Biosafety and Its Prevention

Biosafety and Its Prevention

Biosecurity generally refers to the potential threats to the ecological environment and human health caused by the development and application of modern biotechnology, and a series of effective prevention and control measures. Based on the possible adverse effects of the development of biotechnology, the concept of biosecurity has been proposed. The so-called biosafety generally refers to the potential threats to the ecological environment and human health caused by the development and application of modern biotechnology, and a series of effective prevention and control measures.

In fact, where we can’t see it ~ the problem of biosecurity has always been there ~ the situation has turned serious since 2015. Biological threats have changed from incidental risks to real and persistent threats, threat sources have changed from single to diverse, threat boundaries have changed from being limited to a few areas to multi-regional and even global, and the impact of emergencies has expanded from public health to countries that affect countries. security and strategic interests. Traditional biosecurity issues are intertwined with non-traditional biosecurity issues, and external biological threats coexist with risks of internal regulatory loopholes.

1.Undercurrent superposition of traditional and new biological threat models

The global biological arms control governance is in a “chicken rib” state, and the possibility of carrying out biological attacks cannot be ruled out, but has increased. The biological warfare theory has taken shape, and the US Department of Defense has carried out 20YY biological warfare strategic research. In addition, new types of bioterrorism delivery methods continue to emerge, and tracking and tracing the source faces severe challenges, making it much more difficult to prevent bioterrorism attacks.

2.Emerging outbreaks of infectious diseases

In the past ten years, major new diseases such as influenza A (H1N1), highly pathogenic H5N1 avian influenza, highly pathogenic H7N9 avian influenza, fever with thrombocytopenia syndrome, Middle East respiratory syndrome, dengue fever, Ebola, and Zika have emerged successively. outbreak of infectious diseases. In the context of globalization, the epidemic spreads faster and more widely, even if it is far away from the other pole of the world, it is only a flight away. The Zika virus spread from Brazil to the world in less than a year since 2015, infecting about 500,000 people in 40 countries

3.The development of biotechnology leads to increased risks

Scientists have achieved “gene drives” for the first time in mammals. The gene drive system increases the inheritance probability of mutated genes from 50% to 99.5%, which can be used to eliminate specific biological species. With the development of gene editing and gene drive technology, the risk of genetic weapons is increasing. Compared with developed countries, developing countries lack the management and control systems and capabilities for the negative effects of biotechnology, and have obvious internal threats. At the same time, biotechnology has “stuck necks” in many strategic directions, and there are hidden external threats. . With economic and social development and the profound evolution of the international political and economic structure, developing countries are usually faced with more severe situations through layers of transmission and interaction from the outside to the inside and from the inside to the outside.

The closest to us may be the epidemic that all mankind is currently facing

In fact, the issue of biosecurity is an old problem plaguing mankind. With the development of society, especially the development of science and technology and the evolution of human warfare, biological warfare has experienced a process in which the threat of viruses has changed from “natural” to “mixed”, and from uncontrollable to gradually controllable. Notoriety. In ancient society, limited by the development level of productive forces and technical conditions, it was difficult for humans to develop viruses. Deadly viruses existing in nature became the main threat. At the same time, using these viruses to attack the enemy became a natural choice. The earliest biological warfare occurred in Europe more than 3,000 years ago. The Hittite Kingdom in Asia Minor sent people to put tularemia-infected sheep into the enemy country to infect the plague, in order to weaken the enemy army and eliminate the threat.

Of course, good biological experiments still play an important role in human progress. If you are worried about biological contamination caused by experimental items, then choose a high-quality biohazard container. Putting used experimental items and medical supplies in special biohazard containers and then centralized and unified treatment can effectively avoid biological contamination.
