How long does the Coronavirus survive inside and outside human body and pets ?


How long does coronavirus survive outside the body?

The new strain of coronavirus known as COVID-19 spreads rapidly around the world. According to the disease experts, the outbreak of the virus primarily spreads from one person to another through sneezing or coughing.

According to the Center for Disease Control (CDC), the transmission is also possible if the person touches the surface or object that has coronavirus on it and then touches the eyes, nose, and mouth.

How long does the COVID virus survive in the saliva?

It is not really clear as to how long coronavirus 2019 stays in the saliva, but it tends to behave like other coronaviruses. As a safety precaution, kissing is highly discouraged in a social gathering, and even in people who have an active infection such as cough and colds. Make sure that the saliva will not be in contact with you. In the case of splashes of saliva, you have to thoroughly clean your body with soap and water or with alcohol.

How long does the COVID-19 virus test take to report or results?

Those in the United States can be tested right away. The health worker will use a long Q-tip to take a swab at the back of the throat and sends the sample for testing. For people living in countries where the antibody test has already developed, blood is drawn.

The throat swab is sent for polymerase chain reaction testing (PCR) while the blood sample is mined for antibody specific to COVID-19. The tests usually take a few hours to run and the results could be available in a day. If the rapid form of PCR and antibody has been created, the results could be immediately drawn.

How long does the COVID-19 virus last in cats and dogs?

The general public shouldn’t be worried that their pets might catch coronavirus 2019. There’s a recent case wherein a Pomeranian dog test weak positive for coronavirus.

However, it is unsure if the dog catches it directed from an infected person or from a contaminated surface. However, later study suggested that the dog has a low level of infection and more of a case of human to animal transmission.

How long does coronavirus live on surfaces?

Coronavirus can remain infectious on surfaces for up to nine days at room temperature. Fortunately, they can be inactivated using common home disinfectants. On copper and steel, the virus can survive for up to two hours. However, the virus survives longer in cardboard and plastic materials.

How long does coronavirus remain in the body?

Viruses persist at a low level in the body even after recovering from illness. This is true in the case of ebola and Zika virus that stick for months after the patients recover. Four patients from Wuhan, China were tested to look for genetic fragments of the virus in the body. At that time, they were taking Tamiflu, which could have pushed the viral copies down to a minute number.

The test was not sensitive enough to detect the virus. There’s a possibility that the virus may replicate again but at a low level. However, the patient remains asymptomatic as the number of viruses is not enough to cause tissue damage. They remain to be a carrier of the virus but not able to transmit outside of the close contact.
