COVID-19

COVID-19 is a viral respiratory illness spread from person to person that causes symptoms such as fever, fatigue, shortness of breath, and cough. In serious cases, it can lead to respiratory failure, hospitalization, and death. There are many risk factors for severe COVID-19, including obesity, pregnancy, and certain chronic lung diseases. COVID-19 can be prevented by several prevention methods such as staying home from school and work when ill.

General Symptoms:	Fever or chills Fatigue Shortness of breath Cough Muscle or body Aches Congestion or runny nose New loss of taste or smell Headache Sore throat
Serious Outcomes:	Hospitalization Respiratory failure or require a ventilator to help them breathe Intensive care Long COVID Death
Risk:	Older adults, those aged 50 years and older Immunocompromised or weakened immune system Underlying health conditions such as: Obesity Chronic lung diseases such as COPD and pulmonary embolism Cancer Chronic kidney, liver, heart diseases Asthma Diabetes types 1 and 2 Disabilities such as Down Syndrome Dementia Pregnancy Smoking (current and former)
How it spreads:	Contact with respiratory droplets from an infected person when they are talking, sneezing, or coughing Contact with a surface with the COVID-19 virus on it and then touches their nose or mouth.
Prevention:	Avoiding contact with people who might be ill Wearing masks or respirators Improving ventilation and filtration by bringing in outdoor air, using HEPA filters, and turning on exhaust fans or spending time outside when possible Staying home from school or work if you are feeling ill

The General Appropriations Act, House Bill 1 (H.B. 1), Article II, Rider 40, is effective September 1, 2023. Rider 40 prohibits the Department of State Health Services (DSHS) from using appropriated funds to promote or advertise COVID-19 vaccinations.

How it spreads:	Breathing in droplets from an infected person’s sneeze or cough. Some infected children won’t show symptoms but can still spread the disease.
Prevention:	Pneumococcal vaccine

Learn more on the CDC’s pneumococcal page or DSHS Immunizations | Pneumococcal Disease.

Polio

Polio is a serious disease that attacks the nervous system and can lead to lifelong paralysis or death. There is no cure or specific treatment, so prevention through vaccination gives children the best protection without the risk of serious complications of the disease.

General Symptoms:	Flu-like symptoms for some people, but most won’t have any.
Serious Outcomes:	Lifelong weakness or paralysis of arms and/or legs. New muscle pain, weakness or paralysis after being infected; this can happen 15 to 40 years later. Death
Risk:	Very contagious.
How it spreads:	Germs from an infected person’s stool (poop) get into someone’s mouth via dirty hands, objects or food. This can happen easily from a tiny germ on a doorknob or dirty diaper. Breathing in droplets from an infected person’s sneeze or cough.
Prevention:	Polio vaccine

Learn more on the CDC’s polio page.

Rabies

Rabies is a virus that is transmitted by wildlife or unvaccinated domesticated animals that affects the central nervous system. While it should be noted that not all animals have rabies, any suspected case of rabies should be taken seriously and immediate precautions should be taken. Proper rabies treatment if exposed and vaccinating domesticated animals can prevent the disease.

General Symptoms:	First symptoms of rabies may be similar to the flu, including weakness or discomfort, fever, or headache. There also may be discomfort, prickling, or an itching sensation at the site of the bite. Symptoms can progress into neurologic symptoms such as anxiety, confusion, and agitation. Further progression would include abnormal behavior, hallucinations, hydrophobia (fear of water), and insomnia.
Serious Outcomes:	Once clinical signs of rabies appear, the disease is nearly always fatal.
Risk:	Majority of people in the United States have a low risk of coming into contact with rabies. Some people are at a higher risk due to working directly with animals that could have rabies or those who travel to parts of the world where rabies is common and access to medical care is limited. Children are often at greatest risk due to being more likely to be bitten by dogs and have multiple bites in high-risk sites on the body.
How it spreads:	Rabies is often spread by the bite of a rabid animal or through saliva of a rabid animal being introduced into a fresh scratch or similar break in the skin. Animals such as bats, coyotes, foxes, racoons, and skunks are at higher risk for rabies and thus are more likely to transmit the disease. These animals can then encounter domestic animals such as household cats and dogs.
Prevention:	Avoiding handling wild animals and dogs and cats you do not know, especially if they appear to be sick. Getting vaccinated before exposure to rabies if you work directly with animals that could have rabies or travel to parts of the world where rabies is common and access to medical care is limited. Getting rabies vaccination and immunoglobulin treatment after being exposed to rabies. Vaccinating domesticated animals such as dogs and cats Quarantining domestic animals such as dogs and cats who are involved in biting incidents or suspected of being rabid should be confined in isolation under veterinary supervision for at least 10 days.

Rotavirus

Rotavirus mostly affects babies and young children, causing severe diarrhea and vomiting. More severe cases can lead to serious dehydration. There is no cure for rotavirus, so prevention through vaccination gives children the best protection without the risk of serious complications of the disease. The rotavirus vaccine is given through drops in the mouth, not by a shot.

General Symptoms:	Fever Vomiting Stomach pain Diarrhea
Serious Outcomes:	Not eating and drinking while sick. Dehydration, which can be deadly for babies and young children.
Risk:	Highly contagious.
How it spreads:	Germs from an infected person’s stool (poop) get into someone’s mouth via dirty hands, objects or food. This can happen easily from a tiny germ on a doorknob or dirty diaper. The virus can survive on surfaces for several days.
Prevention:	Rotavirus vaccine

Learn more on the CDC’s rotavirus page.

Respiratory Syncytial Virus (RSV)

Respiratory Syncytial virus (RSV) is a respiratory illness, that while mild for most people, can cause severe illness in infants, toddlers, and adults aged 60 years and older. Almost all children will have had an RSV infection by their second birthday. Symptoms can be different between children younger than 2 and those older, but it typically presents with symptoms similar to other respiratory infections. It can spread through coughing and sneezing or touching contaminated services. RSV can be prevented by new immunization products for infants, pregnant women, and adults aged 60 and older, staying home from work and school when ill, and following good hand hygiene, and covering sneezing and coughs.

General Symptoms:	Low grade fever Congested or runny nose Sore throat Cough Headache Fatigue Wheezing Symptoms for young infants may present as irritability, decreased activity, and breathing difficulties.
Serious Outcomes:	Worsening croupy cough Unusually rapid breathing Difficulty breathing Bluish color of lips or fingernails indicating low blood oxygen levels Bronchiolitis Pneumonia Middle ear infections Respiratory failure Hospitalization
Risk:	Older adults Infants up to 12 months, especially 6 months and younger Premature infants Children and adults with weakened immune systems Children younger than 2 years with chronic lung disease or congenital heart disease Adults with chronic heart and lung disease Adults living in nursing homes or long-term care facilities Children who have neuromuscular disorders
How it spreads:	Contact with respiratory droplets from an infected person when they are talking, sneezing, or coughing Direct contact with someone who is infected with RSV Contact with a surface with the RSV on it and then touches their nose or mouth.
Prevention:	Getting immunized against RSV for infants, some higher risk children, pregnant women, and adults aged 60 years or older. Staying home from school and work when ill Washing your hands and avoiding touching your face with unwashed hands Covering your nose and mouth when coughing and sneezing with a tissue or sleeve Cleaning frequently touched surfaces Avoiding close contact with others who might be ill

Learn more on the CDC's RSV page.

Rubella

Rubella, often called German measles, is a viral disease that is usually mild in children. Complications occur more often in adults. Women who plan to become pregnant should get the MMR vaccine. Infection during pregnancy can cause miscarriage or birth defects including deafness, blindness, intellectual disability, heart defects and liver or spleen damage. The MMR vaccine is the best way to give children and those around them protection from rubella without the risk of serious complications of the disease.

General Symptoms:	Mild fever Rash starting on face that spreads to rest of body Older children and adults may also have: Swollen glands Cough, runny nose and red or swollen eyes Aching joints (especially in young women)
Serious Outcomes:	Brain infections Bleeding problems Miscarriage and birth defects
Risk:	Highly contagious.
How it spreads:	Breathing in droplets from the sneeze or cough of an infected person. Often infected people don’t have symptoms but can still spread the disease.
Prevention:	Measles, mumps and rubella combo vaccine (MMR)

Learn more on the CDC’s rubella page or DSHS Vaccine Preventable Disease Conditions | Rubella (German Measles).

Tetanus

Tetanus is a serious disease caused by bacteria that live in soil, dust and manure. Also known as “lockjaw,” tetanus causes painful muscle contractions, often starting in the jaw and neck, that can make it hard to open the mouth or swallow. Tetanus can lead to death. The DTaP vaccine is the best way to give children protection from tetanus without the risk of serious complications of the disease.

General Symptoms:	Jaw cramping Sudden, involuntary muscle spasms, often in the stomach Painful muscles and stiffness all over the body Trouble swallowing Seizures Headache Fever and sweating Changes in blood pressure and heart rate
Serious Outcomes:	Breathing problems Muscle spasms, which can be strong enough to break a child’s spine or other bones Paralysis Death
Risk:	Not transmitted from person to person
How it spreads:	Bacteria enter the body through breaks in the skin such as punctures, cuts, sores, burns and animal bites.
Prevention:	Diphtheria, Tetanus and Pertussis Combo vaccine (DTaP)

Learn more on the CDC’s tetanus page or DSHS Vaccine Preventable Disease Conditions | Tetanus.

Whooping Cough

Pertussis, also known as whooping cough, is a serious respiratory illness that can cause violent coughing fits. Gasping for breath after a coughing fit can sometimes cause a “whooping” sound, but not all children make this noise. These coughing fits can last 10 weeks or longer and they can return the next time the child has a respiratory illness. Babies can easily catch whooping cough from family members who don’t know they have it. Half of all whooping cough deaths are among babies less than 2 months old, who are too young to get vaccinated. By getting the DTaP vaccine, pregnant women can pass temporary protection to their babies. Once babies are old enough to be vaccinated, the DTaP vaccine is the best way to give them protection from whooping cough without the risk of serious complications of the disease.

General Symptoms:	Runny nose Coughing Sneezing Low-grade fever Mild cough (not in babies)
Serious Outcomes:	Difficulty breathing, eating, drinking or sleeping Violent coughing fits that may cause vomiting Gasping for breath after a coughing fit, causing a “whooping” sound Babies may: Gag, gasp, or stop breathing Be hospitalized Develop pneumonia (a serious lung infection) Have seizures Turn blue or purple from a lack of oxygen Suffer brain damage
Risk:	Highly contagious
How it spreads:	Breathing in droplets from an infected person’s sneeze or cough.
Prevention:	Diphtheria, Tetanus and Pertussis Combo vaccine (DTaP)

Learn more on the CDC’s whooping cough page or DSHS Vaccine Preventable Disease Conditions | Pertussis (Whooping Cough).

Yellow Fever

Yellow Fever is an viral illness transmitted to humans by the bites of certain species of mosquitoes in parts of Africa and Central America. Symptoms such as fever, chills, and headache typically develop 3-6 days after infection. While many people may have mild symptoms, 12% of people will develop serious illness. Yellow fever can be prevented by getting vaccinated or preventing mosquito bites when traveling to areas where yellow fever occurs. To check if a yellow fever vaccine is recommended or required for your travel location, see CDC’s website on Traveler’s Health located here: Yellow Fever | Disease Directory | Travelers' Health | CDC

General Symptoms:	Fever Chills Loss of appetite Headache Nausea Vomiting Muscle and backache
Serious Outcomes:	High fever Jaundice (yellowing of the skin or eyes) Bleeding Shock Organ Failure
Risk:	People who are living or travelling to certain parts of Africa and South America where yellow fever is seen in humans or monkeys and there are mosquitos to spread the virus
How it spreads:	Transmitted to people through the bite of an infected mosquito that become infected through contact with infected humans or monkeys
Prevention:	Preventing mosquito bites through repellents, wearing long-sleeved shirts and pants, and keeping mosquitoes out of your lodging and sleeping. Controlling mosquitoes indoors and outdoors through screens on windows and doors, using air conditioning, and preventing any standing water in the environment where mosquitos could lay eggs in or near Getting vaccinated before traveling or living in areas at risk in Africa and South America
