How Serious Is Covid 19

Parcels From China Can Spread The Coronavirus

What you need to know about serious COVID-19 vaccine side effects

From previous research into coronaviruses similar to SARS-CoV-2, including those that cause SARS and MERS, scientists believe that the virus cannot survive on letters or packages for extended periods.

The explain that Although the virus can survive for a short period on some surfaces, it is unlikely to be spread from domestic or international mail, products, or packaging.

Is The Use Of Tear Gas Or Pepper Spray During The Covid

Tear gas and pepper spray are very painful. Your eyes, skin, nose and mouth burn. Exposed people cry, cough and sometimes vomit. You experience shortness of breath and your lungs produce large amounts of mucus. If a person who is unaware of having an active COVID-19 infection is exposed, he or she may spread the virus more widely to others.

Tear gas may also make it easier for SARS-CoV-2 to infect people. US military scientists have found that recruits exposed to tear gas in training develop lung injury and are more prone;to respiratory illnesses including viral influenza, as well as pneumonia and bronchitis, which viruses can cause. While not confirmed for COVID-19 directly, it is common knowledge that chemical lung exposures increase the infection risk.

Always wear a mask, especially during crowded protests. Protect your eyes with safety goggles or glasses in case you are hit by objects, or where there is dust and smoke. When the police use tear gas, move away quickly. If you are exposed, remove your clothes and shower with lots of water and soap. If your eyes are exposed, rinse 10-15 minutes with plenty of plain water.

If Youre Sick Or Caring For Someone Whos Sick

If youre infected with COVID-19, even if not ill, follow the advice of your local public health authority for isolating at home. Most people with mild symptoms will recover on their own.

Adults and children with mild COVID-19 symptoms can stay at home while recovering. You dont need to go to the hospital.

If youre caring for someone at home who has or may have COVID-19, you should follow the appropriate precautions to prevent the spread of illness.

The only way to confirm you have COVID-19 is through a;laboratory test.

Follow the testing directions provided by your local public health authority if you have:

  • symptoms
  • been exposed to a person with COVID-19

People who are partially or fully vaccinated may still be asked to get a COVID-19 test.

If youve been tested and are waiting for the results, follow instructions:

Government To Overhaul England’s Traffic Light System For Foreign Travel

Government ministers are to slash the number of red list countries by up to half as part of plans to simplify Englands rules for international travel, with sources claiming it would incentivise vaccination, Aubrey Allegretti reports.

The traffic light system will be overhauled, with the amber tier removed so there is a clearer distinction between go and no go destinations.

Those who have been double-jabbed are likely to be able to escape quarantine or the need for costly PCR testing upon arrival, while unvaccinated passengers will still face those hurdles.

It will be made much simpler, particularly for those who are double-vaxxed, a government source said.

It is understood the new red list is likely to be focused on countries where there is a significant concern about Covid variants.

Government insiders said the ultimate aim was to simplify the rules, after Labour called for the amber list to be scrapped in order to clarify guidance on which destinations are relatively safe and which are not.

However, they also admitted it would have the effect of providing a greater incentive to the 10% of those eligible to be vaccinated who have not yet had their first jab, given the extra money people will have to fork out for a PCR test instead of a cheaper lateral flow one, as well as avoiding the hassle of having to self-isolate.

Ministers will gather on Friday morning to sign off the plans and an announcement is expected later that afternoon.

All employees have a legal right to a safe work environment.

If youre uncomfortable with your employers COVID-19 safety protocols, there are ways to take action:

  • Most employers aim to do the right thingso first try resolving the issue internally. By law, you cant be retaliated against for expressing these concerns.
  • Theres safety in numbersso join forces with colleagues.
  • If you get fired for refusing to work in an unsafe environment, you should be entitled to unemployment compensation. Be prepared for a legal battle if your employer contests the claim.;
  • You can file a formal complaint with the Occupational Safety and Health Administrationbut dont expect a speedy resolution.;
  • Know your area: Absent robust federal action, some states are taking a more active role to protect workers.
  • Look to labor unions: During the pandemic, some are stepping up to help workers even if they arent members.;

What Determines Whether A Virus Disappears Or Becomes Endemic

Two main clues help us predict whether a virus is going to stick around. First, we consider the viruss origins. If it came from animals and could still be circulating in animals, then no matter how good we are at getting rid of it in humans, animals could always bring it back. Thats true with influenza: Even if a certain strain disappears, a new one might emerge from animalsas weve seen with avian viruses.

But with a major outbreak like COVID-19 already underway in humans, the big question is how good humans are at developing immunity. And, if they gain immunity, does it stick, or does it fizzle out over timeleaving the door open a crack for the virus to return? As the first cases get further and further out from the point of infection, that data will give us a better idea of what to expect.

Strict Measures Are Critical For Slowing The Spread Of The Disease

Near the beginning of the pandemic, public health experts directed their efforts toward “flattening the curve.” If you mapped the number of COVID-19 cases over time, the expectation was that it would peak at some pointon a graph this peak would mirror a surge in patients . Flattening the curve would mean there would be fewer patients during that period, and hospitals would be better able to manage the demands of patients who are sick with COVID-19 and other illnesses.

But last November/December as winter approached, a steady increase in cases in the U.S. was becoming what some described as a third wave , if not a continuation of a single wave that started in the spring and never stopped. As cold weather drove more people indoors, many government officials around the country halted some of the plans they had to reopen, implementing new restrictions that included curfews, limiting the number of people who could gather indoors, and establishing mask mandates.

The idea is that if enough people are protected either because they have had the disease or theyve been vaccinated, herd immunity will start to protect even those people who have not been infected.;While the timeline for herd immunity is still uncertain, researchers believe we will likely not reach it any time soon.;And experts are concerned that outbreaks of the Delta variant could affect overall progress.;

Do We Need To Worry About Catching Covid

When toilets flush, the turbulent water aerosolizes fecal matter, creating particles known as bioaerosols. Bioaerosols can linger in the air until they are removed via bathroom exhaust or air filtration, settle on surfaces, or are inhaled.

Viable SARS-CoV-2 has been detected in stool samples, making bioaerosols from toilets a potential exposure pathway. However, there are no confirmed reports of transmission this way. Taking simple precautionsrunning bathroom ventilation or opening windows, closing the toilet lid before flushing, and washing handsis prudent.;In 2003, sewage vapors were linked to an apartment building SARS outbreak in China. A recent case study related to SARS-CoV-2 reported similar findings. In both cases, empty trapways in floor drains failed to stop vapors from wafting throughout building pipes and into other apartments. Floor drains and other infrequently-used drains should be filled with a little water to prevent sewage vapor from passing.;Joseph Allen, DSc, MPH, is an associate professor and director of the Healthy Buildings program at Harvard T.H.

  • By sharing your information with others, you can slow the spread of COVID-19.
  • Learn how to identify and talk with your close contacts.
  • Tell people in your family and others you had close contact with while contagious that they need to stay home, get tested, and monitor their health to make sure they do not get sick and infect others.
  • People with COVID-19 are considered to be contagious both while they are sick and for 2 days before symptoms began. People who tested positive for COVID-19, but never developed symptoms, are considered to be infectious from 2 days before the positive test to 10 days after the positive test.
  • Let your close contacts know that the health department may call, and ask them to speak with health department staff if they do call.;
  • VisitExposure to COVID-19 to learn more about how to monitor your health and protect your community if youve been exposed to a person with COVID-19.
  • Answer the call. Yourlocal health department might contact you to check-in on your health, ask you to stay at home to isolate, discuss who youve been in contact with, and notify your contacts. This is part of contact tracing. You may also get a text message with more information from VDH.

    If I Have A Heart Condition What Precautions Should I Take To Avoid Serious Covid

    It is very important to continue taking heart medications as prescribed and urgently address any cardiac symptoms that arise.;;Early in the outbreak, there were concerns that Angiotensin-converting-enzyme inhibitors may increase the risk of COVID-19 illness, but medical organizations have concluded that they pose no increased riskand have proven lifesaving benefits.;However, for patients who require a ventilator, it may be necessary to adjust or stop certain cardiac medications based on blood pressure and heart status.;Symptoms for COVID-19 and an active cardiac issuesuch as shortness of breath and chest discomfortcan be similar. If heart medications are not being taken consistently to control cardiac symptoms, it is more difficult to distinguish between COVID-19 and a cardiac event.;;While some patients are understandably apprehensive about seeking care during the pandemic, it is crucial to not delay. Research in Italy showed that visits to cardiac units halved during the outbreakcoinciding with an increase in out-of-hospital deaths from heart attacks.

    What Does Successful Risk Communications Look Like

    When you think of containing an epidemic, from Ebola to coronavirus, labs and disease surveillance are often top of mind. Risk communications, however, is a key aspect in shaping the course of an epidemic, and how prepared people are to combat it.

    People need timely, accurate and easy-to-understand information that encourages protective behavior without inciting panic. Information based on the changing risk of transmission and not politics, fear or stigma is critical.

    As coronavirus spreads, government, media and others need to elevate accurate information sources and built community trust while combatting misinformation.

    One Of The Symptoms Of Covid

    Shortness of breath refers to unexpectedly feeling out of breath, or winded. But when should you worry about shortness of breath? There are many examples of temporary shortness of breath that are not worrisome. For example, if you feel very anxious, it’s common to get short of breath and then it goes away when you calm down.

    However, if you find that you are ever breathing harder or having trouble getting air each time you exert yourself, you always need to call your doctor. That was true before we had the recent outbreak of COVID-19, and it will still be true after it is over.

    Meanwhile, it’s important to remember that if shortness of breath is your only symptom, without a cough or fever, something other than COVID-19 is the likely problem.

    What Makes A Breakthrough Infection More Likely


    Nationwide, on average more than 5% of COVID-19 tests are coming back positive; in Alabama, Mississippi and Oklahoma, the positivity rate is above 30%. Lots of coronavirus circulating in a community pushes the chance of breakthrough infections higher.

    The likelihood is greater in situations of close contact, such as in a cramped working space, party, restaurant or stadium. Breakthrough infections are also more likely among health care workers who are in frequent contact with infected patients.

    For reasons that are unclear, nationwide CDC data found that women account for 63% of breakthrough infections. Some smaller studies identified women as the majority of breakthrough cases as well.

    What Is Cryptic Transmission And What Is Its Significance In The Covid

    Cryptic transmission is the term that is used when there is no direct contact between person 1 shedding the virus and person 2 contracting it.

    It is an important indicator of community prevalence of a virus. There is essentially enough circulating virus in a community to transmit the same strain of the virus between individuals who are not directly linked.

    In the case of the COVID-19 outbreak, this term came into the lexicon after University of Washington researchers sequenced the COVID-19 genome from Snohomish County, Washington, which showed a direct genetic link from the first 2 cases in Washington though they had no known contact. This indicated there was significant community spread, and likely evidence the virus had been circulating for weeks by that point. As I noted on Twitter, the key takeaway is this is going to be a critical path for viral transmission given the potential infectivity prior to the manifestation of symptomsand what will ultimately make it so hard to control the spread of the virus.

    Why Is Diabetes Considered A Risk For Severe Covid

    For people with diabetes, factors that potentially play a role in increasing their risk of developing a more serious case of COVID-19 include:

    • The presence of chronic medical conditions such as cardiovascular disease, hypertension, and obesity that also increase the risk for COVID-19
    • Impaired function of white blood cells that fight infection, and an exaggerated inflammatory response by the body toward the SARS-CoV-2 virus
    • Increased expression of an enzyme in the lungs, heart, kidneys, and pancreas that acts as a portal for the novel coronavirus to enter human cells

    To stay healthy, optimal diabetes management is important, including controlling blood pressure and cholesterol levels. People with diabetes should stay hydrated, carefully record blood glucose and ketone readings, andif a person develops symptoms such as fever, cough, or shortness of breathcontact their health care provider immediately.

    Do We Know If The Virus Can Enter Through The Eye

    Mild COVID-19 symptoms can quickly turn serious, experts warn

    There is no evidence yet that SARS-CoV-2, the virus that causes COVID-19, can gain entrance through the eye. However, there are now reports of the virus being present in tears and on the surface of the eye. While most of those patients were very ill, it is likely that the surface of the eye and its tears may contain virus and its best to avoid touching the eye or tears of any potential patient.

    While we do not yet have any direct evidence that the virus is infectious if it touches the eye, we must assume that it is a possibility. As the general precautions all stress, anyone who touches someone who may be infected should wash their hands immediately, and refrain from touching their own face .
