(Press-News.org) WASHINGTON - The ongoing outbreak in the Republic of Korea (South Korea) is an important reminder that the Middle East respiratory virus (MERS-CoV) requires constant vigilance and could spread to other countries including the United States. However, MERS can be brought under control with effective public health strategies, say two Georgetown University public health experts.
In a JAMA Viewpoint published online June 17, Georgetown public health law professor Lawrence O. Gostin and infectious disease physician Daniel Lucey outline strategies for managing the outbreak, focusing on transparency, trust and infection control in health care settings. The duo also outline weaknesses in a World Health Organization's (WHO) framework designed to govern patents on certain viruses, which is likely to impact critical future research.
MERS-CoV, which affects the respiratory system and is sometimes fatal, was first diagnosed in 2012 in Saudi Arabia. The first outbreak occurred that year in Jordan with nine laboratory-confirmed cases. In May 2015, South Korea reported what has been described as a "super-spreading" event with dozens diagnosed MERS-CoV cases after exposure to a single patient. While more difficult to spread person-to-person than its cousin, SARS, MERS-CoV is most likely to spread in health care environments.
"South Korea repeated many of the fundamental mistakes evident during the SARS and Ebola epidemics: lack of transparency, poor infection control, and social disruption, including unnecessary school closures," says Gostin.
"Public health measures--infection prevention and control, isolation, contact tracing, and quarantine--historically have controlled MERS-CoV and were also widely employed during SARS and Ebola outbreaks," Gostin and Lucey write.
However, they point out that public fear and government mistrust can hinder effective epidemic response.
"In the case of MERS-CoV, health authorities initially withheld the names of hospitals handling cases. Transparency builds public trust; given the scientific uncertainty, health authorities should fully disclose what is and is not known about the MERS-CoV outbreak."
Key points Gostin and Lucey make about MERS-CoV infection control include:
Training health workers and conducting diagnostic testing of certain travelers;
Limiting quarantine quarantines use to well-documented exposures using the least restrictive means possible;
Restricting travel should be avoided as it would be ineffective as evidence is lacking of MERS-CoV community transmission; and
Closing schools also should be avoided given the lack of community transmission of MERS-CoV.
In addition, Gostin and Lucey point out that deficiencies in a WHO framework for virus sharing have led to challenges of intellectual property ownership of MERS-CoV that could hinder research.
After Saudi Arabia sent blood samples to Erasmus Medical Center in the Netherlands and MERS-CoV was identified, Erasmus filed for a patent. Saudi Arabia says that action violates national rules and that Erasmus acted unethically.
Gostin and Lucey say the WHO's Pandemic Influenza Preparedness Framework fails to cover non-influenza pathogens like MERS-CoV noting, "...there remain substantial holes in international rules needed to facilitate critical research."
In conclusion, the two public health experts say that by fully funding and implementing requirements put forth in WHO's International Health Regulations, such as building core capacities (diagnosis, treatment, laboratories contact tracing and human forms of quarantine) offers "the best assurance of global health security."

Chicago, June 17, 2015 - Being the daddy isn't important for male gorillas when it comes to their relationships with the kids; it's their rank in the group that makes the difference, says new research published in Animal Behaviour. The authors of the study, from the University of California, Los Angeles (UCLA) - now with Lincoln Park Zoo in Chicago - the Dian Fossey Gorilla Fund International (Atlanta USA) and the Max Planck Institute for Evolutionary Anthropology (Leipzig, Germany) say this supports the theory that for most of their evolution, gorillas lived in groups ...
A multi-institutional team of scientists has taken an important step in understanding where atoms are located on the surfaces of rough materials, information that could be very useful in diverse commercial applications, such as developing green energy and understanding how materials rust.
Researchers from Northwestern University, Brookhaven National Laboratory, Lawrence Berkeley National Laboratory and the University of Melbourne, Australia, have developed a new imaging technique that uses atomic resolution secondary electron images in a quantitative way to determine ...
Reducing short breaks between shifts helps nurses recover from work, according to a new study from Finland. The study analysed the effects of longer rest and recovery periods between shifts on heart rate variability, which is an indicator of recovery.
Shift work can increase the risk of many diseases, for example cardiovascular diseases. The increased risk is partially caused by insufficient recovery from work, which interferes with the normal function of the autonomic nervous system regulating heart function and blood pressure, among other things. Nurses have too little ...
People make dramatically different decisions about who should receive hypothetical transplant organs depending on whether the potential recipients are presented as individuals or as part of a larger group, according to new research published in Psychological Science, a journal of the Association for Psychological Science. The findings show that when recipients are considered in groups, people tend to allocate organs equally across the groups, ignoring information about the patients' chances of success.
"This is important because public policies about prioritizing resources ...
June 17, 2015 (Washington, D.C.) - Whether sealed with a handshake, a million-dollar contract, or a string of curses, every business deal is a reflection of trust. Both parties trust that the other will hold up their end of the bargain. Good negotiators have a store of social capital before bargaining begins; built up through interactions outside the negotiations that establish trust. Working with a team of researchers from Ludwig-Maximilians-Universität and Technische Universität in Munich, Germany, American University's Kogod School of Business professor of ...
Someday, treating patients with nanorobots could become standard practice to deliver medicine specifically to parts of the body affected by disease. But merely injecting drug-loaded nanoparticles might not always be enough to get them where they need to go. Now scientists are reporting in the ACS journal Nano Letters the development of new nanoswimmers that can move easily through body fluids to their targets.
Tiny robots could have many benefits for patients. For example, they could be programmed to specifically wipe out cancer cells, which would lower the risk of complications, ...
Needle injections have been around since 1657 and remain a key delivery method for many drugs, including vaccines that have prevented countless illnesses. But for patients that require daily pricks or for people in remote locations, the syringe model has major drawbacks. An article in Chemical & Engineering News looks at potential alternatives, their successes and their roadblocks.
Alex Scott, a senior editor at C&EN, explains that many pharmaceuticals, particularly large-molecule drugs such as insulin, are not good candidates for oral delivery. If swallowed, they would ...
A new approach to skin rejuvenation developed at Massachusetts General Hospital (MGH) may be less likely to have unintended side effects such as scarring and altered pigmentation. In the online journal Scientific Reports, an MGH research team reports that treatment with pulsed electric fields - a noninvasive procedure that does not involve the generation of heat - removed skin cells in an animal model without affecting the supporting extracellular matrix, eventually leading to renewal of the skin surface.
"We showed that non-thermal pulsed electric field or PEF treatment ...
ANN ARBOR--A University of Michigan researcher and his colleagues are forecasting an average but still large "dead zone" in the Gulf of Mexico this year.
The forecast calls for an oxygen-depleted, or hypoxic, region of 5,483 square miles, roughly the size of Connecticut. It was announced today by the U.S. National Oceanic and Atmospheric Administration, which sponsors the work.
Farmland runoff containing fertilizers and livestock waste, much of it from as far away as the Corn Belt, is the main source of the nitrogen and phosphorus that cause the annual Gulf of Mexico ...
