What is already known about this topic?
The current Asian lineage avian influenza A(H7N9) virus (Asian H7N9) epidemic in China is the fifth and largest epidemic on record.
What is added by this report?
Human infections with Asian H7N9 virus were reported from more provinces, regions, and municipalities in China during the fifth epidemic than in the previous four epidemics combined. Because of antigenic variation between the Yangtze River Delta lineage viruses, the newly emerged high pathogenic Asian H7N9 viruses, and 2013 candidate vaccine viruses, new candidate vaccine viruses have been produced.
What are the implications for public health practice?
These candidate vaccine viruses, as well as others being developed by other World Health Organization Collaborating Centers for Influenza, could be used for vaccine production, clinical trials, stockpiling, and other pandemic preparedness purposes, based on ongoing public health risk assessment. CDC has partnered with China CDC, and other China government organizations, United Nations organizations, and surrounding countries to enhance surveillance and laboratory capacity to detect and respond to Asian H7N9 in animals and humans.

The annual Hajj, or pilgrimage to Mecca, Saudi Arabia, is among the largest mass gatherings in the world. In 2017, Hajj will take place from approximately August 30 to September 4. Umrah is a similar pilgrimage that can be undertaken at any time of the year, but is likely to be more crowded during the month of Ramadan (approximately May 27 to June 24).
Because of the crowds, mass gatherings such as Hajj and Umrah are associated with unique health risks. Before you go, you should visit a travel health specialist for advice, make sure you are up to date on all routine and recommended vaccines, and learn about other health and safety issues that could affect you during your trip.
In advance of this event, the Centers for Disease Control and Prevention (CDC) has developed the attached brief notice regarding Middle East Respiratory Syndrome Coronavirus (MERS-CoV) testing. Because of the potential increase in travelers returning from Hajj that may be ill, consider MERS-CoV testing if the person meets CDC’s patient under investigation (PUI) testing guidelines. CDC also recently updated reporting guidelines for a MERS PUI (EPI-X, July 25, 2017).
Virginia is outside of the path of totality, meaning we will see a partially eclipsed sun.
A solar eclipse will occur on August 21, 2017, during which nearly 86 percent of the sun will be blocked out in Virginia. The only safe way to look directly at the uneclipsed or partially eclipsed sun is through special purpose solar filters, such as “eclipse glasses” or hand-held solar viewers. Homemade filters or ordinary sunglasses, even very dark ones, are not safe for looking at the sun. They allow in too much sunlight.
Virginia is outside of the path of totality, meaning we will see a partially eclipsed sun. Outside the path of totality, you must ALWAYS use a safe solar filter to view the sun directly. Viewing the eclipse through a pinhole viewer is another option, but individuals should carefully follow the instructions for constructing a safe pinhole viewer. NASA also offers a guide for making your own pinhole projector. Children should always be supervised when using solar filters and pinhole projectors.
The CDC and NASA both have recommendations on how to safely enjoy the solar eclipse. The American Astronomical Society has a list of reputable vendors of solar filters & viewers.
All adults should get vaccines to protect their health. Even healthy adults can become seriously ill and pass diseases on to others. Everyone should have their vaccination needs assessed at their doctor’s office, pharmacy, or other visits with health care providers. Certain vaccines are recommended based on a person’s age, occupation, or health conditions (such as asthma, chronic obstructive pulmonary disease, diabetes or heart disease).
Vaccination is important because it protects the person receiving the vaccine and helps prevent the spread of disease, especially to those who are most vulnerable to serious complications (such as infants and young children, the elderly, and those with chronic conditions and weakened immune systems).
August 1-7, 2017 is World Breastfeeding Week. This year’s theme is Sustaining Breastfeeding Together. This year’s theme is about the importance of community and family support in a woman’s effort to breastfeed. As a collective, family, government, healthcare providers and employers all shift and impact a mother’s experience with breastfeeding.
Breastfeeding provides babies the perfect nutrition, and everything they need for healthy growth and development. Breastfeeding is good for mom too and reduces her risk for certain cancers. The commonwealth of Virginia protects the rights of families to breastfeed whenever and wherever baby is hungry.
The first week is focused on babies and young children. Vaccines give parents the safe, proven power to protect their children from 14 serious diseases before they turn 2 years old.
- Vaccinating your children according to the recommended schedule is one of the best ways you can protect them from 14 harmful and potentially deadly diseases like measles and whooping cough (pertussis) before their second birthday.
- Children who don’t receive recommended vaccines are at risk of (1) getting the disease or illness and (2) having a severe case of the disease or illness. You can’t predict or know in advance if an unvaccinated child will get a vaccine-preventable disease, nor can you predict or know how severe the illness will be or become.
- Vaccines don’t just protect your child. Immunization is a shared responsibility. Families, health care professionals and public health officials must work together to help protect the entire community – especially babies who are too young to be vaccinated themselves.
The FDA is advising consumers not to eat Caribeña brand Maradol papayas because they are linked to an outbreak of salmonellosis. Maradol papayas are green before they ripen and turn yellow, so consumers should not eat Caribeña brand regardless of the color. If anyone has these papayas in their home, they should dispose of them immediately. CDC reports 141 cases, 45 hospitalizations and one death from 19 states in the Salmonella Kiambu and Salmonella Thompson outbreak . The states involved are CT, DE, IA, IL, KY, LA, MA, MD, MI, MN, NC, NJ, NY, OH, OK, PA, TX, VA, and WI.

Pertussis is a very contagious disease characterized by severe coughing and caused by the bacteria Bordetella pertussis. Among vaccine-preventable diseases, pertussis is one of the most commonly occurring in the United States. The disease can be very serious in children less than 1 year of age when it can cause lung infections and, less often, seizures or inflammation of the brain. In rare cases, pertussis can result in death in children less than 1 year of age. Read the Pertussis FAQ.
Did you know July is National Grilling Month? Summer is a great time for outdoor events and activities, but it’s also peak season for foodborne illness. Follow these tips for a safe and healthy grilling season:
Raw meat, poultry, and seafood items should be the last items to go in your grocery cart. Separate these raw food items from other food in your shopping cart and grocery bags. Use individual plastic bags for each raw food item to protect against cross-contamination.
Keep meat, poultry, and seafood refrigerated until you are ready to grill. Keep these items below 40°F during transport and use an insulated cooler.
Wash your hands with soap before and after handling raw meat, poultry, and seafood. Don’t forget to also wash work surfaces, utensils, and the grill before and after cooking.
Meat and poultry color is not a good indicator of safety. Use a food thermometer to check that meat is cooked enough to kill harmful germs. If you use a smoker, keep temperatures inside the smoker at 225°F to 300°F to keep meat a safe temperature while it cooks.
- 145°F – whole cuts of beef, pork, lamb, and veal (stand-time of 3 minutes at this temperature)
- 145°F – fish
- 160°F – hamburgers and other ground beef
- 165°F – all poultry and pre-cooked meats, like hot dogs
After cooking meat and poultry on the grill, keep it hot at 140 °F or warmer until it’s time to serve.
Check your grill and tools
Clean the grill with a moist cloth or paper towel before cooking. Bristles from wire bristle brushes can also dislodge and stick into food the next time you cook. Check the grill’s surface before cooking to make sure no wires are stuck.
Toss marinades and sauces that have touched raw meat juices to avoid spreading germs to cooked foods. Harmful bacteria in raw meat and juices can contaminate cooked food; use clean utensils and a clean plate to remove cooked meat from the grill.
