South Korea Confirms First Case of MERS Since 2015

Most of the 38 deaths that occurred due to the virus in South Korea were elderly people or patients affected by other illnesses.

South Korean authorities on Sunday confirmed the first case of the Middle East Respiratory Syndrome (MERS) coronavirus since the outbreak that affected the country in 2015 leaving 187 infected and 38 dead.

The patient, a 61-year-old man, was diagnosed with the virus on Saturday after returning from a business trip in the United Arab Emirates (UAE) with transit in Kuwait, the Korea Centres for Disease Control and Prevention (KCDC) said.

The South Korean government has convened an emergency meeting to analyse the situation and take preventive measures.

The patient was admitted to a hospital in Kuwait when he began to show some symptoms of the disease and upon arrival to South Korea was transferred to the Samsung Medical Centre in Seoul.

 

The hospital alerted the authorities that it could be a possible case of MERS as symptoms included high fever and pneumonia and moved the patient to the Seoul National University Hospital where he tested positive for the potentially deadly virus.

Around 20 people who were in close contact with the patient, including passengers and crew members of his flight and immigration officers, have been quarantined to prevent the spread of the virus.

This is the first case of MERS in South Korea since its outbreak recorded between May and December 2015, after this virus was first detected in Saudi Arabia in 2012 and subsequently expanded to other countries.

The mortality rate of MERS in South Korea reached 20 per cent during the outbreak, below the figures between 30 and 40 per cent that were recorded in other areas.

Here’s Why Vaping Can Make You More Prone To Inflammation and Infection

Using e-cigarettes alters the mouth’s microbiome — the community of bacteria and other microorganisms — and makes users more prone to inflammation and infection, researchers have found.

While vaping has quickly grown in popularity in recent years, a growing number of people are falling ill or dying from vaping-related illnesses, the study said.

“Our study suggests that vaping electronic cigarettes causes shifts in the oral environment and highly influences the colonisation of complex microbial biofilms, which raises the risk for oral inflammation and infection,” said Indian-origin researcher and study co-author Deepak Saxena from the New York University in the US.

“Given the popularity of vaping, it is critical that we learn more about the effects of e-cigarette aerosols on the oral microbiome and host inflammatory responses in order to better understand the impact of vaping on human health,” said co-senior author Xin Li. For the study, published in the journal iScience, the research team examined e-cigarette vapour and its influence on the oral microbiome and immune health.

“The oral microbiome is of interest to us because research shows that changes in its microbial community as a result of environmental and host factors contribute to a range of health issues, including cavities, gum disease, halitosis, and medical conditions such as diabetes, cardiovascular disease, and cancers,” Saxena said. They also evaluated how vaping influences infection efficiency of oral pathogens in cell lines using a novel e-cigarette aerosol generating machine and measured pro-inflammatory immune mediators.

Through oral exams and saliva samples, the researchers studied the oral microbiome of 119 human participants from three groups: e-cigarette users, regular cigarette smokers, and those who had never smoked. Gum disease or infection was significantly higher among cigarette smokers (72.5 per cent), followed by e-cigarette users (42.5 per cent) and non-smokers (28.2 per cent).

Using 16S rRNA high throughput sequencing, a technique used to profile microbial communities, the researchers observed different microorganisms in the saliva of e-cigarette users, cigarette smokers, and non-smokers. For instance, e-cigarette users had an abundance of Porphyromonas bacteria, while an increase in Veillonella bacteria was found in both e-cigarette and cigarette users.

“The predominance of these periodontal pathogens in the mouths of e-cigarette users and traditional smokers is a reflection of compromised periodontal health,” said Li.

The researchers also found that the altered microbiome in e-cigarette users influenced the local host immune environment compared to non-smokers and cigarette smokers. IL-6 and IL1ß — cytokines involved in inflammatory responses — were highly elevated in e-cigarette users. Cell studies also showed upregulation of IL-6 after exposure to e-cigarette aerosols, resulting in an elevated inflammatory response.

Moreover, e-cigarette aerosols made cells prone to bacterial infection, which points to a greater risk for infection in e-cigarette users, the study said. (IANS)
