The caravan of Central American migrants going through Mexico to the US border isn't ending. Instead, its participants will disperse into smaller groups after reaching Mexico City.While some will stay in Mexico to try to get refugee status there, others will continue north to the US border.Organizers of the caravan estimate that some 200 or so people will proceed all the way to the US border in the coming days, although the number could be higher. Last year, about 150 went all the way to the border, they said. 523

The Democratic-controlled House has approved a wide-ranging defense policy bill, even as President Donald Trump renewed his threat to veto the bill unless lawmakers clamp down on social media companies he claims were biased against him during the election. Trump tweeted Tuesday he will veto “the very weak National Defense Authorization Act,″ or NDAA, unless it repeals so-called Section 230, a part of the communications code that shields Twitter, Facebook and other tech giants from content liability. Trump also wants Congress to strip out a provision of the defense bill that allows renaming of military bases that now honor Confederate leaders. The defense bill now goes to the Senate. 699

The Food and Drug Administration warned pregnant women on Thursday of using some pain and fever medications during the second half of pregnancies.According to the FDA, these nonsteroidal anti-inflammatory drugs can cause rare but serious kidney problems in the unborn baby, which can cause pregnancy-related complications. Nonsteroidal anti-inflammatory drugs include ibuprofen, naproxen, diclofenac, and celecoxib. The FDA added that its warning does not apply to low-dose aspirin.“It is important that women understand the benefits and risks of the medications they may take over the course of their pregnancy,” said Patrizia Cavazzoni, M.D., acting director of FDA’s Center for Drug Evaluation and Research. “To this end, the agency is using its regulatory authority to inform women and their health care providers about the risks if NSAIDs are used after around 20 weeks of pregnancy and beyond.”The FDA says that warnings on prescription nonsteroidal anti-inflammatory drugs already advise of complications past 30 weeks. The newest guidance calls on health care providers to only prescribe the lowest effective dose for the shortest period possible for women 20 to 30 weeks into their pregnancy.More information on the warning can be found here. 1259

The Centers for Disease Control and Prevention issued new guidance that recent studies have indicated that cloth masks offer more protection against the coronavirus than previously thought.Previous guidance suggested that masks were best used for preventing the spread of the virus. The CDC now believes that masks are effective for both stopping the spread and reception of the virus. The CDC said on Tuesday that multi-layer cloth masks can both block up to 50 to 70% of fine droplets and particles and limit the forward spread of those that are not captured. Overall, cloth masks offer up to 80% blockage in human experiments. The CDC’s analysis found that cloth masks offer comparable protection as surgical masks.“Studies demonstrate that cloth mask materials can also reduce wearers’ exposure to infectious droplets through filtration, including filtration of fine droplets and particles less than 10 microns,” the CDC’s guidance said. “The relative filtration effectiveness of various masks has varied widely across studies, in large part due to variation in experimental design and particle sizes analyzed. Multiple layers of cloth with higher thread counts have demonstrated superior performance compared to single layers of cloth with lower thread counts, in some cases filtering nearly 50% of fine particles less than 1 micron.”The guidance says that mandatory mask wearing can help prevent the need to implement economic shutdowns.“Adopting universal masking policies can help avert future lockdowns, especially if combined with other non-pharmaceutical interventions such as social distancing, hand hygiene, and adequate ventilation,” the CDC said.In an interview with Andrea Mitchell of MSNBC, Dr. Anthony Fauci said that wearing masks is “two-way street.”"Recent data has now shown that as a matter of fact, there's also the added benefit to protect you from droplets and virus that's coming your way," Fauci said Tuesday on MSNBC."“You protect others," he added. "Their masks protect you. And your mask also protects you."In a separate interview on Tuesday, Fauci said that shut downs can be avoided.“We are not talking about shutting down,” Fauci told CNN’s Jake Tapper. “There is always that misunderstanding when we talk about public health measures. We are not talking about shutting down. We are talking about the four or five things I talk about all the time, wearing mask universally, keeping a distance, avoiding congregate settings indoors over outdoors and washing your hands.”Editor's note: A previous version of this story said "masks were best used for spreading the virus" when it should have said "masks were best used for preventing the spread of the virus." That has since been corrected. 2729

The Ebola virus outbreak in the Democratic Republic of Congo has killed 33 people, the World Health Organization said Sunday.An additional 43 suspected cases of Ebola were reported, including 13 confirmed by lab testing, according to WHO.The outbreak is spreading through five health zones in North Kivu province and one health zone in Ituri province, which poses geographic and political challenges, the WHO said. North Kivu borders Rwanda and Uganda and trade activity fuels heavy movement across the borders.North Kivu also hosts over 1 million displaced people and fighting between government forces and armed militant groups makes containing the highly infectious virus a challenge. 695
