Wastewater monitoring is a valuable, efficient, and robust tool that public health officials can use to guide public health decision making across the nation. When we turn on the tap or flush the toilet, we often don’t think about where all that water goes. Wastewater, the used water from our homes, schools, and businesses, holds valuable information about the health of our community. Wastewater monitoring can help cities manage wastewater effectively and also creates a safer, healthier, and more responsive living environment for their communities. This blog takes a closer look at five...

Fluoride has been in the news recently with some people questioning the worth of adding this vital mineral to the water supplies in the United States. Fluoride repairs and prevents damage to teeth caused by bacteria in the mouth. Bacteria in the mouth produce acid when a person eats or drinks. The acid dissolves minerals in a tooth's surface, making the tooth weaker and open to cavities. Fluoride replaces the minerals lost from a tooth due to acid breakdown. Some fluoride can replace minerals in the tooth surface, making the outer enamel layer harder to dissolve. Fluoride also may...

Many people assume that ingesting cannabis — whether through edibles, oils, or tinctures — eliminates the cardiovascular risks associated with smoking it. While it's true that edibles avoid the harmful byproducts of combustion (such as carbon monoxide and tar), ingested cannabis still carries significant heart health risks due to the effects of tetrahydrocannabinol (THC), its main psychoactive compound. When THC is absorbed through the digestive system, it can cause substantial increases in heart rate and blood pressure — sometimes more dramatically than when cannabis is smoked or...

Nitrous oxide, also sometimes known as “laughing gas,” is used in medicine for its sedative and anesthetic (pain prevention) properties. Joseph Priestley, an English chemist, and multidisciplinary scholar, first synthesized nitrous oxide, which has the chemical formula N2O, in 1772. After Priestley’s initial discovery of this substance, fellow chemist Humphry Davy performed various tests on the substance, including breathing the gas alone, with oxygen, and with air. Through this testing, it became clear that nitrous oxide had psychogenic properties, including as a sedative and...

Vaccination is one of the best ways to prevent diseases. Over the past 50 years, essential vaccines saved at least 154 million lives (1). During the same period, vaccination has reduced infant deaths by 40%. Together with governments, vaccine manufacturers, scientists and medical experts, WHO's vaccine safety program is constantly helping monitor the safety of vaccines. This helps ensure that vaccines are safe for you and your family. In the United States, a number of safeguards are required by law to help ensure that the vaccines we receive are safe. Because vaccines are given to millions...

Whooping cough, also known as pertussis, is a highly contagious respiratory infection caused by the bacteria Bordetella pertussis. It's characterized by severe, persistent coughing fits, often ending with a high-pitched "whoop" sound. The disease can be very serious, especially for infants, and is preventable through vaccination. Whooping cough is an illness that can spread easily. It's also called pertussis. An infection with bacteria causes it. Many people with the illness get a serious hacking cough. Breathing in after coughing often causes a high-pitched noise that sounds like a...

Vaccines help prevent infection by preparing the body to fight foreign invaders (such as bacteria, viruses, or other pathogens). All vaccines introduce into the body a harmless piece of a particular bacteria or virus, triggering an immune response. Most vaccines contain a weakened or dead bacteria or virus. However, scientists have developed a new type of vaccine that uses a molecule called messenger RNA (mRNA) rather than part of an actual bacteria or virus. Messenger RNA is a type of RNA that is necessary for protein production. Once cells finish making a protein, they quickly break down the mRNA. mRNA from vaccines does not enter the nucleus and does not alter DNA.
mRNA vaccines work by introducing a piece of mRNA that corresponds to a viral protein, usually a small piece of a protein found on the virus’s outer membrane. (Individuals who get an mRNA vaccine are not exposed to the virus, nor can they become infected with the virus by the vaccine.) By using this mRNA, cells can produce the viral protein. As part of a normal immune response, the immune system recognizes that the protein is foreign and produces specialized proteins called antibodies. Antibodies help protect the body against infection by recognizing individual viruses or other pathogens, attaching to them, and marking the pathogens for destruction. Once produced, antibodies remain in the body, even after the body has rid itself of the pathogen, so that the immune system can quickly respond if exposed again. If a person is exposed to a virus after receiving mRNA vaccination for it, antibodies can quickly recognize it, attach to it, and mark it for destruction before it can cause serious illness.
Like all vaccines in the United States, mRNA vaccines require authorization or approval from the Food and Drug Administration (FDA) before they can be used. Currently vaccines for COVID-19, the disease caused by the SARS-CoV-2 coronavirus, are the only authorized or approved mRNA vaccines. These vaccines use mRNA that directs cells to produce copies of a protein on the outside of the coronavirus known as the “spike protein”. Researchers are studying how mRNA might be used to develop vaccines for additional diseases. (credits: Medline Plus)
