COVID-19 is an infectious illness caused by a type of coronavirus. There are several types of coronaviruses. Some cause mild illnesses such as a cold, while others can be more serious and affect your breathing or respiratory system. For most people, the virus won't cause serious problems. But for some people, the virus can have severe complications.
People with cancer and their families might feel especially worried about how the coronavirus virus might affect them. Cancer and its treatment can lower your ability to fight infection. So people with cancer are among those at higher risk of complications.
The coronavirus information in this section is for adults with cancer. If you are looking for coronavirus information for children with cancer, please visit the Children's Cancer and Leukaemia Group (CCLG) website.
