratory infections, such as flu.However, this virus can also cause severe respiratory diseases, such as pneumonia, Middle-East Respiratory Syndrome (MERS), and Severe Acute Respiratory Syndrome (SARS).

Causes of The Virus

The animal is suspected to transfer this virus to a human. And later discovered that the virus also spread from human to human.

A person can get COVID-19 through a variety of ways

Accidentally inhale saliva splashes from sneezing or coughing sufferers of COVID-19.

  • Hold the mouth or nose without washing hands first, after touching an object affected by saliva splashes of COVID-19 sufferers.
  • Close contact with people with COVID-19, such as touching or shaking hands.

This virus can infect anyone, but the effect will be more dangerous or even fatal if it occurs in elderly people, pregnant women, people who are sick, or people whose immune systems are weak.

Pets such as dogs and cats can get this virus.

However, they will not pass it on to humans. Research shows that many animals are susceptible to coronavirus.

  • Birds have avian coronavirus.
  • Pigs have porcine coronavirus.
  • Cows have bovine coronavirus.
  • Whereas horses get Coronavirus Equine.

What about dogs and cats?

Coronavirus In Dogs

Dogs can be infected with this virus. This disease causes diarrhea, vomiting, and intestinal disorders in dogs.

Coronavirus In Dogs

This virus spreads through feces, especially when puppies eat feces.

Dogs can also be infected with the coronavirus, which attacks breathing, making it cough, sneeze, and mucus.

Coronavirus In Cats

Unlike dogs, the virus in cats usually makes them flu or less healthy.

However, in 5 to 10 percent of infected cats, the virus can mutate and cause Peritonitis Feline Infections, a disease that is almost always fatal.

Coronavirus In Cats

This disease usually attacks kittens. According to Dr. Niels C. Pedersen from US-Davis, viruses from various animals can exchange genes.

Some coronaviruses in cats, for example, are formed from pig and dog coronaviruses.

This coronavirus gene exchange occurs when a virus infects the same animal simultaneously.

Coronavirus Diagnosis

To determine whether the patient is infected with the Human Coronavirus, the doctor will ask about the symptoms experienced by the patient.

The doctor will also ask if the patient is traveling to the virus endemic area before symptoms appear.

Coronavirus Diagnosis

To confirm the diagnosis of COVID-19 or Coronavirus 229e, the doctor will carry out the following follow-up examinations:

  • Blood sample test
  • A throat swab test to examine sputum samples
  • Chest radiograph to detect infiltrates or fluid in the lungs

Corona Virus Treatment

About virus infection or COVID-19 can not be treated, or there is no Coronavirus Vaccine yet.

Corona Virus Treatment

But there are several steps that doctors can take to relieve the symptoms, namely:

  • Providing fever and pain relievers. However, doctors will not give aspirin to people with COVID-19 who are still young.
  • Encourage sufferers of COVID-19 to take a warm bath and use a humidifier to relieve cough and sore throat.
  • People with COVID-19 to get enough rest and not leave the house to prevent the spread of the virus.
  • Help the sufferers of COVID-19 to drink lots of water to maintain body fluid levels.

Complications of Coronavirus

Complications of Coronavirus

In severe cases, virus infection can cause the following serious complications:

  • Pneumonia
  • Secondary infection of other organs
  • Kidney failure
  • Acute cardiac injury
  • Acute respiratory distress syndrome
  • Dead

Coronavirus Prevention

Until now, there is no vaccine to prevent virus infection or COVID-19.

Therefore, the best prevention method is to avoid the factors that can cause you to be infected with this virus, namely:

Coronavirus Prevention
