The novel coronavirus, or COVID-19, is spreading in countries across the word, including in the East African region.

Many Sudanese and South Sudanese do not know how contagious the new coronavirus is.

This piece aims at explaining World Health Organization (WHO) guides on how to protect yourself and others from the virus.

In our previous section we explained the most effective ways to protect yourself and others against COVID-19. Today we look at the section which is the incubation period for COVID-19 and how long does the virus survive on surfaces.

How long is the incubation period for COVID-19?

The “incubation period” means the time between catching the virus and beginning to have symptoms of the disease. Most estimates of the incubation period for COVID-19 range from 1-14 days, most commonly around five days. These estimates will be updated as more data become available.

Can humans become infected with the COVID-19 from an animal source?

Coronaviruses are a large family of viruses that are common in animals. Occasionally, people get infected with these viruses which may then spread to other people. For example, SARS-CoV was associated with civet cats and MERS-CoV is transmitted by dromedary camels. Possible animal sources of COVID-19 have not yet been confirmed.  

To protect yourself, such as when visiting live animal markets, avoid direct contact with animals and surfaces in contact with animals. Ensure good food safety practices at all times. Handle raw meat, milk or animal organs with care to avoid contamination of uncooked foods and avoid consuming raw or undercooked animal products.

Can I catch COVID-19 from my pet?

While there has been one instance of a dog being infected to date, there is no evidence that a dog, cat or any pet can transmit COVID-19. COVID-19 is mainly spread through droplets produced when an infected person coughs, sneezes, or speaks. To protect yourself, clean your hands frequently and thoroughly. 

WHO says it continues to monitor the latest research on this and other COVID-19 topics and will update as new findings are available.

How long does the virus survive on surfaces?

It is not certain how long the virus that causes COVID-19 survives on surfaces, but it seems to behave like other coronaviruses. Studies suggest that coronaviruses (including preliminary information on the COVID-19 virus) may persist on surfaces for a few hours or up to several days. This may vary under different conditions (e.g. type of surface, temperature or humidity of the environment).

If you think a surface may be infected, clean it with simple disinfectant to kill the virus and protect yourself and others. Clean your hands with an alcohol-based hand rub or wash them with soap and water. Avoid touching your eyes, mouth, or nose.

The next section is about the likelihood of an infected person contaminating commercial goods and what to do in case you have fever, cough and difficulty breathing. Radio Tamazuj will bring you more information about this part tomorrow.
