According to World Health Organization statistics, 1.7 million people became newly infected with HIV in 2019. Daily PrEP (pre-exposure prophylaxis) with the combination of emtricitabine (FTC) and tenofovir (TAF) or tenofovir disoproxil fumarate (TDF) is highly effective in preventing HIV infection. However, many people can find it challenging to adhere to a daily pill schedule and thus, may not fully benefit from PrEP.

Homocystinuria (HCU), a group of inherited disorders, causes symptoms ranging from failure to thrive and developmental delays in infants or young children to abnormal blood clots with onset in adults.1 Approximately 1 in 200,000 to 335,000 people have HCU globally.2

Streptococcus pneumoniae is the leading cause of community-acquired pneumonia and is also a frequent cause of bloodstream, brain and spinal cord, ear, and sinus infections. According to 2015 CDC data, an estimated 900,000 Americans get pneumococcal pneumonia each year and approximately 5-7% die from it annually. Accurate diagnosis and early treatment are important for improving patient outcomes.

Streptococcus pneumoniae, or pneumococcus, is a type of bacteria that causes pneumococcal disease. Pneumococcal infections can range from ear and sinus infections to pneumonia and bloodstream infections. Children younger than 2 years old and adults 65 years or older are among those most at risk for disease.

Influenza B causes significant morbidity and mortality yearly around the world. There are two genetically and antigenically distinct lineages of influenza B that are known to co-circulate within the same influenza season. Currently, the trivalent influenza vaccine only has one influenza B lineage component.

According to the World Health Organization (WHO), rabies causes greater than 59,000 deaths every year in over 150 countries as of 2017. A rapid and reliable diagnostic test for rabies is critical for prophylaxis considerations in humans bitten by animals as well as for basic surveillance and animal rabies control programs. The World Organization of Animal Health (OIE) and WHO Expert Committee on Rabies recently approved the direct rapid immunohistochemical test (DRIT) for rabies diagnostics.

This invention relates to a diagnostic kit for assessing exposure to or infection by a koala retrovirus. The kit consists of specific primers and probes for the detection of three distinct subtypes of infectious koala retrovirus and may be useful in various species, including humans, primates, and koalas.

Military uniforms and mosquito nets are treated with permethrin, a repellent and insecticide used for personal protection against biting flies, mosquitoes, and other disease-carrying insects. Vector-borne diseases such as malaria, leishmaniasis (a parasitic infection spread by sandflies), Zika virus, West Nile virus, Lyme disease, and more can be diminished if treated nets or clothing containing the proper amount of permethrin are utilized. Washing and wear depletes the insecticide on the material, eventually rendering it ineffective.

Lead (Pb) exposure can cause serious health concerns including abdominal pain, headaches, loss of appetite, memory loss, weakness, and other symptoms. Lead residues on human skin, especially on the hands of workers can be a significant health risk since such residues may be ingested during normal activities (e.g. eating, drinking, and smoking). A key component to reducing lead exposure is being able to identify areas of lead contamination.

Exposure to lead (Pb) has long posed serious health risks. Ingestion of lead from skin exposure can adversely impact every organ in the body; the kidneys, blood, nervous, and reproductive systems are most affected. Washing skin with soap and water is not sufficient to remove lead residues. To prevent adverse impacts from Pb exposure, exposed individuals need cleaning methods that will effectively remove Pb ions from the skin to less than the limit of identification (i.e., 10 µg or less).
