Awareness of COVID-19 Symptoms, Risk Factors, and Vaccinations in Patients with Multiple Sclerosis.

Multiple Sclerosis (MS) is the most common chronic autoimmune disease of the central nervous system, affecting around 2.8 million people worldwide. Patients' knowledge about COVID-19 infection, and their proper protective actions, may reduce the risk of infection. The aim of this study was to assess the knowledge of patients with MS about SARS-CoV-2, COVID-19 illness, the relationship between MS and COVID-19, willingness to be vaccinated, and the impact of the pandemic on MS care. An original, anonymous, 35-items, self-reported questionnaire was used in both web-based and on-site survey formats. Two-hundred and forty-eight questionnaires were analyzed (mean age 40.8 ± 10.6 years, 77.8% women). Participants reported the use of multiple sources of information, and the most common were websites (77.8%) and television (59.3%). The majority of participants knew the correct symptoms of COVID-19 or transmission routes (94.4%), and accepted the pandemic's restrictions (96.8%). A total of 93.2% considered SARS-CoV-2 as highly infectious, and 69% thought they were at higher risk of being infected with SARS-CoV-2, mainly because of immunodeficiency (82.7%). Although most of them were afraid of COVID-19 (69.0%), only two-thirds wanted to be vaccinated. Patients who were afraid of COVID-19 had a 3.5-times higher chance to declare willingness for vaccination. A total of 29.8% patients claimed that the COVID-19 pandemic limited access to the healthcare system. This study shows that Polish patients with MS represent a good level of knowledge about COVID-19 disease, and acceptance for public rules, but their willingness for vaccinations is not sufficient. Country-wide educational campaigns should be conducted, particularly on the internet and TV. Restrictions in healthcare facilities should be balanced to secure access for patients with MS.
