Is Asymptomatic Transmission Common For Coronavirus Disease Patients?

What should I do if I test positive for the coronavirus disease?

If people test positive, they should be isolated and the people they have been in close contact with up to 2 days before they developed symptoms should be sought out, and those people should be tested too if they show symptoms of COVID-19.WHO also advises that all confirmed cases, even mild cases, should be isolated in health facilities, to prevent transmission and provide adequate care.

But we recognize that many countries have already exceeded their capacity to care for mild cases in dedicated health facilities..

What percentage of patients with COVID-19 need to be hospitalized?

Most people (about 80%) recover from the disease without needing special treatment, and for the majority – especially for children and young adults – illness due to COVID-19 is generally minor. However, for some people it can cause serious illness.Around 1 in every 5 people who are infected with COVID-19 develop difficulty in breathing and require hospital care. People who are aged over 60 years, and people who have underlying medical conditions such as diabetes, heart disease, respiratory disease or hypertension are among those who are at greater risk.

What does it mean to be asymptomatic for COVID-19?

An asymptomatic laboratory-confirmed case is a person infected with COVID-19 who does not develop symptoms. Asymptomatic transmission refers to transmission of the virus from a person, who does not develop symptoms.

What are some ways in which the COVID-19 virus could be transmitted?

People with the virus in their noses and throats may leave infected droplets on objects and surfaces (called fomites) when they sneeze, cough on, or touch surfaces, such as tables, doorknobs and handrails. Other people may become infected by touching these objects or surfaces, then touching their eyes, noses or mouths before cleaning their hands. This is why it is essential to thoroughly clean hands regularly with soap and water or an alcohol-based hand rub product, and to clean surfaces regularly.

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.

Can coronavirus disease spread through raw food?

As a general rule, the consumption of raw or undercooked animal products should be avoided. Raw meat, raw milk or raw animal organs should be handled with care to avoid cross- contamination with uncooked foods.

Should coronavirus disease patients be isolated in hospitals?

WHO advises that all confirmed cases, even mild cases, should be isolated in health facilities, to prevent transmission and provide adequate care.But we recognize that many countries have already exceeded their capacity to care for mild cases in dedicated health facilities. In that situation, countries should prioritize older patients and those with underlying conditions.

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.

Can you get COVID-19 from touching surfaces?

People with the virus in their noses and throats may leave infected droplets on objects and surfaces (called fomites) when they sneeze, cough on, or touch surfaces, such as tables, doorknobs and handrails. Other people may become infected by touching these objects or surfaces, then touching their eyes, noses or mouths before cleaning their hands. This is why it is essential to thoroughly clean hands regularly with soap and water or an alcohol-based hand rub product, and to clean surfaces regularly.

Is headache a symptom of the coronavirus disease?

The virus can cause a range of symptoms, from ranging from mild illness to pneumonia. Symptoms of the disease are fever, cough, sore throat and headaches.

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.

Who is at a greater risk to the coronavirus disease?

Evidence to date suggests that two groups of people are at a higher risk of getting severe COVID-19 disease. These are older people (that is people over 60 years old); and those with underlying medical conditions (such as cardiovascular disease, diabetes, chronic respiratory disease, and cancer).The risk of severe disease gradually increases with age starting from around 40 years. It’s important that adults in this age range protect themselves and in turn protect others that may be more vulnerable.

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.

What is the usual body temperature in coronavirus disease patients?

The normal human body temperature remains around 36.5°C to 37°C, regardless of the external temperature or weather. The most effective way to protect yourself against the new coronavirus is by frequently cleaning your hands with alcohol-based hand rub or washing them with soap and water.

Can I breastfeed my child if I am severely ill with coronavirus disease?

If you are severely ill with COVID-19 or suffer from other complications that prevent you from caring for your infant or continuing direct breastfeeding, express milk to safely provide breastmilk to your infant.If you are too unwell to breastfeed or express breastmilk, you should explore the possibility of relactation (restarting breastfeeding after a gap), wet nursing (another woman breastfeeding or caring for your child), or using donor human milk.

Can asymptomatic patients transmit COVID-19?

See full answerAvailable evidence from contact tracing reported by countries suggests that asymptomatically infected individuals are much less likely to transmit the virus than those who develop symptoms. A subset of studies and data shared by some countries on detailed cluster investigations and contact tracing activities have reported that asymptomatically-infected individuals are much less likely to transmit the virus than those who develop symptoms.Comprehensive studies on transmission from asymptomatic patients are difficult to conduct, as they require testing of large population cohorts and more data are needed to better understand and quantified the transmissibility of SARS-CoV-2. WHO is working with countries around the world, and global researchers, to gain better evidence-based understanding of the disease as a whole, including the role of asymptomatic patients in the transmission of the virus.

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.

Can people be contagious during pre- symptomatic period of coronavirus disease?

Preliminary data suggests that people may be more contagious around the time of symptom onset as compared to later on in the disease. The incubation period for COVID-19, which is the time between exposure to the virus (becoming infected) and symptom onset, is on average 5-6 days, however can be up to 14 days.During this period, also known as the “pre- symptomatic” period, some infected persons can be contagious. Therefore, transmission from a pre-symptomatic case can occur before symptom onset.

Can I drink alcohol during the coronavirus disease pandemic?

In particular, alcohol compromises the body’s immune system and increases the risk of adverse health outcomes. Therefore, people should minimize their alcohol consumption at any time, and particularly during the COVID-19 pandemic.Alcohol is a psychoactive substance that is associated with mental disorders; people at risk or who have an alcohol-use disorder, are particularly vulnerable, especially when in self-isolation.

How many people with the coronavirus disease are asymptomatic?

For COVID-19, data to date suggest that 80% of infections are mild or asymptomatic, 15% are severe infection, requiring oxygen and 5% are critical infections, requiring ventilation.

Should asymptomatic cases of the coronavirus disease still be tested?

PCR testing of asymptomatic or mildly symptomatic contacts can be considered in the assessment of individuals who have had contact with a COVID-19 case. Screening protocols should be adapted to the local situation. The case definitions are being regularly reviewed and updated as new information becomes available.
