They are usually an organism or particle that is foreign to the body, such as a bacteria, a virus or pollen. Antigens are substances that can trigger an immune response. To understand antibodies, it’s important to understand antigens. So far there is not enough information to draw any conclusions about immunity to COVID-19, even if the presence of antibodies specific to the SARS-CoV-2 virus (the virus that causes COVID-19) are detected in a blood sample. There are different types of antibodies, some are produced soon after exposure to an antigen, while others appear after a longer period of time. produced by white blood (or plasma) cells.Īntibodies help defend the body against infectious organisms such as bacteria (eg, Escherichia coli, Staphylococcus aureus) and viruses (eg, influenza A virus, hepatitis C virus) that can cause disease.small proteins that are produced by the immune system.
Anosmia is a reported symptom of COVID-19. There are many reasons why this can happen including injury to the nerve that helps you smell, injury to the nose or sinuses, or a viral infection of the respiratory system.
