Is it Flu or Zika?

Zika o Flu

Flu (influenza)

How flu germs are spread

The flu spreads from person to person by droplets made when people who have the flu cough, sneeze, or talk. Viruses can also spread on surfaces, but this is less common. People with the flu might be able to spread the virus before illness starts and can spread it during their illness.

Who gets the flu?

Anyone can get the flu. Some people, such as young children, older adults, people with health conditions, and pregnant woman are at risk of serious complications. Flu viruses continuously change, so people can get infected with flu viruses multiple times in their lifetime.

Getting the flu vaccine and taking preventative actions to stop the spread of germs can help protect against the flu.

Zika Virus

How Zika is spread

Zika is primarily spread to people through the bite of infected Aedes aegypti and Aedes albopictus mosquitoes. These types of mosquitoes live in many parts of the world including parts of the United States.

Zika can also spread in other ways:

  • A pregnant woman with Zika virus can pass it to her fetus.
  • A person with Zika virus can pass it to his or her sex partners.
  • Zika may also spread through blood transfusion.

Who gets Zika?

Anyone who lives in or travels to an area with Zika and has not already been infected can get Zika. Mosquitoes that spread Zika virus bite during the day and night. Once a person has been infected with Zika virus, they are likely to be protected from future Zika virus infections.

Preventing Zika is especially important for pregnant women to prevent Zika-related birth defects. There is no vaccine to prevent Zika, but methods can be used to protect oneself from mosquito bites and from sexual transmission.

What do you know about Aedes aegypti mosquitoes?

Mosquito Control

Control Larvae

Once mosquito eggs hatch, they become larvae and then pupae. Both larvae and pupae live in standing water. Dumping or removing standing water in and around your home is one way to control larvae. For standing water that cannot be dumped or drained, a larvicide can be used to kill larvae. Larvicides are products used to kill larvae before they become biting adults. Controlling larvae before they become adults can minimize widespread use of insecticides that kill adult mosquitoes.

Control Adult Mosquitoes

Adult mosquitoes can spread viruses (dengue, Zika, or others) that make you sick. When surveillance activities show that adult mosquito populations are increasing or that they are spreading viruses, professionals may decide to apply adulticides to kill adult mosquitoes. Adulticides help to reduce the number of mosquitoes in an area and reduce the risk that people will get sick. The public and professionals can use US Environmental Protection Agency (EPA)-registered adulticides according to label instructions.

Visiting Friends or Family in an Area with Zika?

When traveling to visit friends or family, think about possible health risks during your trip. If Zika is in the area you are visiting, protect yourself and loved ones from mosquito bites and sexual transmission of Zika

Communication Tips: "Processing Information during a Crisis"



Processing Information during a Crisis


People affected by a crisis take in information, process information, and act on information differently than in non-crisis times. By understanding how people receive information in an emergency, responders can be better prepared to effectively communicate with them.


During a crisis, there are four ways people process information:


1. We simplify messages.

Under intense stress and potential information overload, we can miss important details in health and safety messaging.

2. We hold on to current beliefs.

Sometimes, crisis communicators must ask people to take actions that conflict with their beliefs. Changing our beliefs during a crisis or emergency is difficult.

3. We look for additional information and opinions.

We remember what we see and tend to believe what we’ve experienced. Consequently, we want messages confirmed before taking action. This confirmation first—before we take action—is very common in a crisis.

4. We believe the first message.


The speed of a response is also an important factor in reducing harm during a crisis. The first message may become the accepted message, even though more accurate information may follow. When more complete information emerges, we often compare it to the first message.


Because of how people process information during a crisis, it is critical for emergency communicators to:


  • Use simple, consistent messages
  • Ensure that messages come from a credible source
  • Release accurate messages as soon as possible


By doing so, emergency communicators are better able to protect the health and safety of the public.
