COVID-19Veelgestelde vraagVolledig antwoord bekijkenWhat is ‘serology’ in the context of COVID-19?‘Serology’ is the study of antibodies in blood serum. ‘Antibodies’ are part of the body’s immune response to infection. Antibodies that work against SARS-CoV-2 – the virus that causes COVID-19 – are usually detectable in the first few weeks after infection. The presence of antibodies indicates that a person was infected with SARS-CoV-2, irrespective of whether the individual had severe or mild disease, or no symptoms.‘Seroprevalence studies’ are conducted to measure the extent of infection, as measured by antibody levels, in a population under study. With any new virus, including SARS-CoV-2, initial seroprevalence in the population is assumed to be low or non-existent due to the fact that the virus has not circulated before.

Also, 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.

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
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.
Likewise, 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

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
How long have coronaviruses existed?
