SARS-CoV-2 tests can performed on a sample—collected, for example, via a nasopharyngeal, oropharyngeal, nasal midturbinate, or anterior nares swab—using a reverse-transcription polymerase chain reaction (RT-PCR) assay. Unfortunately, current COVID-19 testing is showing variable rates of false negatives.9 jun. 2020
How can serology test be helpful in understanding the COVID-19 pandemic?
COVID-19Veelgestelde vraagVolledig antwoord bekijkenHow can serology test be helpful in understanding the COVID-19 pandemic?Serologic tests measure the antibody response in an individual. Antibodies to COVID-19 are produced over days to weeks after infection with the virus. The presence of antibodies indicates that a person was infected with the COVID-19 virus, irrespective of whether the individual had severe or mild disease, or even asymptomatic infection. Surveillance of antibody seropositivity in a population can allow inferences to be made about the extent of infection and about the cumulative incidence of infection in the population. The use of serology in epidemiology and public health research enables understanding of:• the occurrence of infection among different populations;• how many people have mild or asymptomatic infection, and who may not have been identified by routine disease surveillance;• the proportion of fatal infections among those infected;• the proportion of the population who may be protected against infection in the future
Also, Has the coronavirus disease been detected in blood and stool?
Additional clinical specimens may be collected as COVID-19 virus has been detected in blood and stool, as had the coronaviruses responsible for SARS and MERS (14,16,19-21). The duration and frequency of shedding of COVID-19 virus in stool and potentially in urine is unknown.2 mrt. 2020

Can the coronavirus disease spread through feces?
COVID-19Veelgestelde vraagCan the coronavirus disease spread through feces?The risk of catching the COVID-19 virus from the faeces of an infected person appears to be low. There is some evidence that the COVID-19 virus may lead to intestinal infection and be present in faeces. Approximately 2−10% of cases of confirmed COVID-19 disease presented with diarrhoea (2−4), and two studies detected COVID-19 viral RNA fragments in the faecal matter of COVID-19 patients (5,6).However, to date only one study has cultured the COVID-19 virus from a single stool specimen (7). There have been no reports of faecal−oral transmission of the COVID-19 virus.3 mrt. 2020
Does COVID-19 infections have long term effects?
COVID-19Veelgestelde vraagDoes COVID-19 infections have long term effects?Most people recover from the acute phase of the disease. However, some people continue to experience a range of effects for months after recovery—named long COVID—and damage to organs has been observed. Multi-year studies are underway to further investigate the long-term effects of the disease.
Does the presence of antibodies mean that a person is COVID-19 immune?
COVID-19Veelgestelde vraagDoes the presence of antibodies mean that a person is COVID-19 immune?There are many studies underway to better understand the antibody response following infection to SARS-CoV-2. Several studies to date show that most people who have been infected with SARS-CoV-2 develop antibodies specific to this virus. However, the levels of these antibodies can vary.
Can I get COVID-19 from eating fresh food?
Use proper food safety practices when handling food and before, during and after preparing or eating food. Currently, there is no evidence that the virus that causes COVID-19 spreads to people through food.31 dec. 2020
Is the coronavirus disease transmitted by direct contact?
COVID-19Veelgestelde vraagIs the coronavirus disease transmitted by direct contact?The virus is transmitted through direct contact with respiratory droplets of an infected person (generated through coughing and sneezing). Individuals can also be infected from and touching surfaces contaminated with the virus and touching their face (e.g., eyes, nose, mouth).
How long does the virus that causes COVID-19 last on surfaces?
COVID-19Veelgestelde vraagHow 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.7 apr. 2020
Can the COVID-19 survive in drinking water?
COVID-19Veelgestelde vraagCan the COVID-19 survive in drinking water?Currently, there is no evidence about the survival of the COVID-19 virus in drinking-water or sewage.19 mrt. 2020
Which organs are most affected by COVID-19?
COVID-19Veelgestelde vraagWhich organs are most affected by COVID-19?The lungs are the organs most affected by COVID-19 because the virus accesses host cells via the receptor for the enzyme angiotensin-converting enzyme 2 (ACE2), which is most abundant on the surface of type II alveolar cells of the lungs.
What are some differences between COVID-19 and influenza?
COVID-19Veelgestelde vraagVolledig antwoord bekijkenWhat are some differences between COVID-19 and influenza?The speed of transmission is an important point of difference between the two viruses. Influenza has a shorter median incubation period (the time from infection to appearance of symptoms) and a shorter serial interval (the time between successive cases) than COVID-19 virus. The serial interval for COVID-19 virus is estimated to be 5-6 days, while for influenza virus, the serial interval is 3 days. This means that influenza can spread faster than COVID-19. Further, transmission in the first 3-5 days of illness, or potentially pre-symptomatic transmission –transmission of the virus before the appearance of symptoms – is a major driver of transmission for influenza. In contrast, while we are learning that there are people who can shed COVID-19 virus 24-48 hours prior to symptom onset, at present, this does not appear to be a major driver of transmission.17 mrt. 2020
Why do some people get side effects from Covid vaccine and others don t?
COVID-19Veelgestelde vraagWhy do some people get side effects from Covid vaccine and others don t?This rapid-response step of your immune system tends to wane with age, one reason younger people report side effects more often than older adults. Also, some vaccines simply elicit more reactions than others. That said, everyone reacts differently.10 jun. 2021
How long have coronaviruses existed?
COVID-19Veelgestelde vraagHow long have coronaviruses existed?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.
