What does symptomatic transmission of COVID-19 mean?

By way of definition, a symptomatic COVID-19 case is a case who has developed signs and symptoms compatible with COVID-19 virus infection.

Symptomatic transmission refers to transmission from a person while they are experiencing symptoms..

Are children at lower risk of COVID-19 than adults?

So far, data suggests that children under the age of 18 years represent about 8.5% of reported cases, with relatively few deaths compared to other age groups and usually mild disease. However, cases of critical illness have been reported. As with adults, pre-existing medical conditions have been suggested as a risk factor for severe disease and intensive care admission in children.Further studies are underway to assess the risk of infection in children and to better understand transmission in this age group.

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.

What is the incubation period of the coronavirus disease?

The incubation period of COVID-19, which is the time between exposure to the virus and symptom onset, is on average 5-6 days, but can be as long as 14 days. Thus, quarantine should be in place for 14 days from the last exposure to a confirmed case.

How does the coronavirus disease spread?

See full answerCurrent evidence suggests that COVID-19 spreads between people through direct, indirect (through contaminated objects or surfaces), or close contact with infected people via mouth and nose secretions. These include saliva, respiratory secretions or secretion droplets. These are released from the mouth or nose when an infected person coughs, sneezes, speaks or sings, for example. People who are in close contact (within 1 metre) with an infected person can catch COVID-19 when those infectious droplets get into their mouth, nose or eyes.To avoid contact with these droplets, it is important to stay at least 1 metre away from others, clean hands frequently, and cover the mouth with a tissue or bent elbow when sneezing or coughing. When physical distancing (standing one metre or more away) is not possible, wearing a fabric mask is an important measure to protect others. Cleaning hands frequently is also critical.

Are people of a particular age vulnerable to coronavirus disease?

People of all ages can be infected by the COVID-19 virus.Older people and younger people can be infected by the COVID-19 virus. Older people, and people with pre-existing medical conditions such as asthma, diabetes, and heart disease appear to be more vulnerable to becoming severely ill with the virus.

What should I do if I feel unwell during the COVID-19 pandemic?

See full answer• Know the full range of symptoms of COVID-19. The most common symptoms of COVID-19 are fever, dry cough, and tiredness. Other symptoms that are less common and may affect some patients include loss of taste or smell, aches and pains, headache, sore throat, nasal congestion, red eyes, diarrhoea, or a skin rash.• Stay home and self-isolate even if you have minor symptoms such as cough, headache, mild fever, until you recover. Call your health care provider or hotline for advice. Have someone bring you supplies. If you need to leave your house or have someone near you, wear a medical mask to avoid infecting others.• If you have a fever, cough and difficulty breathing, seek medical attention immediately. Call by telephone first, if you can and follow the directions of your local health authority.• Keep up to date on the latest information from trusted sources, such as WHO or your local and national health authorities.

Do smokers get more severe symptoms of COVID-19 if infected?

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.

Can COVID-19 be transmitted through feces or urine?

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.

Can the coronavirus disease be transmitted in hot or humid climates?

From the evidence so far, the COVID-19 virus can be transmitted in ALL AREAS, including areas with hot and humid weather. Regardless of climate, adopt protective measures if you live in, or travel to an area reporting COVID-19. The best way to protect yourself against COVID-19 is by frequently cleaning your hands. By doing this you eliminate viruses that may be on your hands and avoid infection that could occur by then touching your eyes, mouth, and nose.

Should I wear a mask while exercising during the COVID-19 pandemic?

Even when you’re in an area of COVID-19 transmission, masks should not be worn during vigorous physical activity because of the risk of reducing your breathing capacity. No matter how intensely you exercise, keep at least 1 metre away from others, and if you’re indoors, make sure there is adequate ventilation.

What does it mean to flatten the COVID-19 curve?

A flatter curve is created by a more gradual increase in the number of cases per day and a more gradual decrease. Over a long period of time the number of people infected might be around thesame, but the difference is the number of cases that occur each day.

Is a smoker at a higher risk of getting the COVID-19 virus than that a non-smoker?

See full answerAt the time of preparing this Q&A, there are no peer-reviewed studies that have evaluated the risk of SARS-CoV-2 infection associated with smoking. However, tobacco smokers (cigarettes, waterpipes, bidis, cigars, heated tobacco products) may be more vulnerable to contracting COVID-19, as the act of smoking involves contact of fingers (and possibly contaminated cigarettes) with the lips, which increases the possibility of transmission of viruses from hand to mouth. Smoking waterpipes, also known as shisha or hookah, often involves the sharing of mouth pieces and hoses, which could facilitate the transmission of the COVID-19 virus in communal and social settings.

Can drinking alcohol help in preventing COVID-19?

Alcohol does not protect against COVID-19; access should be restricted during lockdown.

Can COVID-19 be transmitted between humans and animals?

Available evidence suggests that the virus is predominantly transmitted between people through respiratory droplets and close contact, but there are also examples of transmission between humans and animals. Several animals that have been in contact with infected humans, such as minks, dogs, domestic cats, lions and tigers, have tested positive for SARS-CoV-2.

How to stay active during the COVID-19 quarantine?

See full answerFollow an online exercise class. Take advantage of the wealth of online exercise classes. Many of these are free and can be found on YouTube. If you have no experience performing these exercises, be cautious and aware of your own limitations.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. If you decide to go outside to walk or exercise, be sure to maintain at least a 1-meter distance from other people.Stand up. Reduce your sedentary time by standing up whenever possible. Ideally, aim to interrupt sitting and reclining time every 30 minutes. Consider setting up a standing desk by using a high table or stacking a pile of books or other materials, to continue working while standing. During sedentary leisure time prior

Do COVID-19 and tuberculosis spread in the same way?

See full answerTB bacilli remain suspended in the air in droplet nuclei for several hours after a TB patient coughs, sneezes, shouts, or sings, and people who inhale them can get infected. The size of these droplet nuclei is a key factor determining their infectiousness. Their concentration decreases with ventilation and exposure to direct sunlight.COVID-19 transmission has primarily been attributed to the direct breathing of droplets expelled by someone with COVID-19 (people may be infectious before clinical features become apparent). Droplets produced by coughing, sneezing, exhaling and speaking may land on objects and surfaces, and contacts can get infected with COVID-19 by touching them and then touching their eyes, nose or mouth . Handwashing, in addition to respiratory precautions, are thus important in the control of COVID-19.

How dangerous is the coronavirus disease?

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.

Can you get the coronavirus disease from people who were in hotel rooms previous to you?

Hotels and other accommodations should have procedures for cleaning, disinfecting and ventilating the room properly between every guest’s stay. These processes allow the accommodations to be used immediately afterward. If these procedures are followed, there is no need to leave the room empty between guests.

Should children wear a mask during the COVID-19 pandemic?

See full answerWHO advises that people always consult and abide by local authorities on recommended practices in their area. An international and multidisciplinary expert group brought together by WHO reviewed evidence on COVID-19 disease and transmission in children and the limited available evidence on the use of masks by children.Based on this and other factors such as childrens’ psychosocial needs and developmental milestones, WHO and UNICEF advise the following:Children aged 5 years and under should not be required to wear masks. This is based on the safety and overall interest of the child and the capacity to appropriately use a mask with minimal assistance.

Can a coronavirus be transmitted from person to person?

Yes, some coronaviruses can be transmitted from person to person, usually after close contact with an infected patient, for example, in a household workplace, or health care centre.

Can the coronavirus spread via feces?

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.

What food should you avoid during COVID-19?

• 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.

Who is at a higher risk to get infected with COVID-19?

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.​

Can smoking waterpipes spread the coronavirus disease?

Smoking waterpipes, also known as shisha or hookah, often involves the sharing of mouth pieces and hoses, which could facilitate the transmission of the COVID-19 virus in communal and social settings.

Does heat prevent COVID-19?

FACT: Exposing yourself to the sun or temperatures higher than 25°C DOES NOT protect you from COVID-19. You can catch COVID-19, no matter how sunny or hot the weather is. Countries with hot weather have reported cases of COVID-19.

Can babies get the coronavirus disease?

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.

Can the coronavirus disease spread through sewage?

There is no evidence that the COVID-19 virus has been transmitted via sewerage systems with or without wastewater treatment.

Is the coronavirus disease a pandemic?

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.

Are you immune to COVID-19 if you get it once?

Research is still ongoing into how strong that protection is and how long it lasts. WHO is also looking into whether the strength and length of immune response depends on the type of infection a person has: without symptoms (‘asymptomatic’), mild or severe. Even people without symptoms seem to develop an immune response.
