Respiratory Illness Surveillance
COVID-19: MODERATE
RSV: LOW
Influenza A: VERY LOW
Influenza B: VERY LOW
Wastewater testing indicates an increase in COVID-19 levels. The solid lines on the graph show virus trends over the past year. SARS-CoV-2 (blue line), the virus that causes COVID-19, has gone up in recent weeks. Clinical COVID-19 cases reported at YKHC remain consistent with last week.
Influenza A (solid orange line), Influenza B (solid yellow line), and RSV (gray line) were not detected in wastewater. This week, we did have our first positive clinic test for RSV of the season, but still nothing for Flu A. RSV has not been detected in Anchorage wastewater, and Flu A levels there remain very low. Nationally, both RSV and Flu A activity are still low, but starting to rise. Around this time last year, we began to see an uptick in Flu A and RSV cases, so we will be monitoring these trends closely.
Other common respiratory pathogens detected in the region include Rhinovirus/Enterovirus, which often causes the common cold, and Mycoplama Pneumonia.
Mycoplama Pneumonia: We also seeing higher numbers of Mycoplama pneumonia, also known as “walking” pneumonia, which can cause prolonged cough, sometimes lasting several weeks. If you have had a cough lasting more than a week or a severe cough that occurs in sudden, please reach out to YKHC for evaluation and treatment.
Rhinovirus/enterovirus: The positivity rate for Rhinovirus/Enterovirus has increased in recent weeks, suggesting a rise in activity in the region. Rates peaked in the lower 48 states at the end of September but remain elevated there as well. These viruses are the most frequent causes of the common cold and are also a common viral trigger for asthma attacks. Most Rhinovirus infections cause no symptoms or mild symptoms.
If you develop any respiratory symptoms, please limit contact with others, especially elders, infants, and people with weakened immune systems. If you must be around others, wear a mask. And if you test positive for COVID-19 or Flu, talk with a healthcare provider about the highly effective antiviral treatments now available.
If You Are Sick from a Respiratory Virus:
- Limit your interactions for at least 24 hours after your symptoms improve and you have not had a fever without taking fever-reducing medication.
- For the first five days after symptoms have resolved, consider wearing a well-fitting mask, distancing from others, and getting tested. You may still be contagious.
YKHC Office of Environmental Heath's Testing of Bethel Wastewater
When people are ill from a viral infection, they release bits of virus into the wastewater when they use the toilet or wash their hands. The YKHC Office of Environmental Health consistently collects and evaluates Bethel wastewater to detect SARS-CoV-2, Influenza A and B, and RSV using sophisticated genomic testing techniques at our wastewater lab in Bethel.
Bits of virus in the wastewater include genetic material known as RNA or DNA. Our lab uses the same type of equipment as the hospital to detect genetic material specific for a particular virus. When we have a positive wastewater test, we know that the virus is in our community. Higher concentrations of the genetic material suggest there are more people with the virus in the community.
Wastewater testing does not tell us who is sick with the virus, but it does help us recognize when a virus enters the community and whether infections are going up or down.
Prevention of Respiratory Diseases
There are several things each of us can do protect ourselves and others from respiratory diseases.
Immunizations: Stay up to date with recommended immunizations! See information on this page and speak with your provider.
Don’t ignore your cough! Be on the lookout for symptoms that could be associated with pertussis. If you have had a cough lasting more than two weeks or a severe cough that occurs in sudden, uncontrollable bursts, especially if followed by vomiting, please reach out to YKHC for evaluation and treatment.
If you are sick from a respiratory virus:
- Limit your interactions for at least 24 hours after your symptoms improve and you have not had a fever without taking fever-reducing medication.
- For the first five days after symptoms have resolved, you may still be contagious. Consider wearing a mask and distancing from others.
Testing: Lab tests are widely available and can be readily accessed for common viruses, including COVID-19, flu, and RSV. At-home tests for SARS-CoV-2 are widely available and may be picked up from the security desk at the hospital. In villages, schedule a test at your local clinic.
If you test positive for COVID-19, call 907-543-6949, 543-6420, or your local clinic for more information.
Hygiene: Certain viruses can be spread through surfaces. Washing your hands often and cleaning and disinfecting surfaces can be helpful to prevent sickness.
Treatment: COVID-19 treatment can be highly effective if taken within 5 days of symptoms starting. People who received Paxlovid had a 75% reduction in the odds of death and 60% lower odds of hospitalization. Call 907-543-6949 or your local clinic for more information about accessing treatment.

Flu
Influenza (flu) is a contagious respiratory illness caused by influenza viruses that infect the nose, throat and lungs. The illness usually lasts 5-7 days, but symptoms can linger for 6 weeks.
Flu can cause:
- Dehydration: can cause imbalances of the salts in our blood
- Pneumonia: not bacterial requiring antibiotics, but fluid building in the lung tissue making it hard for the lungs to work well.
- Worsening of underlying illness like COPD, brochiectasis or other lung and heart conditions.
Flu is transmitted from person to person through droplets when we sneeze, cough, speak or sing and we can also pass it along by germs on our hands, so washing hands and masking if we’re sick are great ways to prevent from spreading the flu.
COVID-19
COVID-19 most often causes respiratory symptoms that can feel much like a cold, the flu, or pneumonia. But COVID-19 may attack more than your lungs and respiratory system. Other parts of your body may also be affected by the disease. Most people with COVID-19 have mild symptoms, but some people become severely ill. Some people, including those with minor or no symptoms, will develop post-COVID conditions, also called “Long COVID.”
Anyone infected with COVID-19 can spread it, even if they do not have symptoms.
Respiratory Syncytial Virus (RSV)
Respiratory syncytial virus (RSV) is a respiratory virus that causes cold-like symptoms.
Most people infected with RSV usually show symptoms within 4 to 6 days after getting infected. Symptoms of RSV infection usually include: runny nose, decrease in appetite, coughing, sneezing, fever and wheezing. These symptoms usually appear in stages and not all at once.
In very young infants with RSV, the only symptoms may be irritability, decreased activity or breathing difficulties.
Severe RSV infections include bronchiolitis (an inflammation of the small airways in the lung) and pneumonia. RSV can also make chronic health problems worse. For example, people with asthma may experience asthma attacks as a result of RSV infection, and people with congestive heart failure may experience more severe symptoms triggered by RSV.
