The Tragedy of Liberal Democratic Governance in the Face of Global Threats

In hindsight, the early response of liberal governments to the SARS-CoV-2 pandemic was chaotic and generally inefficient. Though one might be tempted to attribute these failures to the incompetence of certain political decision-makers, we propose another explanation. Global threats require a coordinated international response, which is only possible if the threat is perceived in the same way by all, and if government priorities are similar. The effectiveness of the response also relies on massive adhesion of citizens to the measures imposed, which in turn requires trust in government. Our hypothesis is that certain fundamental features of liberalism complicate such global and collective responses: neutrality of the state and primacy of the individual over collective society. Liberalism considers that institutions and public policy must not be designed to favor any specific conception of the common good. That which is best for all is usually determined by a "competition of opinions," which frequently leads to scientific expertise being considered as only one opinion among many. Liberalism also imposes strict respect for individual freedoms and private interests and tends to reject any form of collectivism or dictate imposed by the common good. In order to solve these structural problems and improve society's management of global threats, we make several proposals, such as the introduction of a minimal and consensual definition of the common good and the promotion of a health policy guided by One Health-like concepts. Overall, our analysis suggests that because political ideologies provide their own definitions of the common good and the place of scientific knowledge in the governance process and can thus affect the response to global threats, they should be urgently taken into consideration by public health experts.

Effect of Live Poultry Market Closure on Avian Influenza A(H7N9) Virus Activity in Guangzhou, China, 2014

Temporary closure and disinfection can rapidly reduce levels of infectious virus in these settings.

We assessed the effect of closing live poultry markets in China on influenza A(H7N9) virus detection and viability. Intensive sampling was carried out before, during, and after a 2-week citywide market closure; the markets were cleaned and disinfected at the beginning of the closure period. Swab samples were collected at different sites within the markets and tested for H7N9 by real-time reverse transcription PCR and culture. During the closure, H7N9 viral RNA detection and isolation rates in retail markets decreased by 79% (95% CI 64%–88%) and 92% (95% CI 58%–98%), respectively. However, viable H7N9 virus could be cultured from wastewater samples collected up to 2 days after the market closure began. Our findings indicates that poultry workers and the general population are constantly exposed to H7N9 virus at these markets and that market closure and disinfection rapidly reduces the amount of viable virus.

Lack of middle East respiratory syndrome coronavirus transmission from infected camels

To determine risk for Middle East respiratory syndrome coronavirus transmission from camels to humans, we tested serum from 191 persons with various levels of exposure to an infected dromedary herd. We found no serologic evidence of human infection, suggesting that zoonotic transmission of this virus from dromedaries is rare.

H5N1 highly pathogenic avian influenza in Indonesia: retrospective considerations

Indonesia is one of the five countries where highly pathogenic avian influenza viruses of the H5N1 subtype (H5N1 HPAI) remain endemic in poultry. Importantly, it is one of the countries where the virus causes human infections. WHO data indicate that as of 2 May 2012, 189 human cases of Influenza A (H5N1) had been reported in Indonesia, with 157 human deaths. These human cases included a small number in which limited human-to-human transmission could have occurred. Hence, there remains a critical need in Indonesia for a more effective One Health approach to the control and prevention of this disease in people and in poultry. This chapter explores a number of aspects of the evolution of this disease in Indonesia, the virus that causes it and the control and preventive measures introduced, focusing on the successes and shortcomings of veterinary and One Health approaches. Indonesia provides many examples of situations where this latter approach has been successful, and others where further work is needed to maximize the benefits from coordinated responses to this disease leading to effective management of the risk to human health.
