How long does the virus that causes COVID-19 last on surfaces?

Recent research evaluated the survival of the COVID-19 virus on different surfaces and reported that the virus can remain viable for up to 72 hours on plastic and stainless steel, up to four hours on copper, and up to 24 hours on cardboard.

Can the coronavirus disease be transmitted through water?

Drinking water is not transmitting COVID-19. And, if you swim in a swimming pool or in a pond, you cannot get COVID-19 through water. But what can happen, if you go to a swimming pool, which is crowded and if you are close to other the people and if someone is infected, then you can be of course affected.

In what conditions does COVID-19 survive the longest?

Coronaviruses die very quickly when exposed to the UV light in sunlight. Like other enveloped viruses, SARS-CoV-2 survives longest when the temperature is at room temperature or lower, and when the relative humidity is low (<50%).

Can you get COVID-19 from faeces?

The risk of catching the COVID-19 virus from the faeces of an infected person appears to be low. There is some evidence that the COVID-19 virus may lead to intestinal infection and be present in faeces.

How long can the virus that causes COVID-19 survive on surfaces after being expelled from the body?

After being expelled from the body, coronaviruses can survive on surfaces for hours to days. If a person touches the dirty surface, they may deposit the virus at the eyes, nose, or mouth where it can enter the body and cause infection.

How should I wash fruits and vegetables in the time of COVID-19?

Wash fruit and vegetables the same way you would in any other circumstance. Before handling them, wash your hands with soap and water. Then wash fruits and vegetables thoroughly with clean water, especially if you eat them raw.

How does COVID-19 spread?

• Current evidence suggests that the virus spreads mainly between people who are in close contact with each other, typically within 1 metre (short-range). A person can be infected when aerosols or droplets containing the virus are inhaled or come directly into contact with the eyes, nose, or mouth.

How long does it take for symptoms of the coronavirus disease to appear?

On average it takes 5–6 days from when someone is infected with the virus for symptoms to show, however it can take up to 14 days.

Do smokers suffer from worse COVID-19 symptoms?

Early research indicates that, compared to non-smokers, having a history of smoking may substantially increase the chance of adverse health outcomes for COVID-19 patients, including being admitted to intensive care, requiring mechanical ventilation and suffering severe health consequences.

What are the organs most affected by COVID‐19?

The lungs are the organs most affected by COVID‐19

Is sugar ok to consume during isolation?

Limit your sugar intake WHO recommends that ideally less than 5% of total energy intake for adults should come from free sugars (about 6 teaspoons). If you crave something sweet, fresh fruit should always be the priority.

Can we spray disinfectants on streets and sidewalks during the COVID-19 pandemic?

Streets and sidewalks are not considered as routes of infection for COVID-19. Spraying disinfectants, even outdoors, can be noxious for people's health and cause eye, respiratory or skin irritation or damage.

Does WHO recommend the use of masks with exhalation valves to prevent transmission of COVID-19?

No, WHO does not advise using masks or respirators with exhalation valves. These masks are intended for industrial workers to prevent dust and particles from being breathed in as the valve closes on inhale. However, the valve opens on exhale, making it easier to breathe but also allowing any virus to pass through the valve opening. This makes the mask ineffective at preventing the spread of COVID-19 or any other respiratory virus.

What is the best household disinfectant for surfaces during COVID-19?

Regular household cleaning and disinfection products will effectively eliminate the virus from household surfaces. For cleaning and disinfecting households with suspected or confirmed COVID19, surface virucidal disinfectants, such as 0.05% sodium hypochlorite (NaClO) and products based on ethanol (at least 70%), should be used.
