It’s summertime! Enjoy your time outside, but don’t forget to take precautions to keep yourself and your family safe in the sun and heat. 

For tips about preventing heat-related illness, preventing child deaths from hot cars, and protecting children from window falls, see Staying Safe During the Summer Heat.  A new edition to that blog this year is a resource specifically for pregnant women: Safe Pregnancies in Extreme Heat. 

Protecting your skin from sun 

Too much sun can cause skin damage and skin cancer. It is important to keep our skin healthy and protect it from the sun’s harmful ultraviolet (UV) rays in any weather, not just in summer. 

Stay in the shade 

• When outside, find shade under a tree, an umbrella, or the stroller canopy. This is especially important for babies younger than 6 months. 

Wear sun-protective clothing, a hat, and sunglasses 

• Sun-protective clothing like lightweight long-sleeved shirts and pants or skirts can provide protection from the sun’s UV rays.  If not practical, at least try to wear a T-shirt or a beach cover-up, preferably of tightly woven fabric. Hats should have brims all the way around to shade the face, ears, and back of the neck, and should be made of a tightly woven fabrics. Sunglasses should block both UVA and UVB rays for the best protection. 

Use sunscreen 

Picking A Sunscreen
There are many sunscreens on the market. Sunscreens are assigned a sun protection factor (SPF) that rates how well they filter out UV rays. Higher numbers indicate more protection. The American Academy of Dermatology1 has shared the 3 essentials to look for in a sunscreen. 

• SPF 30 (or higher) 
• Broad-spectrum protection (UVA/UVB) 
• Water resistance  

A sunscreen that offers these 3 essentials can reduce the risk of: 

• Skin cancer 
• Sunburn 
• Melasma

If possible, avoid sunscreens with the ingredient oxybenzone in children because of concerns about mild hormonal properties. For areas of the body particularly prone to sunburn, such as the nose, cheeks, tops of the ears, and shoulders, choose a sunscreen with zinc oxide or titanium dioxide.

Applying Sunscreen
Here are some quick tips: 

• Apply sunscreen at least 15 to 30 minutes before going outside. 
• Make sure to use enough sunscreen to cover all exposed areas, including the face, ears, hands, back of knees, and feet.  Help is needed for hard-to-reach places like the back. 
• Reapply sunscreen every 2 hours, and especially after swimming or sweating.  
• Check the sunscreen’s expiration date. Sunscreen without an expiration date is good for no more than 3 years, less if it has been exposed to high temperatures. 
• Use sunscreen on cloudy days too, not just for sunny days. 

Recommendations for babies
The American Academy of Pediatrics² has the following recommendations for using sunscreen on babies: 

• For babies younger than 6 months: Use sunscreen on small areas of the body, such as the face, if protective clothing and shade are not available. 
• For babies older than 6 months: Apply sunscreen to all areas of the body, but be careful around the eyes. If your baby rubs sunscreen into their eyes, wipe their eyes and hands clean with a damp cloth. If the sunscreen irritates their skin, try a different brand or sunscreen with titanium dioxide or zinc oxide. If your baby develops a rash, talk with their doctor. 

Sunscreen and Insect Repellent
If you are outdoors in areas that may have mosquitoes, you should also protect yourself and your family from mosquito bites. Mosquitoes can spread germs through their bites that can cause illness. When you need to use both sunscreen and bug spray, apply sunscreen first and allow the sunscreen to absorb before applying bug spray.  Follow product label instructions on how often to reapply the insect repellent and sunscreen.  For more information, see Preventing Mosquito Bites: English | Spanish

Limit time in the sun during the peak hours 

• Plan activities for early morning, late afternoon, and evening to avoid being out when the sun rays are strongest (10 am – 4 pm)

The Centers for Disease Control and Prevention (CDC) is issuing this Health Alert Network (HAN) Health Advisory to notify clinicians and public health authorities of an increase in Oropouche virus disease in the Americas region, originating from endemic areas in the Amazon basin and new areas in South America and the Caribbean. Between January 1 and August 1, 2024, more than 8,000 cases of Oropouche virus disease were reported, including two deaths and five cases of vertical transmission associated with fetal death or congenital abnormalities. Countries reporting cases include Brazil, Bolivia, Peru, Colombia, and Cuba. In the United States and Europe in 2024, travel-associated cases have been identified in travelers returning from Cuba and Brazil. As testing and surveillance for Oropouche virus disease increase in the Americas, reports of cases from additional countries are expected. This Health Advisory advises on evaluating and testing travelers who have been in impacted areas with signs and symptoms consistent with Oropouche virus infection. It also raises awareness of the possible risk of vertical transmission (e.g., from gestational parent to fetus during pregnancy) and associated adverse effects on pregnancy and highlights prevention measures to mitigate additional spread of the virus and potential importation into unaffected areas, including the United States.

The Centers for Disease Control and Prevention (CDC) is issuing this Health Alert Network (HAN) Health Advisory to notify healthcare providers, public health authorities, and the public about current increases in human parvovirus B19 activity in the United States. Parvovirus B19 is a seasonal respiratory virus that is transmitted through respiratory droplets by people with symptomatic or asymptomatic infection. In the first quarter of 2024, public health authorities in 14 European countries observed unusually high numbers of cases of parvovirus B19. In the United States, there is no routine surveillance for parvovirus B19, and it is not a notifiable condition. Recently, CDC has received reports indicating increased parvovirus B19 activity in the United States. Data include increased test positivity for parvovirus B19 in clinical specimens and pooled plasma from a large commercial laboratory, and reports of clusters of parvovirus B19-associated complications among pregnant people and people with sickle cell disease. The proportion of people with IgM antibodies, an indicator of recent infection, increased among all ages from < 3% during 2022–2024 to 10% in June 2024; the greatest increase was observed among children aged 5–9 years, from 15% during 2022–2024 to 40% in June 2024. Among plasma donors, the prevalence of pooled samples with parvovirus B19 DNA >104 IU/mL increased from 1.5% in December 2023 to 19.9% in June 2024.

Measles is an acute viral illness typically presenting with fever, cough, coryza, and conjunctivitis, followed 3-5 days later by a rash. The maculopapular rash typically begins on the face and spreads down the torso and out to the extremities. The incubation period for measles ranges from 7-21 days after exposure and individuals are infectious from 4 days prior to rash onset until 4 days after rash onset. Measles is highly contagious and spreads via airborne transmission. More info...

(Santa Ana, CA) – The OC Health Care Agency (HCA) has confirmed a case of measles in an adult international traveler visiting Orange County (OC). The person visited the following locations in Orange County while infectious:        

• July 26 – Denny's Restaurant (1168 W. Katella Ave., Anaheim, CA 92802) from 7:00 p.m. – 9:00 p.m.
• July 27 – CVS Pharmacy (1803 S. Harbor Blvd., Anaheim, CA 92802) from 12:45 p.m. – 2:00 p.m.
• July 27 – Walmart (1120 S. Anaheim Blvd., Anaheim, CA 92805) from 1:00 p.m. – 3:30 p.m.
• July 28 – Anaheim Global Medical Center Emergency Department (1025 S. Anaheim Blvd., Anaheim, CA 92805) from 2:00 p.m. – 5:00 p.m.
• July 28 – CVS Pharmacy (1676 W. Katella Ave., Anaheim CA 92802) from 4:00 p.m. – 5:30 p.m.

The HCA has been working with Anaheim Global Medical Center to contact anyone who may have been exposed to this case and who are at increased risk of severe outcomes, such as infants, pregnant women, and those with compromised immune systems. People who were in the locations above around the same time(s) should:

• Review whether they are immune to measles or not. People who are not fully immunized against measles or who don’t know if they are immune to measles already should talk with a health care provider about receiving the Measles, Mumps and Rubella (MMR) vaccine.
• Monitor themselves for illness with fever and/or an unexplained rash from 7 days to 21 days after their exposure (the time period when symptoms may develop); if symptoms develop, stay at home and call a health care provider immediately for guidance.

“Measles is highly contagious and can lead to severe disease in some individuals. Common symptoms include fever, rash, cough, and red, watery eyes,” said Dr. Regina Chinsio-Kwong, County Health Officer. “It spreads very easily by air and by direct contact with an infected person. People are contagious from approximately four days before the rash appears through four days after the rash appears. Anyone suspecting that they have measles should call their medical provider before arriving at the medical office, to avoid exposing others to the measles virus. Immunization provides the best protection.”

Measles can be prevented through immunization:

• Infants should receive their first MMR vaccine at 12-15 months of age. The second dose of MMR is given at 4 to 6 years of age before going to school.
• Immunizing children, adolescents and adults is the best way to protect infants who are too young to receive the MMR vaccine.
• MMR vaccines are very safe. The benefits far outweigh any risks. Side effects are usually mild, such as soreness where the shot was given.
• Measles is found in many parts of the world, including Europe, Asia, Africa, and the Middle East. Receiving an MMR vaccine before international travel is recommended for those who have not already received two doses.
