Like other CoVs, it is sensitive to ultraviolet rays and heat. Furthermore, these viruses can be effectively inactivated by lipid solvents including ether (75%), ethanol, chlorine-containing disinfectant, peroxyacetic acid and chloroform except for chlorhexidine.


According to the World Health Organization (WHO), viral diseases continue to emerge and represent a serious issue to public health. In the last twenty years, several viral epidemics such as the severe acute respiratory syndrome coronavirus (SARS-CoV) in 2002 to 2003, and H1N1 influenza in 2009, have been recorded. Most recently, the Middle East respiratory syndrome coronavirus (MERS-CoV) was first identified in Saudi Arabia in 2012.

In a timeline that reaches the present day, an epidemic of cases with unexplained low respiratory infections detected in Wuhan, the largest metropolitan area in China’s Hubei province, was first reported to the WHO Country Office in China, on December 31, 2019. Published literature can trace the beginning of symptomatic individuals back to the beginning of December 2019. As they were unable to identify the causative agent, these first cases were classified as “pneumonia of unknown etiology.” The Chinese Center for Disease Control and Prevention (CDC) and local CDCs organized an intensive outbreak investigation program. The etiology of this illness is now attributed to a novel virus belonging to the coronavirus (CoV) family.

On February 11, 2020, the WHO Director-General, Dr. Tedros Adhanom Ghebreyesus, announced that the disease caused by this new CoV was a “COVID-19,” which is the acronym of “coronavirus disease 2019”. In the past twenty years, two additional coronavirus epidemics have occurred. SARS-CoV provoked a large-scale epidemic beginning in China and involving two dozen countries with approximately 8000 cases and 800 deaths, and the MERS-CoV that began in Saudi Arabia and has approximately 2,500 cases and 800 deaths and still causes as sporadic cases.

It is vital that would-be bombmakers be disabused of any notion that they could evade tough international sanctions. We need a country-neutral, reasonably predictable, more-or-less automatic sanction regime that puts all countries on notice, even friends of the powerful.

Just as we’ve had to discard business-as-usual thinking to deal with the current worldwide health emergency; it’s time to get serious about the spread of nuclear weapons. It doesn’t have the immediacy of the coronavirus, but it will last a lot longer and is no less threatening. In particular, we need to fortify the Nuclear Nonproliferation Treaty (NPT), which is fifty years old this year and badly needs fixing. The April 2020 Review Conference will likely be postponed, which provides time to develop something more than the usual charade of incremental proposals that nibble at the problem.

Despite messages from some health officials to the contrary, it’s likely that a mask can help protect a healthy wearer from infection, says Benjamin Cowling, an epidemiologist at the University of Hong Kong. Both surgical masks and the more protective N95 respirators have been shown to prevent various respiratory infections in health care workers; there’s been some debate about which of the two is appropriate for different kinds of respiratory infection patient care. “It doesn’t make sense to imagine that … surgical masks are really important for health care workers but then not useful at all for the general public,” Cowling says.


Some argue that masking everyone would slow the spread of COVID-19—but the evidence is spotty.

Chronic lung diseases, including chronic obstructive pulmonary disease, asthma, lung cancer and pulmonary fibrosis, are the second leading cause of death in the world. Currently, only limited therapeutic options exist for chronic lung diseases; in particular, causative therapeutic approaches are missing. Lung transplantation remains the only available therapy for many patients with end-stage lung disease; however, the number of patients listed for lung transplantation by far surpasses the number of suitable donor organs.

Beyond lung transplantation, several approaches to repair and regenerate lung tissue, with the aim of restoring lung function, have made substantial progress in recent years and hold great promise for future therapies. Importantly, advancement in our understanding of the underlying pathogenesis of distinct chronic lung diseases will be crucial for the development of novel, targeted therapeutic approaches.

The mission of the European Respiratory Society (ERS) is to alleviate suffering from respiratory disease and promote lung health through research, knowledge sharing, and medical and public education. In support of this mission, the ERS hosts the annual Lung Science Conference (LSC) in Estoril, Portugal, which brings together leading experts (basic scientists, physician scientists and clinicians alike) on distinct topics of relevance to respiratory medicine. In addition, the ERS is strongly committed to encourage, nurture and mentor future generations of world class respiratory scientists and clinicians. The LSC represents one of the main platforms to encourage debate and interaction between young doctoral and postdoctoral scientists with established investigators. In particular, this is facilitated by special mentoring sessions and the Young Investigator Competition, which enables younger delegates to present themselves and their work to established investigators.

Working around the clock, scientists at the Broad Institute of MIT and Harvard in Cambridge, Massachusetts can run about 2,000 COVID-19 tests per day. In places where testing is still scarce — which is to say much of the world — similar efforts can provide vital relief to public-health systems stretched to their limits. As they shutter their labs indefinitely, tens of thousands of scientists are volunteering to help the pandemic relief efforts in any way they can.


As labs shut down around the world, researchers are finding creative ways to donate their time, supplies and expertise.

The Army has a message for its retirees: Uncle Sam wants you to help fight the novel coronavirus.

A message sent by Defense Finance and Accounting Services, which processes and dispenses retiree pay, asked troops who had previously served in specific health care specialties to consider “re-joining the team” to address the current pandemic crisis. It’s signed by Lt. Gen. Thomas Seamands, deputy chief of staff for U.S. Army Personnel, G-1.

“We need to hear from you STAT!” reads the message, obtained by Military.com.

Circa 2016


Air pollution has a significant and pervasive impact on public health. According to the World Health Organization, it is now considered “the world’s largest single environmental health risk,” with more than three million people dying every year as a result. This is more than twice the number of people that die in vehicle accidents each year.

Health and safety are important to us. Just as we’ve designed Model S and Model X to avoid collisions or protect their occupants when one happens, we felt compelled to protect them against the statistically more relevant hazard of air pollution*. Inspired by the air filtration systems used in hospitals, clean rooms, and the space industry, we developed a HEPA filtration system capable of stripping the outside air of pollen, bacteria, and pollution before they enter the cabin and systematically scrubbing the air inside the cabin to eliminate any trace of these particles. The end result is a filtration system hundreds of times more efficient than standard automotive filters, capable of providing the driver and her passengers with the best possible cabin air quality no matter what is happening in the environment around them.

The air filtration system was put to the test in real-world environments from California freeways during rush hour, to smelly marshes, landfills, and cow pastures in the central valley of California, to major cities in China. We wanted to ensure that it captured fine particulate matter and gaseous pollutants, as well as bacteria, viruses, pollen and mold spores.

The intentional release of biological agents by belligerents or terrorists is a possibility that has recently attracted increased attention. Law enforcement agencies, military planners, public health officials, and clinicians are gaining an increasing awareness of this potential threat. From a military perspective, an important component of the protective pre-exposure armamentarium against this threat is immunization. In addition, certain vaccines are an accepted component of postexposure prophylaxis against potential bioterrorist threat agents. These vaccines might, therefore, be used to respond to a terrorist attack against civilians. We review the development of vaccines against 10 of the most credible biological threats.
