title: Prevalence and characteristics of long COVID-19 in Jordan: A cross sectional survey

description: Early in the pandemic, the spread of the emerging virus SARS-CoV-2 was
 causing mild illness lasting less than two weeks for most people, with a
 small proportion of people developing serious illness or death. However,
 as the pandemic progressed, many people reported suffering from symptoms
 for weeks or months after their initial infection. Persistence of COVID-19
 symptoms beyond one month, or what is known as long COVID-19, is
 recognized as a risk of acute infection. Up to date, information on long
 COVID-19 among Jordanian patients has not been reported. Therefore, we
 sought to conduct this cross-sectional study utilizing a self-administered
 survey. The survey asks a series of questions regarding participant
 demographics, long COVID-19 symptoms, information about pre-existing
 medical history, supplements, vaccination history, and symptoms recorded
 after vaccination.  Chi square analysis was conducted on 990
 responders, and the results showed a significant correlation
 (P&lt;0.05) between long COVID-19 syndrome and age, obesity, chronic
 illness, vitamin D intake, number of times infected by COVID-19, number of
 COVID-19 symptoms and whether the infection was pre or post vaccination.
 The long-term symptoms most enriched in those with long COVID-19 were
 tinnitus (73.4%), concentration problems (68.6%) and muscle and joint ache
 (68.3%). A binomial logistic regression analysis was done to explore the
 predictors of long COVID-19 and found that age 18-45, marital status,
 vitamin D, number of COVID-19 symptoms and signs after vaccination are
 positive predictors of long COVID-19, while zinc intake is a negative
 predictor. Although further studies on long-term persistence of symptoms
 are needed, the present study provides a baseline that allows us to
 understand the frequency and nature of long COVID-19 among Jordanians.
description: # Long COVID-19 in Jordan 
 The data represent responses to a self-reporting questionnaire that was
 designed to address long COVID-19 status and factors that may associate
 with it among Jordanians. It included questions regarding COVID-19
 symptoms, pre-existing medical history, treatment and supplements,
 COVID-19 vaccination history, and symptoms recorded after vaccination. We
 adopted the definition of long COVID-19 that refers to individuals
 experiencing at least one symptom longer than four weeks. ## Description

 chronic illness (columns AF-AP), vaccine doses (column AQ, AT, AV no:0,
 Yes: 1), type of vaccine (column AR and AU, Astra:1, Pfizer:2, Sino:3,
 Sputnik: 4, None:5), time of infect (column AS, pre-vaccine: 1, post:2,
