This illustration, created at the Centers for Disease Control and Prevention (CDC), reveals ultrastructural morphology exhibited by coronaviruses. Note the spikes that adorn the outer surface of the virus, which impart the look of a corona surrounding the virion, when viewed electron microscopically. A novel coronavirus, named Severe Acute Respiratory Syndrome coronavirus 2 (SARS-CoV-2), was identified as the cause of an outbreak of respiratory illness first detected in Wuhan, China in 2019. The illness caused by this virus has been named coronavirus disease 2019 (COVID-19).

COVID-19 can be characterized as a pandemic. This is due to the rapid increase in the number of
cases outside China over the past 2 weeks that has affected a growing number of countries.
Although for most people COVID-19 causes only mild illness, it can make some people very ill. More
rarely, the disease can be fatal. Older people, and those with pre- existing medical conditions (such
as high blood pressure, heart problems or diabetes) appear to be more vulnerable. COVID-19 is
often more severe in people 60+yrs or with health conditions like lung or heart disease, diabetes
or conditions that affect their immune system.
SARS-CoV-2 RNA has also been detected in other biological samples, including the urine and
feces of some patients. One study found viable SARS-CoV-2 in the urine of one patient. Three
studies have cultured SARS-CoV-2 from stool specimens. To date, however, there have been
no published reports of transmission of SARS-CoV-2 through feces or urine.
There is some evidence that COVID-19 infection may lead to intestinal infection and be present
in faeces. However, to date only one study has cultured the COVID-19 virus from a single stool
specimen. There have been no reports of faecal−oral transmission of the COVID-19 virus to
date.
Viruses are named based on their genetic structure to facilitate the development of diagnostic
tests, vaccines and medicines. Virologists and the wider scientific community do this work, so
viruses are named by the International Committee on Taxonomy of Viruses (ICTV).
Swimming in a well-maintained, properly chlorinated pool is safe. However, it is advisable to
stay away from al crowded areas including crowded swimming pools. Keep 1 metre distance
from people who sneeze or cough even in a swimming area.
We know it is possible for people of any age to be infected with the virus, but so far there are
relatively few cases of COVID-19 reported among children.
• When cooking and preparing food, limit the amount of salt and high-sodium
condiments (e.g. soy sauce and fish sauce).
• Limit your daily salt intake to less than 5 g (approximately 1 teaspoon), and use
iodized salt.
• Avoid foods (e.g. snacks) that are high in salt and sugar.
• Limit your intake of soft drinks or sodas and other drinks that are high in sugar
(e.g. fruit juices, fruit juice concentrates and syrups, flavoured milks and yogurt
drinks).
• Choose fresh fruits instead of sweet snacks such as cookies, cakes and chocolate.
While there is no evidence to date about survival of the COVID-19 virus in water or sewage, the
virus is likely to become inactivated significantly faster than non-enveloped human enteric
viruses with known waterborne transmission (such as adenoviruses, norovirus, rotavirus and
hepatitis A)
Smoking any kind of tobacco reduces lung capacity and increases the risk of many respiratory
infections and can increase the severity of respiratory diseases. COVID-19 is an infectious
disease that primarily attacks the lungs. Smoking impairs lung function making it harder for the
body to fight off coronaviruses and other respiratory diseases. Available research suggests that
smokers are at higher risk of developing severe COVID-19 outcomes and death.
With Europe's highest coronavirus death toll, the United Kingdom has been under a national
shutdown since January 5. Britain's government hopes it can meet its target for rolling out
COVID-19 vaccines and be able to consider easing lockdown restrictions by March, Foreign
Minister Dominic Raab says.
