By\u00a0Allyson Waller\r\nFive Democratic members of the Texas House of Representatives who traveled to Washington D.C. last week have tested positive for the coronavirus, according to the Texas House Democratic Caucus.\r\nThe five lawmakers are among\u00a0House Democrats who fled\u00a0to Washington, D.C., to stave off GOP priority voting bills during the special legislative session. The members who tested positive all have been fully vaccinated, which helps protect against severe illness. All of the lawmakers are showing no symptoms or only mild symptoms.\r\nThe House Democratic Caucus announced on Saturday that three Democrats had tested positive. After further precautionary testing, two more members tested positive for COVID-19, the caucus announced late Sunday.\r\nSan Antonio Rep.\u00a0Trey Martinez Fischer\u00a0said Sunday he was among the two new positive tests.\r\n"Today, I received a positive COVID-19 rapid antigen test result. I am fully vaccinated and had tested negative on Friday and Saturday. I am quarantining until I test negative, and I am grateful to be only experiencing extremely mild symptoms," he said in a statement, which urged the public to get vaccinated and said he will continue to participate in the quorum break.\r\nEarlier Sunday, Austin Rep.\u00a0Celia Israel\u00a0said in a statement she was among the initial three to test positive.\r\nThe House Democratic Caucus said it would not identify lawmakers who test positive out of respect for their privacy. But the caucus has started additional precautionary measures, like providing daily rapid tests for all lawmakers and their staff in Washington, D.C.\r\nOn Friday night, one member tested positive for the coronavirus and immediately alerted colleagues, who, in addition to staff members, took rapid tests. On Saturday morning, two additional members tested positive after taking rapid tests. The cases were\u00a0first reported\u00a0by the Austin American-Statesman.\r\nIn a statement, Rep.\u00a0Chris Turner of Grand Prairie, the caucus chair, said the caucus is adhering to guidance from the Centers for Disease Control and Prevention and following protocols.\r\nAccording to the CDC, fully vaccinated people do not need to quarantine if they have been in close contact with someone who has tested positive and they are showing no symptoms. Also, if traveling in the United States, fully vaccinated people do not need to get tested or self-quarantine before or after travel.\r\n\u201cThis is a sober reminder that COVID is still with us, and though vaccinations offer tremendous protection, we still must take necessary precautions,\u201d Turner said. \u201cWe are in touch with public health experts in Texas to provide additional guidance. Our caucus will follow all recommendations from public health experts as we continue our work.\u201d\r\nA small percentage of vaccine breakthrough cases, in which a fully vaccinated person tests positive for the coronavirus, have been expected, according to the CDC, but they are rare and do not discount the effectiveness of COVID-19 vaccines.\r\nThe number of average\u00a0coronavirus cases reported in Texas each day in the last week has increased by almost 1,000 cases compared with the average a week ago, according to data from the Texas Department of State Health Services.\r\nHospitalizations have also increased, and as of July 14, more than 2,500 Texans were hospitalized. On Saturday, the state hit a positivity rate of more than 10%. The positivity rate measures how prevalent the virus is in Texas based on positive test results.\r\nThe highly contagious delta variant of the coronavirus has raised the alarm of some health experts. At least three cases from a recent outbreak at a\u00a0Houston-area church camp\u00a0have been confirmed to be the delta variant.\r\nIn recent days, Republican lawmakers, who have criticized House Democrats\u2019 move to break quorum, have urged their colleagues to return to the Capitol before the current special session ends Aug. 6. More than 51 Democrats left the state last week, leaving the House without the minimum number of lawmakers required to conduct business. However, a handful of Democrats have remained adamant that they don\u2019t plan on returning to the state any time soon.\r\nIn a statement on Saturday, House Speaker\u00a0Dade Phelan\u00a0wrote on Twitter that he extended his \u201cprayers for safety and health\u201d to Democratic caucus members.\r\nPhelan, a Beaumont Republican, said on Thursday he would charter a plane this weekend to Austin to retrieve Texas Democrats from the nation\u2019s capital. A move to issue a \u201ccall of the house,\u201d which permits lawmakers to track down lawmakers who have fled the House chamber, passed in the House on Wednesday.\r\nHowever, Texas law enforcement does not have jurisdiction in Washington, D.C., so it\u2019s not clear if the procedural move has any power until lawmakers return to the state.\r\nThis story originally published by the Texas Tribune.
