Bioterrorism is terrorism involving the intentional release or dissemination of biological agents. These agents are bacteria, viruses, insects, fungi or toxins, and may be in a naturally occurring or a human-modified form, in much the same way as in biological warfare. Further, modern agribusiness is vulnerable to anti-agricultural attacks by terrorists, and such attacks can seriously damage economy as well as consumer confidence. The latter destructive activity is called agrobioterrorism and is a subtype of agro-terrorism.

Avian influenza, known informally as avian flu or bird flu, is a variety of influenza caused by viruses adapted to birds. The type with the greatest risk is highly pathogenic avian influenza (HPAI). Bird flu is similar to swine flu, dog flu, horse flu and human flu as an illness caused by strains of influenza viruses that have adapted to a specific host. Out of the three types of influenza viruses, influenza A virus is a zoonotic infection with a natural reservoir almost entirely in birds. Avian influenza, for most purposes, refers to the influenza A virus.
Influenza A virus subtype H5N1 (A/H5N1) is a subtype of the influenza A virus which can cause illness in humans and many other animal species. A bird-adapted strain of H5N1, called HPAI A(H5N1) for highly pathogenic avian influenza virus of type A of subtype H5N1, is the highly pathogenic causative agent of H5N1 flu, commonly known as avian influenza. It is enzootic in many bird populations, especially in Southeast Asia. One strain of HPAI A(H5N1) is spreading globally after first appearing in Asia. It is epizootic and panzootic, killing tens of millions of birds and spurring the culling of hundreds of millions of others to stem its spread. Many references to "bird flu" and H5N1 in the popular media refer to this strain.
Swine influenza is an infection caused by any one of several types of swine influenza viruses. Swine influenza virus (SIV) or swine-origin influenza virus (S-OIV) is any strain of the influenza family of viruses that is endemic in pigs. As of 2009, the known SIV strains include influenza C and the subtypes of influenza A known as H1N1, H1N2, H2N1, H3N1, H3N2, and H2N3.
An influenza pandemic is an epidemic of an influenza virus that spreads across a large region and infects a large proportion of the population. There have been five in the last 140 years, with the 1918 flu pandemic being the most severe; this pandemic is estimated to have been responsible for the deaths of 50–100 million people. The most recent, the 2009 swine flu pandemic, resulted in under a million deaths and is considered relatively mild. These pandemics occur irregularly.
The Biodefense and Pandemic Vaccine and Drug Development Act of 2005, nicknamed "Bioshield Two" and sponsored by Senator Richard Burr, aims shorten the pharmaceutical development process for new vaccines and drugs in case of a pandemic, and to protect vaccine makers and the pharmaceutical industry from legal liability for vaccine injuries. The proposed bill would create a new federal agency, the Biomedical Advanced Research and Development Agency (BARDA), that would act "as the single point of authority" to promote advanced research and development of drugs and vaccines in response to bioterrorism and natural disease outbreaks, while shielding the agency from public Freedom of Information Act (FOIA) requests. BARDA would be exempt from long-standing open records and meetings laws that apply to most government departments.
Transmission and infection of H5N1 from infected avian sources to humans has been a concern since the first documented case of human infection in 1997, due to the global spread of H5N1 that constitutes a pandemic threat.
The Public Readiness and Emergency Preparedness Act (PREPA), passed by the United States Congress and signed into law by President of the United States George W. Bush in December 2005, is a controversial tort liability shield intended to protect vaccine manufacturers from financial risk in the event of a declared public health emergency. The part of PREPA that actually affords such protection is now codified at 42 U.S.C. § 247d-6d. The act specifically affords to drug makers immunity from actions related to the manufacture, testing, development, distribution, administration and use of medical countermeasures against chemical, biological, radiological and nuclear agents of terrorism, epidemics, and pandemics. PREPA strengthens and consolidates the oversight of litigation against pharmaceutical companies under the purview of the secretary of Health and Human Services (HHS). PREPA provides $3.8 billion for pandemic influenza preparedness to protect public health in the case of a pandemic disease outbreak.
The social impact of H5N1 is the effect or influence of H5N1 in human society; especially the financial, political, social, and personal responses to both actual and predicted deaths in birds, humans, and other animals. Billions of dollars are being raised and spent to research H5N1 and prepare for a potential avian influenza pandemic. Over ten billion dollars have been lost and over two hundred million birds have been killed to try to contain H5N1. People have reacted by buying less chicken causing poultry sales and prices to fall. Many individuals have stockpiled supplies for a possible flu pandemic.
H5N1 clinical trials are clinical trials concerning H5N1 vaccines, which are intended to provide immunization to influenza A virus subtype H5N1. They are intended to discover pharmacological effects and identify any adverse reactions the vaccines may achieve in humans.
Human mortality from H5N1 or the human fatality ratio from H5N1 or the case-fatality rate of H5N1 refer to the ratio of the number of confirmed human deaths resulting from confirmed cases of transmission and infection of H5N1 to the number of those confirmed cases. For example, if there are 100 confirmed cases of humans infected with H5N1 and 10 die, then there is a 10% human fatality ratio. H5N1 flu is a concern due to the global spread of H5N1 that constitutes a pandemic threat. The majority of H5N1 flu cases have been reported in southeast and east Asia. The case-fatality rate is central to pandemic planning. Estimates of case-fatality (CF) rates for past influenza pandemics have ranged from to 2-3% for the 1918 pandemic to about 0.6% for the 1957 pandemic to 0.2% for the 1968 pandemic. As of 2008, the official World Health Organization estimate for the case-fatality rate for the outbreak of H5N1 avian influenza was approximately 60%. Public health officials in Ontario, Canada argue that the true case-fatality rate could be lower, pointing to studies suggesting it could be 14–33%, but warned that it was unlikely to be as low as the 0.1–0.4% rate that was built into many pandemic plans.
The Biomedical Advanced Research and Development Authority(BARDA) is a U.S. Department of Health and Human Services (HHS) office responsible for the procurement and development of medical countermeasures, principally against bioterrorism, including chemical, biological, radiological and nuclear (CBRN) threats, as well as pandemic influenza and emerging diseases. BARDA was established in 2006 through the Pandemic and All-Hazards Preparedness Act (PAHPA) and reports to the Office of the Assistant Secretary for Preparedness and Response (ASPR). The office manages Project BioShield, which funds the research, development and stockpiling of vaccines and treatments that the government could use during public health emergencies such as chemical, biological, radiological or nuclear (CBRN) attacks.
The Office of the Assistant Secretary for Preparedness and Response (ASPR) within the United States Department of Health and Human Services was created under the Pandemic and All Hazards Preparedness Act in the wake of Hurricane Katrina to lead the nation in preventing, preparing for, and responding to the adverse health effects of public health emergencies and disasters. ASPR focuses on preparedness planning and response; building federal emergency medical operational capabilities; countermeasures research, advance development, and procurement; and grants to strengthen the capabilities of hospitals and health care systems in public health emergencies and medical disasters. The office provides federal support, including medical professionals through ASPR’s National Disaster Medical System, to augment state and local capabilities during an emergency or disaster.
A H5N1 vaccine is an influenza vaccine intended to provide immunization to influenza A virus subtype H5N1.
The Zika Authorization Plan Act of 2016 was a bill introduced in the second session of the United States 114th Congress by Representative Curt Clawson (R-FL) on February 12, 2016. The bill was prompted by the Zika virus health scare and was aimed at reducing the spread of the virus.
The Pandemic and All-Hazards Preparedness and Advancing Innovation Act (PAHPAI) is legislation introduced and passed by the U.S. Congress in 2019 that aims to improve the nation's preparation and response to public health threats, including both natural threats and deliberate man-made threats.
The Coronavirus Preparedness and Response Supplemental Appropriations Act, 2020 is an act of Congress enacted on March 6, 2020. The legislation provided emergency supplemental appropriations of $8.3 billion in fiscal year 2020 to combat the spread of coronavirus disease 2019 (COVID-19) and counter the COVID-19 pandemic, particularly the COVID-19 pandemic in the United States. The legislation passed the House 415–2 on March 4 and the Senate 96–1 on March 5, 2020. The legislation received broad bipartisan support.
The World Health Organization is a leading organization involved in the global coordination for mitigating the COVID-19 pandemic, within the broader United Nations response to the pandemic caused by the emergence of severe acute respiratory syndrome coronavirus 2 in late 2019.
Planning and preparing for pandemics has happened in countries and international organizations. The World Health Organization writes recommendations and guidelines, though there is no sustained mechanism to review countries' preparedness for epidemics and their rapid response abilities. National action depends on national governments. In 2005–2006, prior to the 2009 swine flu pandemic and during the decade following it, the governments in the United States, France, UK, and others managed strategic health equipment stocks, but they often reduced stocks after the 2009 pandemic in order to reduce costs.
