Public Health

IDSA members are leaders in addressing many types of infectious diseases-related public health concerns such as measles, the opioid crisis, vaccine awareness; outbreaks such as Ebola and Zika; and the potential health consequences of natural disasters such as hurricanes. Find the latest information on these topics and how IDSA and its members are involved in protecting the public’s health.

Patient Stories

Many patients and their families have suffered the debilitating effects of antibiotic-resistant infections. Indeed, many patients have lost their lives due to these infections.

Facts About ID

Infectious diseases are caused by microscopic organisms that penetrate the body’s natural barriers and multiply to create symptoms that can range from mild to deadly.

Antimicrobial Resistance

Antibiotics, antivirals, and other antimicrobials have saved millions of lives worldwide, but these drugs are losing their effectiveness because of antimicrobial resistance.


Ebola Virus Disease (EVD) is a rare and deadly disease in people and nonhuman primates. Infectious diseases physicians and scientists are on the front lines providing care and seeking cures. IDSA tracks outbreaks and provides information and resources.

Hepatitis C

Millions of Americans are infected with HCV and have chronic liver disease as a result. New direct-acting antivirals have the potential to cure most patients with HCV. IDSA provides up-to-date guidance on the best treatment options that keep pace with rapid drug development.

Hurricane Resources

Natural disasters such as hurricanes with widespread flooding can increase the risk of spread of infectious disease outbreaks. Hand hygiene, clean water, and access to medications are essential to preventing and limiting the spread of infectious diseases.


Immunization is one of the most important things you can do to protect yourself, your family, and your community from infectious diseases.


Influenza (flu) is a viral infection that can be serious and even fatal. IDSA focuses on both seasonal and pandemic flu.

Lyme Disease

Lyme disease is caused by bacteria called Borrelia burgdorferi that is only transmitted to humans when they are bitten by an infected tick.

Opioid Epidemic

The national opioid crisis is fueling a rise in infectious diseases including HIV, viral hepatitis and certain bacterial infections. ID and HIV clinicians on the frontlines of the opioid epidemic report that 25 to 50 percent of their inpatient consultations are due to infections among patients who inject drugs.


Many people infected with Zika virus will only have mild symptoms or none, at all. Most don’t get sick enough to go to the hospital, and they very rarely die of Zika. However, infection during pregnancy can cause a birth defect of the brain called microcephaly and other severe brain defects.


Measles can cause health complications that include pneumonia and encephalitis. The virus is highly contagious; 95 percent of people must be vaccinated with two doses to protect those who aren't.
