What is COVID-19?

COVID-19 is an illness caused by a new coronavirus that emerged in late 2019. This virus impacts people of all ages, however symptoms can vary widely and are similar to those of other common illnesses.

Why are there different variants of COVID-19?

Viruses constantly mutate and change. Some changes are irrelevant, while other changes make the virus weaker. However, some changes make the virus easier to spread or potentially more potent, causing more severe disease. The CDC and other infectious disease specialists closely monitor the emergence of variants such as Delta and Omicron and alert the public if a variant poses a significant risk to public health and can be easily transmitted from person to person.

Six tips for how families can manage Omicron

What are the symptoms of COVID-19?

People with COVID-19 may have mild, moderate, or severe symptoms. A person with any of these symptoms could have COVID-19:

  • fever or chills
  • cough
  • shortness of breath or difficulty breathing
  • fatigue
  • muscle or body aches
  • headache
  • new loss of taste or smell
  • sore throat
  • congestion or runny nose
  • nausea or vomiting
  • diarrhea

What is the treatment for COVID-19?

COVID-19 treatment depends on the severity of illness and an individual’s risk. 
Medications are now available to reduce the risk of being hospitalized or dying from the disease. However, these treatments must be prescribed by a health care provider and started within days of the first symptoms. If you or your child has symptoms of COVID-19, it is very important to contact your health care provider as soon as possible to find out if treatment is recommended for your child.

What is long COVID?

Long COVID, also known as post-COVID syndrome, is the presence of one or more lingering symptoms that remain long after a child or teenager has recovered from COVID-19. Learn more about how we treat long COVID in our Post-COVID Clinic.

COVID-19 vaccination information for kids & teens

The U.S. Food and Drug Administration (FDA) has authorized the emergency use of the Pfizer BioNtech and Moderna vaccines to prevent COVID-19 in children 6 months and older. The FDA has authorized the Johnson & Johnson vaccine for people 18 and older. The Centers for Disease Control and Prevention (CDC) prefers that people get either a Moderna or Pfizer vaccination as a booster shot and recommend a Johnson & Johnson vaccine only in certain situations.

 

Who is eligible for a COVID-19 booster?

COVID-19 vaccine boosters can enhance or restore protection that might have diminished over time after your primary series vaccination.

Coronavirus | Community Resources

Boston Children’s Hospital is committed to improving the health and well-being of children and families in our community. We know that the COVID-19 crisis has caused parents and caregivers to face unprecedented levels of stress in their everyday lives. Many families continue to struggle with food insecurity, are worried about paying their rent or mortgage, have concerns about sending their child to daycare, or how to work with a child learning from home.

Food access and resources

Unfortunately, the COVID pandemic has led to more food insecurity for families throughout Massachusetts. It also has disproportionately impacted those living in low-income areas and the Black and Latino communities.

Boston Children’s is supporting its community partners and Boston community health centers to help families with food access, as well as with other needs around rental and utility assistance, and other basic household supplies.

Childcare and school resources

Boston Children’s Office of Community Health launched the Boston Childcare Support Initiative in July 2020 to support childcare providers in the communities most impacted by COVID. In total, 130 childcare providers have received grants. The grant amounts ranged from $3,500 to $10,000. These funds will be used by childcare providers to follow public health guidelines, adapt physical spaces, and cover increased costs for staff, overhead, personal protective equipment, and cleaning supplies.
