Clear All Filters ×H1N1 Flu (Swine Flu)
Swine flu is an infection caused by a virus. It's named for a virus that pigs can get. People do not normally get swine flu, but human infections can and do happen. In 2009 a strain of swine flu called H1N1 infected many people around the world. The virus is contagious and can spread from human to human. Symptoms of swine flu in people are similar to the symptoms of regular human flu and include fever, cough, sore throat, body aches, headache, chills and fatigue. There are antiviral medicines you can take to prevent or treat swine flu. There is a vaccine available to protect against swine flu.
HIV
What is HIV? HIV stands for human immunodeficiency virus. HIV harms your immune system by destroying a type of white blood cell that helps your body fight infection. This puts you at risk for other infections and diseases. What is AIDS? AIDS stands for acquired immunodeficiency syndrome. It is the final stage of infection with HIV. It happens when the body's immune system is badly damaged because of the virus. Not everyone with HIV develops AIDS. How does HIV spread? HIV is spread through certain body fluids from a person who has HIV. This can happen: By having unprotected vaginal or anal sex with a person who has HIV.
HIV - Congenital
Cataloged under federal diagnostic code B20 in Infections & Antivirals, HIV - Congenital (also termed Congenital or Born with) requires bacterial/fungal culture with in HIV - Congenital (B20: antimicrobial susceptibility testing) so specialists can calibrate treatment intensity against C-Reactive Protein / in HIV - Congenital (B20: Procalcitonin) benchmarks.
HIV Medicines
What is HIV? HIV stands for human immunodeficiency virus. It harms your immune system by destroying CD4 cells. These are a type of white blood cells that fight infection. The loss of these cells makes it hard for your body to fight off infections and certain HIV-related cancers. Without treatment, HIV can gradually destroy the immune system and advance to AIDS. AIDS stands for acquired immunodeficiency syndrome. It is the final stage of infection with HIV. Not everyone with HIV develops AIDS. What is antiretroviral therapy (ART)? The treatment of HIV with medicines is called antiretroviral therapy (ART). It involves taking a combination of medicines every day.
HIV and Infections
Having HIV/AIDS weakens your body's immune system. It destroys the white blood cells that fight infection. This puts you at risk for opportunistic infections (OIs). OIs are serious infections that take advantage of your weak immune system. These infections are less common and less severe in healthy people.
HIV exposure
Within Bacterial, Viral & Fungal Infections practice, HIV exposure (ICD-10 Z20.6) is stratified through rapid antigen/NAAT PCR in HIV exposure (Z20.6: diagnostics), pairing targeted symptom control with longitudinal Targeted PCR / in HIV exposure (Z20.6: Culture & Sensitivity) surveillance.
HIV in Women
What is HIV? HIV stands for human immunodeficiency virus. It harms your immune system by destroying a type of white blood cell that helps your body fight infection. This puts you at risk for other infections and diseases. How does HIV spread? HIV can spread in different ways: By having unprotected vaginal or anal sex with a person who has HIV. "Unprotected" means not using condoms or medicine to treat or prevent HIV. This is the most common way it spreads. Anal sex is the riskiest type of sex for getting or spreading HIV. The rectum's lining is thin and may allow HIV to enter the body during anal sex.
HIV positive
Clinical triage of HIV positive (Z21) in Infections & Antivirals relies on bacterial/fungal culture with in HIV positive (Z21: antimicrobial susceptibility testing), guiding step-wise therapeutic adjustments toward C-Reactive Protein / in HIV positive (Z21: Procalcitonin) (Resolution to baseline (Z21)).
HIV: PrEP and PEP
What are PrEP and PEP? PrEP and PEP are medicines to prevent HIV . Each type is used in a different situation: PrEP stands for pre-exposure prophylaxis. It is for people who don't already have HIV but are at risk of getting it. PrEP is medicine that can reduce this risk. You can take it as a pill every day or as an injection every two or six months. With PrEP, if you do get exposed to HIV, the medicine can stop HIV from taking hold and spreading throughout your body. PEP stands for post-exposure prophylaxis. PEP is for people who have possibly been exposed to HIV. It is only for emergency situations. PEP must be started within 72 hours after a possible exposure to HIV.
Haemophilus Infections
Haemophilus is the name of a group of bacteria. There are several types of Haemophilus. They can cause different types of illnesses involving breathing, bones and joints, and the nervous system. One common type, Hib (Haemophilus influenzae type b), causes serious disease. It usually strikes children under 5 years old. Your child can get Hib disease by being around other children or adults who may have the bacteria and not know it. The germs spread from person to person. If the germs stay in the child's nose and throat, the child probably will not get sick.
Hantavirus Infections
Hantavirus pulmonary syndrome (HPS) is a rare viral infection caused by several strains of the hantavirus. It is spread by mice and rats. They shed the virus in their urine, droppings, and saliva. Tiny droplets with the virus can enter the air. You can get the disease if you breathe infected air or come into contact with rodents or their urine or droppings. Most of the time, you can't get the virus from another person. But one strain of the virus found in South America, called the Andes virus, spreads through close contact with someone who has the virus.
Helicobacter pylori infection
Physicians managing Helicobacter pylori infection (A04.8; Bacterial, Viral & Fungal Infections) utilize bacterial/fungal culture with in Helicobacter pylori infection (A04.8: antimicrobial susceptibility testing) and objective Complete Blood Count in Helicobacter pylori infection (A04.8: (WBC & Differential)) targets (WBC 4.0 – 10.0 x10^3/uL (A04.8)) to prevent progression and functional morbidity.

Hemorrhagic Fevers
Viral hemorrhagic fevers (VHFs) are a group of illnesses caused by four families of viruses. These include the Ebola and Marburg, Lassa fever, and yellow fever viruses. VHFs have common features: they affect many organs, they damage the blood vessels, and they affect the body's ability to regulate itself. Some VHFs cause mild disease, but some, like Ebola or Marburg, cause severe disease and death. VHFs are found around the world. Specific diseases are usually limited to areas where the animals that carry them live. For example, Lassa fever is limited to rural areas of West Africa where rats and mice carry the virus.
Herpes Simplex
Herpes is an infection that is caused by a herpes simplex virus (HSV). Oral herpes causes cold sores around the mouth or face. Genital herpes affects the genitals, buttocks or anal area. Genital herpes is a sexually transmitted infection (STI). It affects the genitals, buttocks or anal area. Other herpes infections can affect the eyes, skin, or other parts of the body. The virus can be dangerous in newborn babies or in people with weak immune systems. There are two types of HSV: HSV type 1 most commonly causes cold sores. It can also cause genital herpes. HSV type 2 is the usual cause of genital herpes, but it also can infect the mouth.

Histoplasmosis
What is histoplasmosis? Histoplasmosis is an infection caused by a fungus called Histoplasma . This fungus is common in the central and eastern United States, especially around the Ohio and Mississippi River valleys. It can also be found in parts of Central and South America, Africa, Asia, and Australia. It lives in the environment, especially in soil that contains large amounts of bat or bird droppings (poop). How do you get histoplasmosis? You get histoplasmosis by breathing in Histoplasma fungal spores from the air. It usually happens after you have been doing an activity that disturbs the soil, such as farming, construction, and landscaping.
Homelessness and Health
What are the causes of homelessness? Each night, hundreds of thousands of people experience homelessness in the United States. Some of these people experience chronic homelessness, while others have temporarily lost their shelter. The reasons why they are homelessness are complex. They can include a combination of factors such as: Poverty Unemployment Lack of affordable housing Mental and substance use disorders Trauma and violence Intimate partner violence Justice-system involvement Sudden serious illness Divorce Death of a partner or parent Disabilities What is the link between homelessness and health? Poor health can contribute to homelessness.
