What is the current situation?
Public health officials have reported that mosquitoes in Guinea-Bissau are infected with Zika virus and are spreading it to people.
Because Zika virus is primarily spread by mosquitoes, CDC recommends that travelers to Guinea-Bissau protect themselves from mosquito bites.
Sexual transmission of Zika virus is also possible, so you should use condoms or not have sex during your trip.
Many people infected with Zika virus do not get sick. Among those who do develop symptoms, sickness is usually mild, with symptoms that last for several days to a week. Guillain-Barré syndrome (GBS) is a rare disorder that can cause muscle weakness and paralysis for a few weeks to several months. CDC research suggests that GBS is strongly associated with Zika; however, only a small proportion of people with recent Zika virus infection get GBS. Most people fully recover from GBS, but some have permanent damage. For more information, see Zika and GBS.
As more information becomes available, this travel notice (CDC.gov) will be updated. Please check back frequently for the most up-to-date recommendations.
