A New Study Suggests COVID-19 Reinfection Is Possible. Here ’s What to Know

Preliminary research released Monday suggests it’s possible to get COVID-19 twice—but experts say the news is not as concerning as that headline may seem. The new research, which was accepted for publication in the journal Clinical Infectious Diseases, details the case of a 33-year-old man living in Hong Kong. He first tested positive for COVID-19 in late March and developed symptoms including cough, sore throat, fever and headache. He made a full recovery, but again tested positive for COVID-19 while traveling home from Europe in mid-August. This time, he did not have any symptoms. The Hong Kong-based researchers behind the study say the man’s case is the first proven example of reinfection with SARS-CoV-2, the virus that causes COVID-19. There have been other documented cases of patients who tested positive for COVID-19 multiple times, but it has not been clear whether they’re truly reinfected or if some of the virus’ genetic material lingers within the body, leading to repeated positive tests. Viral sequencing, however, showed the Hong Kong patient was infected by two different strains of SARS-CoV-2, which suggests he indeed got sick twice. But in some ways, the case is actually encouraging, says Akiko Iwasaki, a professor of immunobiology at the Yale School of Medicine who was not involved in the study. “There’s no need to panic over this reinfection news,” Iwasaki says. “Even though he got reinfected…this is a...

CONCLUSION: According to the Centers for Disease Control, common symptoms of human coronavirus include fever, cough, runny nose, sore throat, and headache. In the case of SARS-CoV-2, there are limited reports about headaches, one of the most common clinical manifestations. There are currently no studies that focus specifically on headache among patients with SARS-CoV-2 infection. PMID: 33017479 [PubMed - as supplied by publisher]

Abstract Interspecies transmissions of viruses between animals and humans may result in unpredictable pathogenic potential and new transmissible diseases. This mechanism has recently been exemplified by the discovery of new pathogenic viruses, such as the novel severe acute respiratory syndrome corona virus-2 (SARS-CoV-2) pandemic, Middle-East respiratory syndrome-coronavirus epidemic in Saudi Arabia, and the deadly outbreak of Ebola in West Africa. The. SARS-CoV-2 causes coronavirus disease-19 (COVID-19), which is having a massive global impact in terms of economic disruption, and, above all, human health. The di...

ConclusionsThis report suggested that, in the early phase of COVID-19 pneumonia, routine screening could miss patients who were virus carriers. Highlighting travel history is of paramount importance for the early detection and isolation of severe acute respiratory syndrome coronavirus 2 cases.

CONCLUSIONS: SARS-Cov-2 has emerged as a worldwide threat, currently affecting 170 countries and territories across the globe. There is still much to be understood regarding SARS-CoV-2 about its virology, epidemiology and clinical management strategies; this knowledge will be essential to both manage the current pandemic and to conceive comprehensive measures to prevent such outbreaks in the future.

n B Abstract After the emergence of a novel coronavirus named SARS-CoV-2, coronavirus disease 2019 (COVID-19) was initially characterized by fever, sore throat, cough and dyspnea, mainly manifestations of respiratory system. However, other manifestations such as headache, abdominal pain, diarrhea, loss of taste and smell were added to the clinical spectrum, during the course of the COVID-19 pandemic. The reports on the neurological findings are increasing rapidly and headache seems to be the leader on the symptom list. Headache was reported in 11-34% of the hospitalized COVID-19 patients, but clinical features of ...

This article is a narrative review with the aim of analyzing the current literature on postviral olfactory dysfunction (OD) related to SARS-CoV-2 pandemics. Since the initial anecdotal reports from China, international reports on COVID-19 patients have been increasing, describing a 5% to 85% range of loss of smell. To date, the literature is widely heterogeneous regarding the loss of smell; therefore, we advise home isolation measures and/or social distancing, and to carry out diagnostic tests for SARS-CoV-2 when possible in those patients with sudden and severe loss of smell who cannot be promptly evaluated. PMID: 32...
