Three common clusters of symptoms have been identified: one respiratory symptom cluster with cough, sputum, shortness of breath, and fever; a musculoskeletal symptom cluster with muscle and joint pain, headache, and fatigue; a cluster of digestive symptoms with abdominal pain, vomiting, and diarrhea.
What are some symptoms of COVID-19?
Three common clusters of symptoms have been identified: one respiratory symptom cluster with cough, sputum, shortness of breath, and fever; a musculoskeletal symptom cluster with muscle and joint pain, headache, and fatigue; a cluster of digestive symptoms with abdominal pain, vomiting, and diarrhea.
Who are at higher risk of developing serious illness from COVID-19?
Older people, and those with underlying medical problems like cardiovascular disease, diabetes, chronic respiratory disease, and cancer are more likely to develop serious illness.
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.
What are coronavirus diseases?
Coronaviruses are a group of related viruses that cause diseases in mammals and birds. In humans, coronaviruses cause respiratory tract infections that can range from mild to lethal.
Which types of settings does COVID-19 spread more easily?
The “Three C’s” are a useful way to think about this. They describe settings where transmission of the COVID-19 virus spreads more easily:• Crowded places;• Close-contact settings, especially where people have conversations very near each other;• Confined and enclosed spaces with poor ventilation.
Can the coronavirus survive on surfaces?
It is not certain how long the virus that causes COVID-19 survives on surfaces, but it seems likely to behave like other coronaviruses. A recent review of the survival of human coronaviruses on surfaces found large variability, ranging from 2 hours to 9 days (11).The survival time depends on a number of factors, including the type of surface, temperature, relative humidity and specific strain of the virus.
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.
Are smokers more likely to develop severe disease with COVID-19?
How could smoking affect COVID-19?
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 diseases.
Can the coronavirus disease be transmitted through the consumption of cooked foods, including animal products?
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.
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.
How does COVID-19 spread?
See full answerSARS-CoV-2 is mainly spread via respiratory droplets including aerosols from an infected person who sneezes, coughs, speaks, sings or breathes in close proximity to other people. Droplets including aerosols can be inhaled or deposited in the nose and mouth or on the eyes.More rarely, infection may be due to contact with surfaces contaminated with droplets.The virus can survive on different surfaces for a few hours (copper, cardboard) up to a number of days (plastic and stainless steel). However, the amount of viable virus declines over time and it is rarely present on surfaces in sufficient quantities to cause infection. Infection may occur when a person touches their nose, mouth or eyes with their hands either contaminated by fluids containing the virus or indirectly by having touched surfaces contaminated with the virus.
What are the known coronaviruses that can infect people?
Human coronaviruses are capable of causing illnesses ranging from the common cold to more severe diseases such as Middle East respiratory syndrome (MERS, fatality rate ~34%). SARS-CoV-2 is the seventh known coronavirus to infect people, after 229E, NL63, OC43, HKU1, MERS-CoV, and the original SARS-CoV.
Where were first COVID-19 infections 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.
Where was the first case of the coronavirus disease observed?

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.
How is the COVID-19 disease transmitted?
COVID-19 transmits when people breathe in air contaminated by droplets and small airborne particles containing the virus. The risk of breathing these in is highest when people are in close proximity, but they can be inhaled over longer distances, particularly indoors. Transmission can also occur if splashed or sprayed with contaminated fluids in the eyes, nose or mouth, and, rarely, via contaminated surfaces.
Can I get COVID-19 while swimming?
The COVID-19 virus does not transmit through water while swimming. However, the virus spreads between people when someone has close contact with an infected person. WHAT YOU CAN DO:Avoid crowds and maintain at least a 1-metre distance from others, even when you are swimming or at swimming areas. Wear a mask when you’re not in the water and you can’t stay distant. Clean your hands frequently, cover a cough or sneeze with a tissue or bent elbow, and stay home if you’re unwell.
What areas, in non-healthcare settings, should be prioritized for disinfection during the COVID-19 pandemic?
High-touch surfaces in these non-health care settings should be identified for priority disinfection such as door and window handles, kitchen and food preparation areas, counter tops, bathroom surfaces, toilets and taps, touchscreen personal devices, personal computer keyboards, and work surfaces.
What does ‘local transmission’ mean during the coronavirus disease outbreak?
– Local transmission indicates locations where the source of infection is within the reporting location.
