Can People Who Had Covid Be Carriers

How Will A Vaccine Prevent Covid

Why vaccinated people can still spread COVID-19

The coronavirus that causes COVID-19 has spikes of protein on each viral particle. These spikes help the viruses attach to cells and cause disease. Some of the coronavirus vaccines in development are designed to help the body recognize these spike proteins and fight the coronavirus that has them.

An effective vaccine will protect someone who receives it by lowering the chance of getting COVID-19 if the person encounters the coronavirus. More important is whether the vaccine prevents serious illness, hospitalization and death.; At this time, all three vaccines are highly efficacious at preventing serious illness, hospitalization and death from COVID-19.; Widespread vaccination means the coronavirus will not infect as many people. This will limit spread through communities and will restrict the viruss opportunity to continue to mutate into new variants.

When Do I Need To Present Proof

Travellers aged 12 or over must, irrespective ofthe mode of transport or whether they previously spent time in a high-risk area or area of variants of concern, as a rule carry with them a negative test result or proof of vaccination or recovery when entering the country. In the context of policing cross-border traffic into Germany, such proof may also be demanded by the Federal Police or the competent authority. Persons travelling by air must already present such proof to their carrier before departure. Also, travellers who, at any time within the last ten days prior to entry, spent time in an area classified as a high-risk area at the time of entry must present their carrier, e.g. the airline, with a negative test result or proof of vaccination or recovery before departure. In the context of policing cross-border traffic into Germany, this proof may also be demanded by the Federal Police. Travellers who, at any time within the last ten days prior to entry, spent time in an area classified as an area of variants of concern at the time of entry must present their carrier with a negative test result; proof of recovery or proof of vaccination is not sufficient in such cases. In the context of policing cross-border traffic into Germany, this proof may also be demanded by the Federal Police. Without such proof, carriage is not possible in any ofthe above cases.;

Protect Yourself When Caring For A Sick Pet

  • Follow similar recommended precautions;as for people caring for an infected person at home.
  • Members of the household who are fully vaccinated should care for the pet.
  • If you are at higher risk for severe illness from COVID-19, another household member should care for the pet, if possible.
  • People should wear a mask;and gloves in the same room or area as the sick pet.
  • Animals should not wear a mask. Do not try to put a mask on your pet.
  • Use gloves when handling the pets dishes, toys, or bedding and when picking up poop. Throw out gloves and place waste material or litterbox waste in a sealed bag before throwing away in a trashcan lined with a trash bag. Always wash your hands with soap and water immediately after cleaning up after your pet.
  • Clean your hands regularly throughout the day.
  • Wash hands: Wash your hands often with soap and water for at least 20 seconds each. Make sure everyone in the home does the same, especially after touching the sick pet or handling their dishes, toys, or bedding.
  • Hand sanitizer: If soap and water are not readily available, use a hand sanitizer that contains at least 60% alcohol. Cover all surfaces of your hands and rub them together until they feel dry.
  • Do not touch your eyes, nose, and mouth with unwashed hands.
  • Clean and then disinfect:
  • Follow cleaning and disinfecting recommendations found on CDCs Cleaning and Disinfecting Your Home

    After An Asymptomatic Infection Would Someone Still Have Antibodies Against Sars

    Most people are developing antibodies after recovery from COVID-19, likely even those without symptoms. It is a reasonable assumption, from what scientists know about other coronaviruses, that those antibodies will offer some measure of protection from reinfection.

    But nothing is known for sure yet.

    Recent serosurveys in New York City that check people’s blood for antibodies against SARS-CoV-2 indicate that as many as one in five residents may have been previously infected with COVID-19.

    Their immune systems had fought off the coronavirus, whether they’d known they were infected or not and many apparently didn’t.

    Q: What Effectiveness Data Supported The Emergency Use Authorization Of Pfizer

    A: The data to support the EUA of the Pfizer-BioNTech COVID-19 Vaccine include an analysis of 36,523 participants in the ongoing randomized, blinded, placebo-controlled international study, the majority of whom are U.S. participants, who completed the 2-dose vaccination regimen and did not have evidence of SARS-CoV-2 infection through 7 days after the second dose. Among these participants, 18,198 received the vaccine and 18,325 received saline placebo. The vaccine was 95 percent effective in preventing COVID-19 disease among these clinical trial participants with 8 COVID-19 cases in the vaccine group and 162 COVID-19 cases in the placebo group. Of these 170 COVID-19 cases, 1 in the vaccine group and 3 in the placebo group were classified as severe.

    Can Asymptomatic Carriers Test Positive For Covid

    Frank McGeorge, MD, Local 4’s Good Health Medical Expert

    Amber Ainsworth

    DETROIT People who have minimal or no coronavirus symptoms can spread the illness.

    Many people have wondered if those asymptomatic carriers would test positive for the virus. And if they can pass it to other people despite not showing symptoms, do they ever stop spreading it?

    If an asymptomatic person is shedding the virus, which means they could be infecting others, they would test positive for COVID-19.

    The second question doesnt have a clear answer yet.

    They will eventually stop spreading the virus, but when that happens or if asymptomatic people can recover and become immune is not known. Comprehensive surveillance of asymptomatic people has not been done, and there are no reliable antibody tests identified currently that would show that a person is now immune.

    People have also asked if it is possible to be infected with another virus when you have COVID-19.

    Yes, and a recent study has shown that 20 percent of people who tested positive for COVID-19 also had another virus. The most common viruses were rhinovirus, enterovirus, RSV and non-SARS-COV-2 coronaviruses, which are all frequent sources of a cold.

    The virus is thought to spread mainly from person-to-person.

    • Between people who are in close contact with one another .
    • Through respiratory droplets produced when an infected person coughs or sneezes.

    Can someone spread the virus without being sick?

    What To Do If You Think Your Pet Has The Virus That Causes Covid

    Coronavirus (COVID-19) Q&A: Is it possible for people to be carriers and show no symptoms?

    Pets infected with this virus may or may not get sick. Of the pets that have gotten sick, most only had mild illness and fully recovered. Serious illness in pets appears to be extremely rare.

    Pets that do have symptoms usually have mild illness that can be taken care of at home. If you think your pet is sick with the virus or if you have concerns about your pets health, talk to your veterinarian. Most pets that have gotten sick from the virus that causes COVID-19 were infected after close contact with a person with COVID-19.

    If your pet is sick and you think it might be from the virus that causes COVID-19, talk to your veterinarian.

    If you are sick with COVID-19 and your pet becomes sick,;do not take your pet to the veterinary clinic yourself. Call your veterinarian and let them know you have been sick with COVID-19. Some veterinarians may offer telemedicine consultations or other plans for seeing sick pets. Your veterinarian can evaluate your pet and determine the next steps for your pets treatment and care.

    Is It Ok To Get The Covid

    While there have been reports of severe allergic-type reactions in a very small number of patients, the CDC says that people with allergies to certain foods, drugs, insects, latex and other common allergens can still get the COVID-19 vaccine.

    If you have had a severe allergic reaction to injectables or other vaccines, be sure to discuss the COVID-19 vaccination with your doctor, who can evaluate you and assess your risk. The vaccine provider should observe you for 30 minutes rather than the routine 15 minutes after vaccination, and if you have an allergic reaction to the first shot, you may not receive the second.

    The CDC says that at this time, anyone who has a severe allergy to any of the vaccine ingredients;should not get that vaccine.

    How Do We Know a COVID-19 Vaccine Will Be Safe and Effective?

    Can Those Who Test Negative Continue To Transmit The Disease

    A study published in the American Thoracic Societys American Journal of Respiratory and Critical Care Medicine last week presented data from 16 patients who had tested negative according to two PCR tests. It found that at least half the patients could be shedding the virus even after testing negative – throat swabs on alternate days showed remnants of the virus in the body.

    The patients remained contagious between one to eight days after testing negative. The median age of patients was 35.5 years, and the average duration of symptoms was 8 days.

    The researchers also suggested that more severe infections could lead to longer shedding times, but more research is needed to study this claim.

    While the study was small, it adds to the evidence of asymptomatic spreaders. The;Diamond Princess, the cruise ship that was docked outside Japan because of positive cases, surprised experts worldwide with the rapid spread of infections despite cautionary measures and repeated testing. About 700 out of 3700 passengers ended up infected; studies have shown that around 18% of them showed no symptoms. These asymptomatic cases probably propelled infections in the vessel.;

    Can A Vaccinated Person Spread Coronavirus

    Immunologists expect vaccines that protect against viral illnesses to also reduce transmission of the virus after vaccination. But its actually tricky to figure out for sure if vaccinated people are not spreading the germ.

    COVID-19 poses a particular challenge because people with asymptomatic and pre-symptomatic infections can spread the disease and insufficient contact tracing and testing mean those without symptoms are rarely detected. Some scientists estimate that the number of asymptomatic COVID-19 infections in the overall population could be 3 to 20 times higher than the number of confirmed cases. Research suggests that undocumented cases of COVID-19 in people who either were asymptomatic or experienced very mild disease could be responsible for up to 86% of all infections, though other studies contradict the high estimates.

    In one study, the CDC tested volunteer health care personnel and other front-line workers at eight U.S. locations for SARS-CoV-2 infections weekly for three months, regardless of symptoms or vaccination status. The researchers found that fully immunized participants were 25 times less likely to test positive for COVID-19 than were those who were unvaccinated. Findings like this imply that if vaccinated people are so well protected from getting infected at all, they are also unlikely to spread the virus. But without contact tracing to track transmission in a larger population, its impossible to know if the assumption is true.

    New Study Shows How Much Asymptomatic People Spread Covid

    These 14 States Need to "Be Careful" With COVID Now, Virus ...

    Since the coronavirus pandemic began, scientists and public health experts have been puzzled by the role of asymptomatic spread. How many people have COVID-19, but no symptoms? And to what extent do those silent carriers contribute to the spread of the virus?

    Early estimates ran the gamut, but researchers are now settling on a much clearer number.

    A new model , developed by researchers with the Centers for Disease Control and Prevention, suggests that more than half of total COVID-19 transmissions come from those who have no symptoms. In other words, the majority of the spread is from silent carriers.

    Experts have been eager to better understand the issue of asymptomatic spread because the pandemic is harder to contain if people go out and infect others without realizing they themselves are ill.

    But one challenge has been that the term is not specific, said Eili Klein, an associate professor in the department of emergency medicine with Johns Hopkins University.

    There has been a definitional issue, Klein, who was not affiliated with the study, told HuffPost. What does asymptomatic mean?

    For example, some people are pre-symptomatic and may spread the virus before they realize they are ill. Others may never develop any symptoms but nonetheless pass the virus along, explained Klein.

    The new model suggests that both of those groups seem to play a key role in the spread of COVID-19.

    Q: What Data Did The Fda Evaluate To Support Emergency Use Authorization Of Pfizer

    A: The available safety data to support the EUA in adolescents in this age group include 2,260 participants ages 12 through 15 years old enrolled in an ongoing randomized, placebo-controlled clinical trial in the United States. Of these, 1,131 adolescent participants received the vaccine and 1,129 received a saline placebo. More than half of the participants were followed for safety for at least two months following the second dose.

    The most commonly reported side effects in the adolescent clinical trial participants, which typically lasted 1-3 days, were pain at the injection site, tiredness, headache, chills, muscle pain, fever and joint pain. With the exception of pain at the injection site, more adolescents reported these side effects after the second dose than after the first dose, so it is important for vaccination providers and recipients to expect that there may be some side effects after either dose, but even more so after the second dose. The side effects in adolescents were consistent with those reported in clinical trial participants 16 years of age and older. It is important to note that as a general matter, while some individuals experience side effects following any vaccination, not every individuals experience will be the same and some people may not experience side effects.

    Could You Be An Asymptomatic Covid

    Blood tests that check for exposure to the coronavirus are starting to come online, and preliminary findings suggest that many people have been infected without knowing it.

    Even people who do eventually experience the common symptoms of COVID-19 don’t start coughing and spiking fevers the moment they’re infected.

    William Petri is a professor of medicine and microbiology at the University of Virginia who specializes in infectious diseases. Here, he runs through what’s known and what isn’t about asymptomatic cases of COVID-19.

    Answered By Infectious Diseases Expert Sara Bares Md:

    This is a great and important question and the answer has changed since the emergence of the delta variant. Prior to delta, vaccines reduced transmission by about 90% and this was very reassuring. However, new data evaluating breakthrough infections in patients infected with the delta variant demonstrate similar viral loads in vaccinated versus unvaccinated patients. The viral load likely correlates with transmissibility.;

    In summary, the virus is changing and we are learning more about the new variants every day, but it is possible for someone who has been vaccinated to develop a breakthrough infection and spread the virus. This is why public health experts recently recommended that vaccinated people resume wearing masks in indoor public spaces and around those who are not vaccinated.

    Members Of Foreign Armed Forces

    Can Asymptomatic Coronavirus Cases Be Transmitted?

    There is also an exemption for persons who are members of foreign armed forces.

    This includes members of foreign armed forces within the meaning ofthe NATO Status of Forces Agreement, the NATO Partnership for Peace Status of Forces Agreement and the European Union Status of Forces Agreement who are entering or returning to the Federal Republic of Germany for operational reasons.

    This exemption does not apply to persons who at any time within the last 10 days prior to entry stayed in an area classified as an area of variants of concern at the time of their entry.
