Those with symptoms should stay isolated for a minimum of 10 days after the first day they developed symptoms, plus another 3 days after the end of symptoms – when they are without fever and without respiratory symptoms. People without symptoms should stay isolated for a minimum of 10 days after testing positive.
Moreover, can COVID-19 be transmitted through food? There is currently no evidence that people can catch COVID-19 from food. The virus that causes COVID-19 can be killed at temperatures similar to that of other known viruses and bacteria found in food.
Additionally, 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.
Subsequently, where was COVID-19 first discovered? The first known infections from SARS-CoV-2 were discovered in Wuhan, China. The original source of viral transmission to humans remains unclear, as does whether the virus became pathogenic before or after the spillover event.
You asked, can people with mild COVID-19 symptoms recover at home? People with mild symptoms who are otherwise healthy should manage their symptoms at home. 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.
Is self-isolation recommended for those with COVID-19?
Self-isolation at home has been recommended for those diagnosed with COVID-19 and those who suspect they have been infected. Health agencies have issued detailed instructions for proper self-isolation. Many governments have mandated or recommended self-quarantine for entire populations.

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.
What can I do to prevent COVID-19 during grocery shopping?
• Clean your hands with sanitizer before entering the store.• Cover a cough or sneeze in your bent elbow or tissue.• Maintain at least a 1-metre distance from others, and if you can’t maintain this distance, wear a mask (many stores now require a mask).• Once home, wash your hands thoroughly and also after handling and storing your purchased products.
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.
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%).
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.
The most recent common ancestor (MRCA) of all coronaviruses is estimated to have existed as recently as 8000 BCE, although some models place the common ancestor as far back as 55 million years or more, implying long term coevolution with bat and avian species.
Who issued the official name of COVID-19?
The official names COVID-19 and SARS-CoV-2 were issued by the WHO on 11 February 2020.
The International Committee on Taxonomy of Viruses (ICTV) announced “severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)” as the name of the new virus on 11 February 2020. This name was chosen because the virus is genetically related to the coronavirus responsible for the SARS outbreak of 2003. While related, the two viruses are different.
What are the organs most affected by COVID‐19?
The lungs are the organs most affected by COVID‐19
How can one stay physically active during COVID-19 self-quarantine?
Walk. Even in small spaces, walking around or walking on the spot, can help you remain active. If you have a call, stand or walk around your home while you speak, instead of sitting down.
What is the difference between people who have asymptomatic or pre-symptomatic COVID-19?
Both terms refer to people who do not have symptoms. The difference is that ‘asymptomatic’ refers to people who are infected but never develop any symptoms, while ‘pre-symptomatic’ refers to infected people who have not yet developed symptoms but go on to develop symptoms later.
