FDA Approves First Test for Zika in Human Blood

The first test to detect the Zika virus in human blood has been approved by the U.S. Food and Drug Administration.

The test is called the ZIKV Detect 2.0 IgM Capture ELISA and is made by Seattle-based InBios, which makes tests for other viruses such as West Nile and dengue, CBS News reported.

Until now, the only FDA-approved tests for Zika were to detect virus antibodies and were only for emergency use.

Zika infection during pregnancy can cause severe birth defects, including abnormally small heads and underdeveloped brains. The mosquito-borne virus can also cause a nervous system disorder called Guillain-Barre syndrome.

Zika "continues to be a problem in many parts of the world," according to the U.S. Centers for Disease Control and Prevention. There is no vaccine to prevent Zika infection or medicine to treat it.

In the United States, CDC data show that the majority of the 5,600 cases of Zika in 2016 and 2017 occurred in people who traveled to affected areas, but there were 339 mosquito-born infections in Florida and Texas, CBS News reported.

Some CBD Oils, Marijuana-Derived Drug Now Allowed on Flights: TSA

Airline passengers will now be allowed to travel with some forms of CBD oil and an epilepsy drug derived from marijuana, the U.S. Transportation Security Administration says.

Previously, all forms of marijuana were prohibited in carry-on bags and checked luggage, the Associated Press reported.

The policy change applies to the marijuana-derived drug Epidiolex, which is used to treat epilepsy in children, and CBD oil "as long as it is produced within the regulations defined by the (2018) law," that legalized hemp and hemp derivatives, the TSA says.

Hemp-derived CBD is low in or has no THC, the chemical in marijuana that gives users a high, the APreported.

Other forms of marijuana, including CBD oils that have THC and cannabis-infused products that are still illegal under federal law, remain banned under the TSA's new rules.
