Coronavirus disease 2019 (COVID-19) is the health crisis of our time and a great challenge we face, requiring the implementation of worldwide general containment. The symptoms and complications of COVID-19 are diverse, and rhabdomyolysis is an atypical manifestation. We report a case of a 63-year-old patient, admitted to the emergency room for myalgia and fever evolving over 5 days, in whom laboratory and other examinations indicated rhabdomyolysis complicated by renal insufficiency. During the diagnostic workup, the real-time polymerase chain reaction (RT-PCR) test result for COVID-19 was positive, revealing infection with sudden acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Although the severity of COVID-19 infection relates mainly to acute respiratory syndrome, other complications can be prognostic, and these complications make the management of this disease difficult. Rhabdomyolysis is one of the fatal complications; first, because the pathophysiological mechanism is not yet understood, and second, because rhabdomyolysis, itself, is usually complicated by acute renal failure. This complication makes the disease management difficult, especially in patients with SARS. Rhabdomyolysis during COVID-19 infection represents a significant challenge, given the few reported cases, and further research is required to develop a therapeutic consensus.

Urgent measures were taken for those at the age of 65 and over who were at the risk group all over the world due to the COVID-19 pandemic. It is known that many individuals at the age of 65 and over have experienced anxiety due to the uncertainties. This study aimed to determine the anxiety and death anxiety in individuals aged 65 and over who were isolation at home due to being diagnosed with COVID-19 or being in contact during the pandemic process. The study is descriptive and cross-sectional. It was performed with 656 home-quarantined individuals aged between 65–80 years with positive or negative real-time polymerase chain reaction (RT-PCR) test result. A form including questions about the death anxiety and the Coronavirus Anxiety Scale Short Form prepared by the researchers were administered to the individuals by phone call. Of the participants, 49.5% were male. Median COVID-19 anxiety score was 4 (0–18). Anxiety scores of the male and female participants were similar. Participants with negative polymerase chain reaction (PCR) results and those with death anxiety had higher COVID anxiety scores. Death anxiety has increased by 1.661 times in male gender, 1.983 times in RT-PCR positivity and 0.146 times in the presence of symptoms. Individuals with positive COVID-19 test results or those aged 65 and over who had death anxiety and negative COVID-19 test result but who were in home-isolation due to being a contact had higher anxiety score. For this reason, those with death anxiety can be supported in line with their religious beliefs to reduce anxiety. Those with negative PCR test results in quarantine can be adequately informed about the COVID-19.

A large number of patients with coronavirus disease 2019 (COVID-19) present at hospitals. There are a limited number of isolation rooms open, and patients must often wait a long time to get a reverse transcription-polymerase chain reaction (RT-PCR) test done. This necessitates the introduction of effective triage plans. A patient with suspicions is referred to an emergency room (ED) depending on their medical record for a simple physical assessment, blood test findings, and chest imaging.A retrospective study design was conduct at Prince Sultan Medical Military City (PSMMC). Ethical approval was obtained from the institutional board to wave the consent forms since it is a retrospective study. Only the primary investigator has had the data access to the patients’ medical records. The collected patient records were under specific categories, including symptoms score starts from 5 and above, RT-PCR test result done after CXRP imaging, the patient admitted to the emergency department (ED). Excluding all CXRP done after RT-PCR TEST, positive Covid 19 admitted to the intensive care unit (ICU), pediatric patients, and patients with score symptoms were less than five. Two experienced radiologists reviewed the images blindly, and the inter-observer reliability of observations noted by the radiologists was calculated. As for the relationship between the x-ray reading and the RT-PCR test result, our results showed a high correlation between the variables (chi-square χ² = 12.44, with df =1, and p<0.001). The sensitivity of x-ray diagnosing covid19 was 65.52 %, while the specificity was 54.51 %, and the accuracy of radiologists reading was 58.17 %. Furthermore, the positive predictive value (PPV) was 41.76 %, and the negative predictive value (NPV) was 76.05%. Finally, the false positive rate (type-i error (alpha) was 45.49%, and the false-negative rate (type-ii error (beta) was 34.48% Our research findings show that CXRP imaging can detect COVID-19 infection in symptomatic patients and can be a valuable addition to RT-PCR testing. In an inpatient ED environment where availability of test kits, laboratory equipment, and laboratory personnel is compromised and risks delaying patient treatment and hospital workflow, serial CXRP could theoretically be used as an adjunct diagnostic function and monitoring in patients suspected of having COVID-19.

Abstract The current discharge criteria for COVID-19 require that patients have 2 consecutive negative results for reverse transcription polymerase chain reaction (RT-PCR) detection. Here, we observed that recurrent positive RT-PCR test results in patients with 3 consecutive negative results (5.4%) were significantly decreased compared with those in patients with 2 consecutive negative results (20.6%); such patients reported positive RT-PCR test results within 1 to 12 days after meeting the discharge criteria. These results confirmed that many recovered patients could show a positive RT-PCR test result, and most of these patients could be identified by an additional RT-PCR test prior to discharge.

Abstract The objective of this study was to describe the epidemiology of COVID-19 in Nigeria with a view of generating evidence to enhance planning and response strategies. A national surveillance dataset between 27 February and 6 June 2020 was retrospectively analysed, with confirmatory testing for COVID-19 done by real-time polymerase chain reaction (RT-PCR). The primary outcomes were cumulative incidence (CI) and case fatality (CF). A total of 40 926 persons (67% of total 60 839) had complete records of RT-PCR test across 35 states and the Federal Capital Territory, 12 289 (30.0%) of whom were confirmed COVID-19 cases. Of those confirmed cases, 3467 (28.2%) had complete records of clinical outcome (alive or dead), 342 (9.9%) of which died. The overall CI and CF were 5.6 per 100 000 population and 2.8%, respectively. The highest proportion of COVID-19 cases and deaths were recorded in persons aged 31–40 years (25.5%) and 61–70 years (26.6%), respectively; and males accounted for a higher proportion of confirmed cases (65.8%) and deaths (79.0%). Sixty-six per cent of confirmed COVID-19 cases were asymptomatic at diagnosis. In conclusion, this paper has provided an insight into the early epidemiology of COVID-19 in Nigeria, which could be useful for contextualising public health planning.

Abstract We studied the pattern and duration of viral RNA shedding in 32 asymptomatic and 11 pauci-symptomatic coronavirus disease 2019 (COVID-19) cases. Viral RNA shedding in exhaled breath progressively diminished and became negative after six days of a positive reverse transcription polymerase chain reaction (RT-PCR) test. Therefore, the duration of isolation can be minimised to six days.

Recently, an argument was put forth because a symptomatic and positive patient for CoVID-19 turned tested negative after 7 days, so discharged from the hospital. Both at the time of admission and discharge real-time reverse transcriptase Polymerase Chain Reaction (RT-PCR) was done for testing of CoVID-19. Immediately, patient again developed respiratory symptoms and was admitted to hospital again. Amidst of current CoVID-19 pandemic, a question was asked “What is the specificity of the Real Time-Polymerase Chain Reaction (RT-PCR) test for COVID-19?” with an assumption that what if at the time of discharge the disease is present in patient but test turned out to be negative? In response to that a counter statement was posed that “It is the sensitivity that should be asked rather than specificity”. It was based on the implication of primary question that was implying false negative report of the RT-PCR. It means, since patient was discharged with negative result that could be false negative.

As the SARS-CoV-2 (COVID-19) pandemic spreads rapidly, there is need for a diagnostic test with high accuracy to detect infected individuals especially those without symptoms. Real-time polymerase chain reaction (RT-PCR) is a common molecular test for diagnosing SARS-CoV-2. If some factors are not taken into consideration when performing this test, it can have a relatively large number of false negative results. In this article, we discuss important considerations that could lead to false negative test reduction.

Humanity is going through never seen before health crisis due to the outbreak of novel coronavirus or Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2). There are 24.02 million cases and 0.82 million deaths worldwide as of 26th August 2020 due to deadly infection of COVID-19. The disease has been spreading exponentially (R-naught number: 3) and has challenged even the best healthcare infrastructure in the world. With the progression of the disease, the countries shifted the focus from cure to diagnosis and containment to flatten the curve. The review shows that the disease is spreading exponentially while the resources are still limited. We focus upon the probable vectors of the virus, different diagnostic methods with advantages & limitations, and the way forward. This review article covers the different diagnostic methods with more advantages, limitations, and the future sneak-peek into the forthcoming developments for the diagnostic processes such as RT-PCR (Reverse Transcription Polymerase chain reaction).

Background: A seroprevalence study for COVID-19 antibodies was conducted amongst health workers in Mumbai, India, in June 2020.Methods: Healthcare workers (n=801) underwent a cross sectional survey through electrochemiluminescence immunoassay (Roche diagnostics’ Elecsys anti-SARS-CoV-2 assay, Roche diagnostics, Rotkreuz, Switzerland).Results: Of the 801 healthcare workers, 62 who had been previously diagnosed with a real time-polymerase chain reaction (RT-PCR) proven SARS-CoV-2 infection, 45 (73.6%) were found to be seronegative during the study. The duration between the positive RT-PCR test and the serological testing ranged from 15 to 49 days for 34 (54.8%), and was >50 days in 28 subjects. Up to 28 days after a positive PCR test, 90% of the subjects were found to be seropositive, but this reduced to less than half over the next two weeks (38.5% between 29 and 42 days).Conclusions: Our findings are in agreement with previous reports that demonstrate a peak antibody formation after 3 weeks, and also an early antibody decay that is almost exponential. This may also have a significant effect on the protection vaccines are able to provide considering that a natural infection has such a transient antibody response.

INTRODUCTION: Clinical and laboratory features of enteroviral meningitis may overlap with those of bacterial meningitis. In the present retrospective review, we compared features of enteroviral (EV)-positive and -negative patients to determine those that were most influential in admission, discharge and in anti-infective administration.METHODS: Data were analyzed from the records of 117 pediatric and adult patients who underwent cerebrospinal fluid (CSF) EV testing over a three-year period.RESULTS: The oldest EV-positive patient was 34 years of age and the occurrence of the disease was highly seasonal. EV-positive patients were more likely to report fever, rash, photophobia, short onset and exposure to an ill contact. A positive polymerase chain reaction (PCR) result was associated with relatively short hospitalization. Seizure and neurological symptoms were more strongly associated with a negative PCR test result. CSF characteristics did not discriminate well between patients with positive and negative PCR tests. Patients with imperfect Glasgow Coma Scores or with neurological symptoms were more likely to be admitted to hospital than those without. Fever and recent onset predicted determinants of anti-infective use.CONCLUSION: The present retrospective study confirms previous reports regarding seasonality and the young age of positive patients. Factors that indicate nonenteroviral etiology were appropriately also those that influenced hospitalization. Patients with EV meningitis were likely to be treated with empirical anti-infectives, and a substantial proportion continued to take antibiotics for more than 24 h after receiving the positive EV PCR test result.
