COVID-19 may be transmitted through the eye, report finds

A new report published by JAMA Ophthalmology found preliminary data may suggest SARS-CoV-2, the virus that causes COVID-19, might be transmitted through the eye. Researchers analyzed data from 38 patients infected with COVID-19 from Hubei Province, China, and found 12 (31.6%) individuals had ocular manifestations, including epiphora, conjunctival congestion, or chemosis. These symptoms commonly occur...

Impact of asymptomatic carriers on COVID-19 transmission

Asymptomatic carriers of the virus display no clinical symptoms but are known to be contagious. Recent evidence reveals that this sub-population, as well as persons with mild symptoms, represent a major contributor in the propagation of COVID-19. The asymptomatic sub-population frequently escapes detection by public health surveillance systems. Because of this, the currently accepted estimates...

Evaluating the effectiveness of social distancing interventions against COVID-19

The term ‘flatten the curve’, originating from the Centers for Disease Control and Prevention (CDC), has been used widely to describe the impact of social distancing interventions. A new study based in a mathematical model ―age-structured Susceptible-Exposed-Infectious-Removed (SEIR) model, to describe the transmission of COVID-19―, to investigate the effectiveness of social distancing interventions lasting six...

Imperial College predicts that we will be able to go outside one in three months due to the coronavirus

There are two main challenges in assessing the severity of clinical outcomes during an epidemic of a newly emerging infection such as COVID-19. The first one ―surveillance―, is typically biased towards detecting clinically severe cases, particularly at the start of an epidemic when diagnostic capacity is limited (estimates of the proportion of fatal cases), the...

Effects of temperature on COVID-19 transmission

When the SARS outbreak happened in 2002-2003, SARS-CoV spread to approximately 30 countries only. However, the current outbreak of COVID-19 by SARS-CoV-2 has spread to 176 countries or territories which suggests the enhanced ability of viruses to be aerosolized. Environmental factors such as atmospheric temperature also can modulate the survival and spread of virus aerosols...

Coincidence of COVID-19 epidemic and olfactory dysfunction outbreak

Because of the newly identified virus, it is expected that new reports about different aspects of the disease will be released daily. In this way, an update on its clinical and laboratory presentations has reported fever, respiratory symptoms, cough, fatigue, myalgia, arthralgia and breathing difficulties as the common presentations of the confirmed cases. However, recent...

Caution on kidney dysfunctions of COVID-19 patients

To date, large amounts of epidemiological and case study data have been available for the COVID-19, which suggested that the mortality was related to not just respiratory complications. A new study analyzed kidney functions in COVID-19 patients and their relations to mortality. In this sense, in this multi-centered, retrospective, observational study, researchers included 193 adult...

Relationship between the ABO blood group and the COVID-19 susceptibility, study finds

A study have compared the ABO blood group distribution in 2,173 patients with COVID-19 confirmed by SARS-CoV-2 test from three hospitals in Wuhan and Shenzhen, China, with that in normal people from the corresponding regions. Recent clinical observation suggests that patient age, male sex and certain chronic medical conditions (e.g., cardiovascular disease, diabetes, COPD) seem...

Cepheid molecular test for the qualitative detection of SARS-CoV-2

Cepheid has developed an automated molecular test for the qualitative detection of SARS-CoV-2, the virus that causes COVID-19. The test leverages the design principles of Cepheid current Xpert® Xpress Flu/RSV cartridge technology, in which multiple regions of the viral genome are targeted. The test can provide rapid detection of the current pandemic coronavirus SARS-CoV-2 in...
