Benghazi experienced a Coronaviruses pandemic like every other big city in the world. In fact, according to Benghazi’s medical anti-coronaviruses committee, on the seventh of April 2020, documented it was the first case of COVID-19, who was a male aged 55 years old, had lung issues, and arrived in Benghazi from Türkiye via Tunisia.

The severe acute respiratory syndrome coronavirus (SARS-CoV-2), which was originally identified in November 2002, and the Middle East respiratory syndrome coronavirus (MERS-CoV), which was first revealed in September 2012, were both caused by Coronaviruses [1] [2] .

Infection occurs by tremendous droplets produced by symptomatic patients coughing and sneezing, but it can also come from asymptomatic individuals and begin before the onset of symptoms [3] . Such diseased droplets can deposit on surfaces and propagate 1 - 2 meters. The virus can survive on surfaces for days, but simple disinfectants like hydrogen peroxide and sodium hypochlorite kill them in just a minute [4] . Therefore, respiratory droplet and contact transmission are the main ways that SARS-CoV-2 spreads from person to person. The virus can be spread by infected people both throughout the incubation period and the recovery period [5] .

The majority of SARS-CoV-2 infected recipients are still asymptomatic. However, in symptomatic patients, the disease’s clinical manifestations typically take from two to five days or so to manifest themselves. With a median of 14 days, the time from the onset of COVID-19 symptoms to mortality ranged from 6 to 41 days [6] [7] . Fever, cough, and exhaustion are just a few of the many symptoms of COVID-19 that can differ from person to person [7] [8] . Other symptoms include sputum production, tachycardia, headache, hemoptysis, diarrhea, dyspnea, lymphopenia, and depression.

The progression of COVID-19 into a severe and critical stage has been linked to elderly subjects, males, underlying comorbidities like hypertension, diabetes, obesity, chronic lung diseases, heart diseases, liver diseases, kidney diseases, tumors, clinically apparent immunodeficiency, and pregnancy [9] .

Several studies have shown a wide range of symptoms associated with post-acute COVID-19 syndrome, according to WHO, it is a disorder that typically requires at least 2 months to manifest before being diagnosed, occurs 3 months after the initiation of COVID-19, and cannot be explained by another illness. The underlying disease’s symptoms may return or they may differ from those felt during an acute COVID-19 episode. Over time, symptoms may also shift or come back. Patients who initially only experienced mild to moderate acute symptoms and did not require hospitalization still experience long-term problems. Fatigue and dyspnea are two of these symptoms. Other less common symptoms include mental and cognitive impairments, headaches, myalgia, joint and chest pains, abnormalities of taste and smell, coughing, hair loss, sleeplessness, wheezing, rhinorrhea, sputum, cardiac and gastrointestinal problems. After being released from the hospital or when the symptoms first appear, they may last up to six months. Long COVID has also been linked to less common symptoms including cold, flushing, earache, and visual impairments. These symptoms are comparable to those of people with prior viral illness epidemics (SARS and MERS) [10] [11] [12] .

The purpose of this research was to investigate and get an understanding of the post-coronavirus syndrome (COVID-19) symptoms among Benghazi’s city survivors. Factors that aggravate or tag signs and symptoms of post-COVID syndrome (PCS) also evaluate the effective treatment between those patients.

In across-sectional epidemiological study of 325 Benghazi’s residents, Regardless of their gender or age, these patients had been diagnosed with Coronavirus at least two months, prior were asked to complete a specially created questionnaire regarding their current health status and any lingering symptoms, they had after acquiring the virus. More than 200 others also took part in the study by using a special web link and responding to the same survey. Those individuals who completed the survey were asked to indicate their acceptance to participate in the study at the outset of the questionnaire. 24 subjects out of a total of 325 were excluded due to their responses were insufficient. This research was conducted during the period of 10 months from December 2021 to September 2022.

Analogous to the questionnaire, it has eight components, as shown in Table 1.

In the current study, we focused on the prevalence as well as characteristics of the Post-COVID Syndrome(PCS) in a population consisting of 301 COVID-19 convalescent patients, where, COVID-19 is a new disease with a narrow range of information on the PCS (Galal, et al., 2021) [13] . Based on the current findings, there were 78.1% more Males than Females in the sample, and 63.8% of participants were between the ages of 40 and 69. This discovery may be related to the fact that chronic diseases begin to manifest at this age, while SARS-CoV-2 infection prevalence peaked at the age of forty. The previous finding was consistent with Kayaaslan’s findings (Kayaaslan et al., 2021) [14] , but they were in conflict with Galal et al.’s findings (Galal, et al., 2021) [13] , where a significant portion of their cohort was in the age range of 21 to 40. Compared to M. Augustin et al. (2021) [15] almost all of the current cohort (71.04%) had mild COVID-19 infection with mild symptoms, while only 13% and 5%, respectively, had severe and extremely severe SARS-CoV-2 infections. Regarding the mentioned before most of the cohort had mild infections where they were not hospitalized during the acute phase and the mean length of infection was 3.00 ± 2.181 months. Recently, the time span to qualify for the post syndrome was > 28 - 30 days - 60 days (Sudre CH. 2020) [16] , or more than 3 months (Townsend L et al. 2020 [17] , Carvalho-Schneider C, et al., 2020 [18] .

Prior to acquiring COVID-19, 55.48% of participants did not have any chronic diseases, while comparable studies revealed that 75% of patients did not have any comorbid disorders (Hussein et al., 2020) [19] . Conversely, the most prevalent co-occurring diseases in the population were hypertension, bronchial disease, diabetes, and liver disease. On the other hand, heart issues, autoimmune diseases, and cancer diseases, which were consistent with M. Augustin et al. (2021) [15] , and Lechien JR et al. (2020) [20] findings demonstrate the minor frequency of associated illness.

Analogous to COVID-19 infection symptoms 8 (2.7%) patients of 301 their infection was symptomless while more than half of participants (56.8%) had fatigue as an apparent symptom followed by fever, New Loss of sense of taste and smell (44.2%, 40.2% respectively). Whereas, Headache was not the most prevalent symptom (24.9%), which was in contrast with Lechien JR results where they found that headache is the most prevalent symptom at the onset of illness followed by a new loss of sense of taste and smell. on the other hand, our findings were in line with Morgul, et al., (2021) [21] who found that 64.1% of participants suffered from fatigue as an observed symptom.

Recently, it has become clear that some SARS-CoV-2 infection convalescent patients continued to have some symptoms for a period reached to months after the onset of COVID-19 infection without considering the severity of the disease (Chopra V et al., 2020) [22] . Up to now, there is no exact terminology to define this case, there for, this clinical case may expressed as long COVID (Mandal S, et al. 2021) [23] , chronic COVID syndrome(Baig AM, 2020) [24] , post-acute COVID-19 syndrome(IDSA, 2020) and post-COVID syndrome (Goertz YMJ et al., 2020) [25] . In the current study, we choose Post-COVID Syndrome (PCS).

We found that whereas 94.7% of the population had PCS and fatigue was the most commonly reported persistent symptom with the findings of Townsend L et al. (2020) [17] and Marshall M et al. (2020) [26] , just sixteen (5.3%) of the COVID-19 treated patients had no post-COVID symptoms. One of the most recurrences of COVID-19 lasting symptoms was fatigue, which may be caused by brain capillary endothelial dysfunction, as reported by Nauen DW et al. in 2021 [27] . Fatigue was followed by a fresh loss of taste and smell, followed by a persistent cough in 13.6% of participants, which was the post-symptom, the outcomes were consistent with an Italian study. (Angelo Carf et al. 2020) [28]

Synonymous to vaccinations, 61.8% of participants rejected to take advantage of the available COVID vaccine, which may have been because they had sufficient knowledge about the vaccine or were reluctant to have one. The adverse effects of the vaccinations and the lack of confidence in their efficacy may also be contributing factors to the population’s resistance to the vaccine. This finding was consistent with a related Ethiopian study (Delelegn Yehualashet, et al., 2022) [29] Other participants were given vaccines from Sinovac, Sinofarm, Sputnik, AstraZeneca, as well as additional manufactured vaccines. Astrazeneca’s percentage was larger than the others because it is suggested for older age groups.

Corresponding to our research 37.9% received oral vitamins, minerals and analgesics as a treatment for COVID-19 infection, while 24.6% of the contributors used oral antibiotics over the vitamins, minerals, and analgesics. However, only 5% of the patients received oxygen therapy, cortisone, and anticoagulant, and 6.3% of contributors were hospitalized. The results mentioned previously confirm that mild cases were prevalent in general and that serious instances were extremely uncommon in the cohort. Thus only 5.3% did not receive any therapy which in contrast with Lechien JR finding where they revealed that about 29% of the patients did not receive any drug and about 7% had antibiotics.

In the current study, PCS was independently predicted by diarrhea, cough, and headache following acute COVID-19 infection (p-values 0.611, 0.407, and 0.052 respectively). While diarrhea at the time of disease onset was an independent predictor for PCS, gender was a dependent indicator for PCS with a p-value of 0.002, which was consistent with research by M. Augustin et al. from 2021 [15] . In contrast, men are more likely than women in our research to be accepted for PCS. Furthermore, age is a dependent predictor for long-term COVID-19 symptoms, they revealed that cases older than 65 have more acceptability to have PCS than people aged from 18 to 64. The p-value for this relationship was 0.016, which was in accordance with Bull-Otterson et al.’s findings in 2022 [30] .

Considering the comorbidities of the cohort applicant, diabetes and hypertension were associated with an increased risk of having a severe condition, with a p-value of 0.05 indicating a relationship between the severity of the disease and them. Also Peng, M., et al. (2021) [31] reported that myocardial damage from COVID-19 infection and long-term hypertension may both cause organ damage, including heart injury. Similarly, they demonstrated that hypertension has a crucial role in controlling the immune system, the gastrointestinal system, and inflammation, which shows the severity of the COVID-19 disease in hypertensive patients. Sen, S., et al. [32] , further indicate that diabetes is linked to decreased body immunity and increased SARS-CoV-2 replication, which may be an indicator of the severity of COVID-19 disease. On the other hand, there was a significant correlation between diabetes as a comorbid condition and cough as a PCS (p-value = 0.004), which was consistent with Li, G., et al.’s (2020) [33] finding that the cough may be a more prevalent feature of SARS-CoV-2 infection in diabetic patients than in non-diabetic patients. Finally, the treatment approach that had been used in Libya to treat Covid-19 infected patients had no effect on preventing PCS in those who survived, where the p-value was 0.105 which was contraindicated with Xie Y., et al. (2023) [34] results, based on findings showed that utilizing the antiviral drug (nirmatrelvir) is linked to a decrease in the long-lasting Covid-19 effects.

Our study discussed PCS in the population who were not admitted to or attended by hospitals, and we concentrated on all PCS rather than just two or three, from which participants may select the recurrent symptoms they experienced. However, smoking was not considered a characteristic of PCS in the current investigation. Alternatively, comorbidity was evaluated as a criterion for SARS-CoV-2 convalescent patients. Further, the questionnaires were assigned at random throughout the city using several techniques, including in-person and online. In comparison, the males were quite more than females in our cohort.

The COVID-19 disease and Post-COVID Syndrome (PCS) were reviewed in the present research, which revealed many criteria that had an impact on them. The most frequent persistent symptoms (PCS) reported by patients for longer than two months were fatigue, new loss of taste as well as smell, and cough. Less frequently reported PCS included lung problems, headaches, and diabetes. In Benghazi’s population, the symptoms were more persistent in the males than the females, Additional signs like diarrhea and headaches did not point to PCS. It should confirm that PCS can manifest even in those with moderate SARS-CoV-2 infections.
